Carl Zeiss Jena Mikrotar 3cm Achr.3 microscope Lumipan Nf Amplival NU pancratic condenser lens

The name of this microscope part.

Mikrotar 3cm Achr.3 lens for Carl Zeiss Jena pancratic condenser (Lumipan, Nf, Nu, Amplival microscope)

Description of this part for the microscope.

Upper lens for low-power objectives for the Carl Zeiss Jena pancratic condenser.

The Carl Zeiss Jena pancratic condenser is a triple condenser with the following ...

lenses:
- N.A. 0.3 for low-power objectives (this is the lens offered here)
- N.A. up to 1.4 (variable aperture) for high resolution and magnification
- oil dark field lens (cardioid condenser)

This condenser is used in Carl Zeiss Jena microscopes:
- Nf
- Nu / Nu2
- Lumipan
- Amplival (gray condenser)

but can also be mounted in the following microscopes:
- Jenaval
- Jenalumar
- Lu (I'm not sure)
- Ng

The companies IOR Bucuresti and Lomo made their own versions of pancratic condensers - I don't know if this lens is compatible with them.

Carl Zeiss Jena Jenaval / Jenalumar microscope field diaphragm lens on metal plate

The name of this microscope part.

Carl Zeiss Jena Jenaval / Jenalumar microscope field diaphragm lens on metal plate

Description of this part for the microscope.

Field lens for Carl Zeiss Jena Jenaval, Jenalumar and Jenavert microscopes.

This field lens is mounted on a suitably profiled metal element that is screwed to the ...

microscope base. This metal element (in which the lens is mounted) also serves as a rail onto which the interchangeable filter holder slides (like this one: https://www.microscopeparts.eu/part/99383, this one: https://www.microscopeparts.eu/part/99404 or the one with a polarizer).

This element is used in the following microscopes:
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenavert

Cast and die-cast metal parts made by Carl Zeiss Jena carry their own numbers. This part bears the number 2648 (full marking: 2648 Si10 CZ).

In the last photos of the gallery, an arrow shows exactly where this element sits in the microscope, so you can identify it without any doubt.

Carl Zeiss Jena Jenaval / Jenalumar microscope second collector lens from microscope base

The name of this microscope part.

Carl Zeiss Jena Jenaval / Jenalumar microscope second collector lens from microscope base

Description of this part for the microscope.

Second collector lens of the Koehler transmitted-light illumination for the base of Carl Zeiss Jena Jenaval / Jenalumar microscopes.

The base of Carl Zeiss Jena ...

Jenaval and Jenalumar microscopes (and of Carl Zeiss Jena Jenavert microscopes, if they are equipped for transmitted light) holds a set of lenses that collimate the light beam. Together they form the Koehler illumination collector, even though they are not mechanically connected to each other.

Here I present a module consisting of:
- the second collector lens in the sequence
- the metal mount holding the lens
- the screws for fastening the mount with the lens to the microscope base

The last photos in the gallery show the complete base of a Carl Zeiss Jena Jenaval microscope. An arrow indicates which part this is and exactly where it sits, so the part can be identified unambiguously.

This lens in its mount fits the bases of the following microscope models:
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenavert

Note - Carl Zeiss Jena Jenavert microscopes come in two versions: reflected light (EPI) only, and reflected (EPI) plus transmitted light. The lens presented here fits both versions, but in the version without transmitted light... it simply has nothing to do :)

This is a service part for anyone who needs to replace this particular part in their microscope. It is not a complete illumination collector.
