This is description of this part:
Intermediate tube with trinocular/photo port, objective nosepiece dovetail mount, Bertrand lens and POL analyzer slot for the Reichert Zetopan microscope.
This is the intermediate tube, forming the main optical module of the microscope. It is mounted onto the microscope stand, while the binocular viewing head is then attached to the top of this intermediate tube. The module incorporates the following components:
- a third optical path (photo port), which is why this module is sometimes referred to as a trinocular unit
- a Bertrand lens (indicating that this is the newer version of this intermediate tube), with a control knob for inserting the lens into the optical path
- a dovetail mount for the objective nosepiece together with a clamping screw for securing the nosepiece
- slots for sliding inserts, including a polarizing analyzer
In addition, the entire module rotates smoothly. Because of its complex mechanical and optical design, it is a component in which individual internal parts may occasionally become damaged.
Information from the manufacturer's English-language catalogue "Zetopan Research Microscope. Price List, Effective December 1, 1976":
- This component belongs to the microscope stand. The catalogue number of the stand is: 9 90 00 01
- English name of this component: swing-out tube carrier, deviating prism for observation and photomicrography, swing-out Bertrand lens
Over the years, Reichert manufactured Zetopan microscopes in three different colours: black, silver and cream. The intermediate tube offered here is the silver version. The different versions differ only in colour and can be exchanged between Reichert Zetopan microscopes. This means that this silver intermediate tube can be fitted to a black Zetopan microscope, although the colour combination may not be aesthetically pleasing.
What is this part needed for?
- as a replacement part for repairing a Reichert Zetopan microscope by replacing the entire damaged intermediate fototubus assembly
- if you have a Reichert Zetopan microscope in which this module still functions but is in very poor condition
- if one of the components of the intermediate tube has been damaged
