DE1293472C2 - Tube lens system with compensators for polarizing microscopes - Google Patents

Description

Compensators for polarizing microscopes Ocrao to be swiveled in shape so that it is in one

swiveled state neither at the image field grölk

Something different about the remedial relationships. According to the invention, this task is accomplished by

The invention relates to a tube lens system with solves that the lens _elements and optionally ver-compensators for polarization microscopes, between different compensators comprehensive tube lenses whose two lens elements parallel beam system near the exit pupil of the objective exists in the length of which optionally different than Independent component formed objective compensators can be inserted or pivoted on the support piece of the microscope stand is arranged in such a way that they are arranged. that each one of the existing expansion joints

It is known that, in polarization microscopes, _{different types of compensators can be inserted} between the two lens elements or different types of compensators can be pivoted between the objective and *.

These disadvantages do not apply if the compensators are arranged in one of several possible compensators in the parallel beam path. It provided _43.
