This is description of this part:
Empty double filter wheel for the illuminators (Lampenhaus) of Carl Zeiss Jena Jenalumar microscopes and similar models.
This part fits the lamphouses used on the following microscopes:
- Carl Zeiss Jena Jenaval
- Carl Zeiss Jena Jenalumar
- Carl Zeiss Jena Jenapol
- Carl Zeiss Jena Jenavert
Each of these discs has 5 seats that take filters of 32 mm diameter. The filters are locked in place by a springy retaining ring (a so-called Sprengring) so that they cannot fall out. The set offered here comes with 10 such rings. Since each wheel can be loaded with five filters, the total number of possible combinations is 25.
At the moment these filter seats are empty. Neither wheel has any filters fitted - you are free to load them with whatever filters you like.
This two-wheel module fits halogen, HBO and XBO lamphouses.
Parts made by Carl Zeiss Jena, cast or injection moulded from ZnAl alloy, carry their own numbers by which they can be identified. This double filter revolver module consists of 3 cast components:
- 2672 Si10 CZ - the frame carrying both wheels. It is at the same time the outer cover plate with which the whole module is screwed onto the lamphouse
- 2957 Si10 CZ - the thick filter wheel
- and note: the thin filter wheel also carries the number 2957 Si10 CZ, which is unusual for this manufacturer - that two parts differing in dimensions should share the same number
This double filter wheel is sometimes also called:
- double filter holder
- double filter turret
- dual filter carrier
- double filter slider
- double filter changer
Here https://www.microscopeparts.eu/part/99693 you can see what a complete 6V 25W halogen illuminator looks like with a single filter wheel fitted. The double set offered here fits such an illuminator among others, so the single filter wheel from the illuminator of a Carl Zeiss Jena Jenaval microscope can, for example, be replaced by the double one.
What is this part needed for?
- if you own a Carl Zeiss Jena microscope with an illuminator whose filter wheel is missing
- if your lamphouse holds only a single filter wheel and you want to replace it with a double one
- if there is already a filter wheel in your lamphouse, but you own so many loose filters that you want to load another changer with them and swap whole filter sets quickly
