Description of this part for the microscope.

objectives
- focusing block with knobs and mechanism for fine (micro) and coarse (macro) adjustment

It is very possible that the knobs and mechanism from the focusing block fit other Hertel & Reuss microscope models, such as the CN-fle or Primus, but I have not personally verified this.

Description of this part for the microscope.

a complete coarse focus mechanism (macro movement) and coaxial fine focus mechanism (micro movement)
- a complete base with illuminator holder, field diaphragm and filters
- a complete arm with tube holder and EPI illumination selector switch

See also item no. 99584 in this database – it is a similar microscope body that differs only in a few details.

The complete Zeiss Photomicroscope microscope stand may be useful in the following situations:
- if you are assembling your own microscope and purchasing individual components in order to build a system that fully meets your expectations
- if you own a Zeiss Universal microscope and would like to replace it with a Photomicroscope II model, it is sufficient to replace the stand because the remaining components are compatible
- if you own a Zeiss Photomicroscope microscope but its stand is in very poor condition, damaged or incomplete: it has non-functional vertical movement knobs, a damaged diaphragm, or other mechanical problems

illuminator mount
- the arm containing the coarse focus (macro movement) and coaxial fine focus (micro movement) mechanism
- a pincer holder (single objective holder) for a polarizing microscope objective
- the microscope head mount – however, in Lomo Polam microscopes this position is first occupied by the intermediate tube with the polarization analyzer, and only then by the microscope head

The complete Lomo Polam R-113 / P-113 microscope body may be useful in the following situations:
- if you are building your own microscope by purchasing individual parts to assemble a configuration that fully meets your requirements
- if you own a Lomo Polam microscope but its body is heavily worn, damaged or incomplete, for example with defective coarse/fine focus controls, a damaged pincer objective holder or other mechanical problems

Lomo Polam microscopes are built around a standardized modular design. For example:
- components such as the stage holder, condenser holder, polarizing intermediate tube, monocular head or trinocular photo head from other Polam models (e.g. L-211 or L-213) are compatible with the R-113 / P-113 body
- the R-113 body can also be installed on other, including newer, Lomo Polam models, making it an inexpensive way to repair a microscope with a defective coarse/fine focus mechanism

for the large illuminator attached to the rear of the microscope
- a built-in right-angle mirror in the base that redirects the light beam. This mirror can be centered using two adjustment screws located on the front of the microscope base
- the focusing block with coarse focus (macro movement) and coaxial fine focus (micro movement)
- a mount for either the single objective holder (pincer holder) or the 5-position polarizing objective nosepiece
- the microscope head mounting point – however, in Lomo Polam microscopes a polarizing intermediate tube with the analyzer is mounted here first, followed by the microscope head

The complete body of the Lomo Polam L-211 microscope may be useful in the following situations:
- if you are building your own microscope by purchasing individual components to assemble a configuration that perfectly matches your requirements
- if you own a Lomo Polam microscope whose body is in very poor condition, damaged or incomplete, for example with non-functioning focusing controls, a damaged illuminator mount or other mechanical problems

Since this database includes both the body of the Lomo Polam R-113 (Полам Р-113) and the Lomo Polam L-211 (Полам Л-211), here is a brief summary of the differences between them:
- the Lomo Polam R-113 has no built-in illumination components in the base, only an opening for a mirror or an external light source
- the Lomo Polam L-211 has a built-in right-angle mirror in the base that redirects light from the rear illuminator vertically upward, and it also provides a mounting point for the large rear illuminator
- the Lomo Polam R-113 has a permanently installed single objective holder (pincer holder) for a polarizing objective
- the Lomo Polam L-211, on the other hand, has an interchangeable mount that accepts either a single objective holder (pincer holder) or a 5-position polarizing objective nosepiece

Lomo Polam microscopes feature a standardized modular design, which means, for example:
- components such as the microscope stage holder, condenser holder, polarizing intermediate tube, monocular head or trinocular photo head from other Polam microscope models (e.g. R-113, R-211 or L-213) are compatible with this L-211 body
- this L-211 body can also be installed on other Lomo Polam models, including older ones, making it an inexpensive way to upgrade an older Polam microscope, for example one with a damaged coarse/fine focusing block
- another interesting option is replacing only the base in order to equip simpler Lomo Polam microscopes with the powerful rear-mounted illuminator

An amusing curiosity. Users of Lomo Polam microscopes, especially those unfamiliar with the Cyrillic alphabet, sometimes misread the model designation of the Lomo Polam L-211.
- the original Cyrillic designation is: Л-211
- many users mistake the letter "Л" (L) for the letter "П" (P) because they have a very similar appearance in Cyrillic
- as a result, they incorrectly read the model designation as Lomo Polam P-211
- the funny part is that there actually is a microscope model called "ЛОМО Полам Р-211" – however, the Cyrillic letter "Р" corresponds to the Latin letter "R", which makes the confusion even greater

Description of this part for the microscope.

it is a similar microscope body that differs only in a few details.

This Zeiss Phomi II microscope body includes:
- the coarse and fine focus block together with the focusing knobs
- the base (also called the foot or base) with the rear illuminator port, field diaphragm (iris diaphragm), and built-in filters
- the microscope arm with the intermediate tube mount (dovetail clamp), photographic film compartment, and all knobs and switches

When can a complete microscope body be useful?
- if you are assembling a microscope yourself and selecting every component so that the final configuration is exactly the way you want it
- if you have an older model (for example, a Zeiss Universal without EPI reflected-light capability) – replacing the stand effectively upgrades the microscope, while the remaining components can be transferred because they are compatible between these models
- if your microscope is damaged or in poor condition – in that case, this microscope body simply replaces the damaged part

knobs
- coarse focus mechanism with the rack and control knobs
- microscope base with the rear illuminator port and a decenterable field diaphragm (iris diaphragm)
- stand arm with the microscope head mount and a dovetail guide for the interchangeable objective nosepiece
- dovetail guide with a rack and drive knob, together with the mounting module for a pankratic condenser or a clamp for mounting another condenser.

When can a complete microscope stand be useful?
- if you are building a microscope yourself and selecting every component so that the final configuration is exactly what you need
- if you own an older model (e.g. Carl Zeiss Jena Lg) - replacing the stand acts as an upgrade, while the remaining components are compatible between these models (except for the condenser)
- if your microscope is damaged or in poor condition - in this case the stand simply replaces the damaged microscope component
- if you need to replace only a single component in your damaged microscope (for example the fine focus block or the iris diaphragm), but decide to replace the entire stand instead

Contact us if you are looking for any part to repair a Carl Zeiss Jena Lumipan microscope. Even if the required part is not currently visible in the photographs or has not yet been added to this database as a separate product, it is located inside this complete microscope and is available. Examples include:
- knobs and control knobs
- racks and gears
- guides and shafts
- housing parts
- the iris diaphragm or its individual components
- illumination system components, deflecting mirror
- many other parts, from the complete upper tube down to the smallest screw or spring

The parts listed above are only examples - other components from this microscope stand may also be available.
