Precision movements

For additional horizontal movement control, an optional X-Y coupling can be mounted to the microscope. This offers a 60 mm x 60 mm range of motion, and is foot-switch controlled.

You can also easily access a range of filters and diaphragms using a sterilizable knob.

Beam Splitters

Two available splitting ratios can be chosen according to application:

  • 50:50 – for adaptation of stereoscopic observer scopes and/or cameras
  • 30:70 – for adaptation of several cameras

Improve the clarity of your procedures.


Cameras & Video Recording

A broad selection of analog or HD video and still cameras can be mounted onto microscopes.
