simple microscope stages with clips for holding the specimen. Therefore, at magnifications above 400x, manually manipulating the slide with the specimen becomes very difficult. XY cross stages are used for this purpose, for example, to move the specimen very precisely at 500x, 600x od 1000x magnification with oil immersion.

This is not a cheap plastic cross stage - it is a well-made Hertel & Reuss design.

NOTE - if the mounting pin spacing matches, this cross stage can be mounted on stages from virtually any manufacturer.

Note - this is version "A" of the XY cross-stage mechanism - it differs from version "B" only in the shape of the screws, but in order to ensure that my photos always show the original item, each variant is listed separately in the database.

Note - Hertel & Reuss manufactured cross stages with fixed specimen clamps as well as a model with a spring-loaded clamp. Here I present and offer the version with fixed clamps.

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.

Model: 160/0,17 EF 100/1.25 OEL PHACO 3
Magnification: 100x

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).

not intended for so-called "thick" objectives
Thread in the cap: no, the cap of this objective case does not contain a thread for attaching an RMS objective

This objective case can be used to store so-called "short" objectives (DIN 33 mm), longer objectives (DIN 37 mm), and long objectives (DIN 45 mm), provided they are not the so-called "thick" type.

Various names are used on the secondary market for a microscope objective case, including:
- objective case
- microscope objective case
- objective container
- microscope objective container
- objective storage case
- objective storage container
- objective box
- objective storage box
- protective objective case
- objective lens case
- objective lens container
- dust protection case
- transport case for microscope objectives
- microscope objective holder case
- storage canister for microscope objectives

Each case has the Hertel & Reuss logo on its cap.

Although this case is of greatest interest to users and collectors of objectives made by the manufacturer Hertel & Reuss, it can of course be used to store objectives from any manufacturer.

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.

Because this is important, I will write it again: this is a single eyepiece, not a pair of eyepieces.

This is a solution for people who:
- either have a pair of these eyepieces, but one of them needs to be replaced
- or have a microscope with a monocular head

For Will Wetzlar microscopes, eyepieces from practically any manufacturer can be used, provided that they are designed for a finite tube length system and have a mounting diameter of 23.2 mm. However, many users appreciate having original parts.

This eyepiece also works the other way around - it fits almost any microscope from any manufacturer that allows the use of eyepieces with a mounting diameter of 23.2 mm. Users of microscopes from many manufacturers are happy to choose German eyepieces because of their high quality. I have included some examples in the "compatibility" section, but this is definitely not a complete list.

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.
