Description of this part for the microscope.

Olympus BHM
- but possibly also with others from the BH series

This illuminator allows operation in the following modes:
- EPI-BF (bright field in reflected light)
- EPI-DF (dark field in reflected light)
- EPI POL (polarization after installing a filter)

The set includes the light source (bulb).

Note - originally these illuminators work with Olympus NEO series objectives, but I have seen DIY modifications for standard RMS objectives.

Fits condensers:
- PZO KPI-2 (Pluta / Nomarski DIC)
- PZO K4Ph (phase contrast Ph, PhA, PhS, A)
- PZO K3Ph (phase contrast Ph, PhA, PhS, A)
- PZO K3Ph1 (phase contrast Ph, PhA, PhS, A)
- PZO KFL (phase contrast / darkfield for fluorescence)
- PZO KFF
- PZO K3Phz (variable phase contrast Phz)

This upper lens allows conversion of the mounting standard from PZO 39.5 mm to the 37 mm standard and the use of PZO condensers on many other microscopes, e.g. Olympus BH / CH-2 or Lomo MBB

This microscope element can solve the following issues:
- How to mount PZO DIC on a Lomo microscope?
- Can I install a PZO DIC KPI2 condenser on an Olympus CH-2 microscope?
- Can I use PZO phase contrast on my non-PZO microscope?
- Does PZO phase contrast or DIC work on a microscope with a 37 mm condenser mount?

08 160/-
Color correction: Planachromat
Numerical aperture: 0.08
Tube length: 160 mm
Focal length: 45 mm
Cover glass: no
Immersion: no
Thread: RMS

This lens provides an excellent, wide image, and because it doesn't require a cover glass, it's often used for macro photography and stacking.

Important - this lens is not suitable for taking photos using the "direct-projection" technique, as it requires plan-compensation optics.

A microscope objective with such low magnification is used, among others, in the following fields:
- tissue overview examination in pathomorphology
- observation of insects
- observation of minerals
- observation of inclusions in amber
- handwriting analysis
- observation of micromollusks
- and many others

Focal length: 45 mm
Cover glass: no
Immersion: no
Thread: RMS
Info: PI = polarization-interference objective (red ring).

Compatible with the following PZO condensers:
- PZO KPI 2
- slit condenser
PI objectives are among the components of the PZO UPI set (i.e. the so-called DIC).

VERY IMPORTANT: the marking on the objective is "PI" (in lowercase: "pi"), meaning [P]-polarization [I]-interference.
In many descriptions available on the Internet, you can find information that this is a PLAN objective. This is an ERROR caused by misinterpreting the marking as PL.

Note: another INCORRECT piece of information often found online is that these are DIC objectives. This is not true.
DIC according to Pluta (niem: DIC nach Pluta), sold by PZO, achieves the DIC effect (i.e. a 3D relief image) using standard achromatic PZO objectives (and not only those). Objectives marked PI with a red ring are not required for this.

It can be used with any microscope from any manufacturer that supports RMS objectives, TL=160 mm, FL=45 mm.

Numerical aperture: 0.40
Tube length: 160 mm
Focal length: 33 mm
Cover glass: yes, 0.17 mm
Thread: RMS + Pol adapter
Info: P = Polarization

This is an objective designed for transmitted light work with a cover glass.

The RMS thread objective is mounted on a dedicated slide-in adapter that allows it to be used in Lomo MIN series and Lomo Polam series microscopes. Of course, the objective can be unscrewed and another objective can be mounted in the adapter.

The objective itself, once removed from the adapter, is a standard objective that can be used in virtually any microscope with an RMS thread. It is a so-called "short objective" (focal length 33 mm). When a 12 mm adapter is added, the total length becomes 45 mm, allowing it to be used with newer microscopes from any manufacturer.

Lomo polarization objectives with RMS thread can be installed in an RMS-M27 adapter and then used in microscopes such as Lomo Biolam M, Lomo Biolam I, Lomo Lumam, or Lomo ML-2. I have also frequently seen such objectives used in Zeiss Axio series microscopes with M27 thread.

The Pol adapter also allows precise centering of the objective relative to the entire optical path - this requires tools (keys / tools).

Info: I have repeatedly seen information stating that this RMS-Pol adapter is compatible with Leitz Wetzlar polarization microscopes - however, I have not personally verified this.

In summary, this objective is dedicated to Lomo MIN-1, MIN-4, MIN-5, MIN-6, MIN-8, Lomo Polam R-113, Polam L-211, Polam L-213, Polam R-311, Polam LMPR microscopes - but it is practically compatible with any microscope from any manufacturer that supports 160 mm objectives.

Additionally, this objective is very often used for macro photography even without a microscope. This objective does not require a cover glass and works in the "direct-projection" technique, meaning it can be connected directly to a camera without additional optics. This allows achieving a very high magnification scale and great depth of field across the entire image when using focus stacking. The fact that this is a polarization objective (i.e. stress-free optics without internal glass tensions) further improves image quality at high magnifications.

Tube length: 160 mm
Focal length: 45 mm
Cover glass: yes, 0.17 mm
Immersion: yes, oil
Thread: RMS
Specimen protection: yes - spring-loaded
Info: PHACO 3 = phase contrast

Some important information about this objective:
- the designation "EF" means "Extended Field" - this is a semi-plan achromatic objective with an 18 mm field of view, which should be taken into account when selecting suitable eyepieces
- the semi-plan achromatic correction is "almost flat" - it is no longer an achromat, but not yet a plan achromat
- this objective can be used in brightfield, but phase contrast operation requires a compatible phase contrast condenser or a slide (slider) with a phase ring diaphragm
- the designation PHACO 3 means that for phase contrast operation a phase contrast condenser set to ring "3" should be used (the equivalent setting used by Zeiss is called "Ph3")
- this objective can be used with microscopes designed for objectives with a 170 mm tube length, but in such a case the optical path must be extended by 10 mm - most commonly by pulling the eyepieces out of the tubes by 10 mm

This objective can be used with any microscope from any manufacturer together with a compatible phase contrast condenser. Naturally, the microscope must be compatible, i.e. it must support RMS objectives, TL=160 mm and FL=45 mm - or have adapters that make such adaptation possible (for example thread adapters).

Manufacturer: Lomo
Model: PLAN 25x0.50 P
Original designation: ЛОМО ПЛАН 25х0,50 П
Magnification: 25x
Numerical aperture N.A.: 0.50
Tube length: 160 mm
Cover glass: yes, 0.17 mm thickness
Immersion oil: no - this is a dry objective
Focal length: 45 mm
Thread type: RMS
Additional designation: P (Cyrillic: П) indicates that this objective is designed for use with polarized light
Special features: built-in iris diaphragm
Year of manufacture: 1976

This objective has a standard RMS thread and TL=160 mm, which means it can be used with the vast majority of microscopes from virtually any manufacturer, including Olympus, Zeiss, Nikon, PZO, Carl Zeiss Jena, Reichert, Wild and many others.

The built-in iris diaphragm allows, among other things, precise centering of the objective, because in a polarizing microscope the following diaphragms may operate simultaneously:
- field diaphragm in the illuminator
- aperture diaphragm (or two aperture diaphragms) in the condenser
- iris diaphragm in the microscope objective
- iris diaphragm in the eyepiece head
and accurate centering of all of them relative to each other is very important in polarized-light observations.

Objectives marked "P" / "Pol" feature a special construction in which the lenses are mounted and cemented in a way that prevents mechanical stress. They can be used both for conventional brightfield microscopy and for observations in polarized light.

2 microscopes with a reflected light illuminator.

Olympus BH2-NAN-2 analyzer slider:
Slider type: rotatable polarizing analyzer
Rotation: the analyzer rotates within a range of 0-45 degrees
Marking on the slider: Olympus BH2-NAN-2
Model in the manufacturer catalog: BH2NAN2
Dimensions: width 45 mm, thickness: 7.5 mm, overall length: 68.5 mm, length of the inserted part: 48.5 mm
Intended use: for the EPI reflected light illuminator

Olympus polarizer slider:
Slider type: rotatable polarizer
Rotation: the polarizer rotates within a range of 0-360 degrees
Marking on the slider: none
Model in the manufacturer catalog: unknown
Empty position: yes - the polarizer has two positions, one with the polarizing filter and the other empty
Dimensions: width 45 mm, thickness: 6 mm, overall length: 85 mm
Intended use: for the EPI reflected light illuminator
Notes: the absence of any marking on the slider suggests that it is not a pull-out slider, but is permanently mounted in the EPI reflected light illuminator - it can, however, be moved between the empty position and the polarizer position

If you want to use this slider in a different microscope - check the shape and the exact dimensions shown in the photos.

Please note - the commonly used terminology is slightly disordered, and foreign as well as incorrect names are often used. The most common mistake is that the analyzer is called a polarizer - and unfortunately this mistake is so frequent that it has to be taken into account. Here are examples of the names in use:
- polaryzator
- polarisator
- polarizer
- polariser
- filtr polaryzacyjny
- filtr POL
- circular polariser
- CPL Filter
- POL filter
- polarisations Filter
- polarization Filter
- analizator
- analisator
- Analysator
- POL analizer
- polarization analyser

Unfortunately, I do not know the model of the EPI reflected light illuminator these sliders fit. Fortunately, Mr Thomas Woitzik has photos of an Olympus BH2 BHS microscope with exactly this EPI equipment on the pages of his excellent online shop: https://www.mikroskop-online.de/mikroskope/verkauf/gebrauchte-mikroskope/auflichtmikroskope/olympus-bh2-mit-auflicht-hellfeld-auflichtpolarisation-photoausgang-und-durchlichtmoeglichkeit/

for inverted and upright biological microscopes, made in Japan.

Basic objective parameters:
Manufacturer: Nikon, Japan
Model: Ph3 40 DL 0.55 LWD 160/0-2
Magnification: 40x
Numerical aperture (N.A.): 0.55
Optical correction: achromat
Phase contrast: Ph3 DL - Ph3 indicates the size of the phase ring (requires a matching Ph3 annulus in the condenser), DL (Dark Low) means dark, i.e. positive phase contrast - the object appears darker than the background
Working distance (WD): ~2.1 - 2.5 mm - LWD (Long Working Distance)
Correction collar: compensates for cover glass or vessel bottom thickness in the range 0 - 2.0 mm
Cover glass: the objective can be used without a cover glass, with a standard cover glass approx. 0.17 mm thick, and also with specimens observed through the bottom of a Petri dish up to 2.0 mm thick
Immersion: no (dry objective)
Tube length: 160 mm
Parfocal length: 45 mm
Thread: RMS
Optics: CF (Nikon CF-160) - requires no compensating eyepiece and allows photography by direct projection

This objective is suitable for:
- inverted microscopes - observation through the bottom of a Petri dish or cell culture flask
- upright biological microscopes - observation of specimens with or without a cover glass

Phase contrast work requires a compatible phase contrast condenser or a slider with a phase contrast annulus.

Commonly used, inexpensive cover glasses are 0.17 mm thick mainly in theory. Even the standard for class #1.5 allows a range of 0.16 - 0.19 mm, and in cheap Chinese cover glasses you will find in practice pieces from approx. 0.13 to 0.25 mm, often not matching the thickness stated on the box. Only #1.5H (high precision) cover glasses have a guaranteed thickness of 0.170 mm with a tolerance of +/- 0.005 mm. Variation in cover glass thickness clearly degrades image contrast and resolution (spherical aberration). The correction collar fitted to the objective offered here lets you adjust the optics to the combined thickness of the cover glass and the medium layer beneath it. This compensates for most of the variation found in practice.

In addition, the correction collar of this objective can be set to "0" for work without a cover glass, or to large values (up to 2.0 mm) to adapt the optics to observation through a microscope slide (0.8 - 1.2 mm), a glass Petri dish (usually 1.5 - 2.0 mm - thicker dishes are outside the collar range) or a plastic Petri dish (usually approx. 1 mm, in the range 0.8 - 1.2 mm).

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and uses objectives for 160 mm tube length with a parfocal length of 33, 37 or 45 mm. Some example microscopes are listed in the "compatibility" section, but the list is not complete.

Since the adapter has an empty barrel with an internal diameter of 23.2 mm on the output side, a projection eyepiece of that diameter can be placed in it, or a so-called "USB eyepiece", that is a digital microscope camera. Adapters between the 23.2 mm barrel and the M42 thread are also widely available, and from the M42 thread you can move on to any other mount: Nikon, Canon, Sony and others.

Such a tube can be mounted directly on the microscope body instead of the head. A dovetail seat with a diameter of 41.0 - 41.5 mm is found, among others, on the microscopes:
- Carl Zeiss Jena
- LOMO
- Meopta
- IOR
- Reichert Biopan
- Olympus CH

It is also often used in microscopes with a slightly larger seat, among others Zeiss West Germany, Leitz Wetzlar, PZO, Will Wetzlar, Hund Wetzlar.

The adapter can equally well be fitted onto trinocular heads, as many of them have a seat prepared for it, among others:
- the output in the trinocular tubes of the Carl Zeiss Jena Jenamed, Jenaval, Jenalumar, Jenatech, Jenavert, Jenapol microscopes
- the LOMO TRN-1 heads (ЛОМО ТРН-1), found in the LOMO Polam microscopes
- some versions of the intermediate photo tubes for the Carl Zeiss Jena Mikroval series microscopes (others require a tube screwed onto a thread)

This is not a "tube for one specific microscope model". A trinocular head can be mounted not only on the microscope it was sold with - it is therefore correct to assume that this is a universal tube, with a 41 mm dovetail on one side and a 23.2 mm barrel on the other.

The "compatibility" section gives an example list of microscopes this tube fits, although it is not a complete list.

Description of this part for the microscope.

The tube allows a camera or a camera body to be attached to a trinocular head or directly to the microscope body, even when there is no trinocular head.

Basic technical parameters of this tube:
Manufacturer: LOMO (ЛОМО)
Colour: black, rings and barrel chrome-plated
Tilt angle: none, this is a straight tube
Internal optics: none - not even a deflecting prism
Mounting to the trinocular head or microscope body: ring dovetail (male part)
Dovetail diameter: 41 mm
Type of connection at the output: empty tube / barrel
Tube diameter at the output: 23.2 mm internal diameter
Length of the barrel / tube: variable
Length adjustment: yes - the barrel is extendable, with a scale from 140 to 200 mm and a knurled locking ring

This is the version with adjustable tube length. A scale from 140 to 200 mm is engraved on the extendable barrel, with a reference line and intermediate divisions, and the setting is locked with a knurled ring. This gives two things at once. First, a continuous change of the image scale - the longer the tube, the larger the image falling on the sensor or the film, so the framing can be adjusted without changing the objective. Second, and more importantly, the ability to work with objectives computed for different optical tube lengths: 160, 170, 180, 190 and 200 mm. Carl Zeiss Jena and LOMO objectives are computed for 160 mm, Leitz Wetzlar for 170 mm, some objectives of metallurgical and measuring microscopes for 190 or 200 mm - here you simply set the barrel to the right value and the objective works under its design conditions, instead of delivering an image with residual aberration.

Since the adapter has an empty barrel with an internal diameter of 23.2 mm on the output side, a projection eyepiece of that diameter can be placed in it, or a so-called "USB eyepiece", that is a digital microscope camera. Adapters between the 23.2 mm barrel and the M42 thread are also widely available, and from the M42 thread you can move on to any other mount: Nikon, Canon, Sony and others.
