Description of this part for the microscope.

33 mm
Thread: RMS
Variant: glossy housing

This very old series of objectives was used in vintage MinO, M-100, and early versions of the MET-3 microscopes.

Together with the 12mm RMS extension adapter, this lens can be successfully used on newer PZO microscopes such as the MB-30, Studar, and Biolar.

Important: this lens can, of course, be used on microscopes from other manufacturers, as it has a classic RMS connection.

mm
Focal Length: 33 mm
Cover Glass: 0.17 mm
Immersion: no
Thread: RMS

It can be used with any microscope from any manufacturer. Of course, the microscope must be compatible, i.e. support RMS objectives, TL=160 mm, FL=33 mm.

After installing the 12 mm adapter, this objective lens will have FL = 45 mm.

eyepieces can be used with microscopes from any manufacturer, as long as the microscope supports eyepieces with a mounting diameter of 23.2 mm.

socket

This is an external electric illuminator for older type microscopes that use a mirror as a light source.

Mirror microscopes may have the mirror mounted vertically or horizontally, and this lamp (this illuminator) is compatible with both mounting types, as it has two mounting pins.

Note that this illuminator uses bulbs with a standard E14 socket, so an LED bulb can also be installed.

The PZO LM-2 illuminator has a place for a round filter with a diameter of 32 mm. Typically, the following are placed there:
- a diffuser to achieve uniform illumination
- a blue filter to convert the yellow, warm bulb light into a more white (cool) light
- or a blue diffuser to achieve both effects at the same time

Note - the PZO LM-2 illuminator is a so-called "simple" illuminator and does not allow achieving Koehler illumination. An external microscope lamp operating in the Koehler standard is called PZO LMK.

This is a universal microscope lamp and can be used with microscopes from many manufacturers.

Poland
- Model: 5/0.15 160/-
- Alternative model marking: 5/0.15 160/0
- Magnification: 5x
- Numerical aperture N.A.: 0.15
- Correction: achromatic
- Focal length FL: 33 mm
- Tube length: 160 mm
- Cover glass: not required, but may be used
- Immersion: no (dry objective)
- Thread: RMS

This model has a metal housing with no lens at its end. Additionally, this housing can be unscrewed without affecting the operation of the objective - resulting in a relatively large working distance of more than 20 mm.

Three features:
- large working distance exceeding 20 mm
- exceptionally high numerical aperture N.A. of 0.15
- achromatic correction allowing direct projection use
make this relatively uncommon model very frequently chosen for macro photography using a microscope objective connected to a camera (focus stacking).

The fact that this objective has FL = 33 mm allows it to be used with microscopes from other manufacturers, including:
- Lomo Biolam
- Lomo MBB-1A
- Carl Zeiss Jena LG / Lu / Lumipan
- Carl Zeiss Jena Nf
- Olympus CH

Note! Please note that the FL = 33 mm focal length means that this objective DOES NOT FIT the following microscopes:
- PZO Biolar
- PZO Studar

Early versions of this objective (with low serial numbers) have the engraved marking 5/0.15 160/0 suggesting that the objective is intended for use without a cover glass. This is true, but more precisely this objective can work both without a cover glass and with one. In newer versions the engraving already reads 5/0.15 160/- where this "minus" already means "indifferent".

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.

For PZO objectives, it can accommodate all standard achromatic objectives as well as all phase contrast objectives. Some unusual PZO microscope objectives do not fit inside, for example the 100x PI objective (with a red ring).

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 PZO logo on its cap. Caps may be black, white, or grey.

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