More about part: Carl Zeiss Jena Ergaval / Amplival microscope condenser holder model MZ (ID: 99695)

Description

Holder for mounting interchangeable microscope condensers for Carl Zeiss Jena microscopes.

This condenser holder is a separate, removable module that can be unscrewed. It is mounted onto the dovetail guide located underneath the microscope stage carrier and secured with a clamping screw.

Carl Zeiss Jena Ergaval microscopes were originally equipped with a condenser attached to the "MO" holder. This holder has a permanently mounted iris diaphragm and wide-field lens, while the condenser itself is screwed into the upper thread. In this configuration, the condenser cannot be exchanged.
The Carl Zeiss Jena Fluoval uses a similar arrangement, whereas the Carl Zeiss Jena Amplival was originally equipped with a panchromatic condenser.

If the user wishes to use other condensers (including those made by manufacturers other than Carl Zeiss Jena), the original condenser holder must be replaced with the MZ condenser holder. Once this has been done, any microscope condenser with a mounting diameter of 39.5 mm can be installed. Condensers with a 37 mm mounting diameter can also be used if they are fitted with a suitable adapter ring.

This is exactly such a holder for interchangeable condensers.

Although this component is grey, it is also compatible with older black Carl Zeiss Jena microscopes from the 1950s and 1960s (it simply will not look completely original unless it is repainted).

The last photograph includes an excerpt from the original manufacturer's documentation. An arrow indicates this exact model of condenser holder, making it easy to identify the component.
