# Description and specifications:
"Primo" system tube lens (infinity-corrected) for Carl Zeiss Primostar microscopes.

In Zeiss Primostar microscopes the objectives are infinity-corrected, so additional optics in the form of a tube lens are needed to create the intermediate image. In this case it has to be a lens with a focal length of 180 mm, the same as in the Motic CCIS system - and unlike the Zeiss ICS system (also infinity, used among others in the Axio series microscopes), whose tube lens has a focal length of 164.5 mm.

This lens was removed from the Zeiss 415500-1400-000 binocular head, but it also fits the model with a built-in digital camera and the model with a trino port (phototube). So it fits:
- the Zeiss 415500-1400-000 binocular head
- the Zeiss 415500-1401-000 binocular head with trinocular phototube
- the Zeiss 415500-1402-000 binocular head with built-in digital camera

In the Primostar series the tube lens is placed in the two-part microscope head. This head consists of the angled tube and the eyepiece head screwed onto it. The tube lens sits in the lower part of the tube, at the joint with the microscope body, inside the ring dovetail.

# Examples of use
- if this tube lens is missing from the tube of your Zeiss Primostar microscope
- if your tube lens is damaged or in very poor condition, for example when fungus has attacked its anti-reflective coating
- if you want to use Carl Zeiss "Primo" series objectives on microscopes from other manufacturers designed for a tube length other than 180 mm
