This is description of this part:
Complete clear glass ring insert with retaining ring – without a printed diaphragm (the original coating has been removed) – for Carl Zeiss (West Germany) phase contrast condensers.
Basic parameters of this clear glass insert:
Manufacturer: Carl Zeiss (Oberkochen, West Germany)
Material: glass mounted in a metal retaining ring with flange
Outside diameter of the retaining ring: 22 mm
Diameter of the clear glass disc: 16 mm
Height of the retaining ring: 3.5 mm
Below are some example applications for this clear glass blank. It can be printed or fitted with, among others:
- a phase annulus or darkfield annulus matching the original one that was installed in the condenser but has become damaged
- an annulus missing from the condenser
- coloured Rheinberg rings
- oblique illumination diaphragms producing a DIC-like effect
- a Hoffmann modulation contrast pattern
- phase annuli for objectives made by other manufacturers, for example Carl Zeiss Jena PhV
- any completely custom DIY design
This particular clear glass ring insert was removed from a fluorescence phase contrast condenser — an older version of the Zeiss condenser P/N 46 52 78. Before installing it in your condenser, carefully compare the shape of its housing and the dimensions of the retaining ring.
Interchangeable diaphragm carriers (whether for phase contrast or, for example, darkfield) make it possible to configure a phase contrast condenser exactly as required. This allows the condenser to support precisely the observation techniques and microscope objectives needed.
The clear glass blank presented here is not a component intended for any specific microscope model. Instead, it is used to upgrade or repair a microscope phase contrast condenser. Likewise, it is not dedicated to any specific condenser model. Many Carl Zeiss condenser models have a suitable opening into which this complete insert can be fitted and customised with your own pattern.
The last photograph in the gallery shows the turret disc of a Zeiss phase contrast condenser. An arrow indicates the clear glass ring insert offered here, already installed.
