Advanced Polarising Microscope

A robust trinocular polarising microscope designed for advanced transmitted-light examination of birefringent specimens. It is available with either transmitted-light polarisation alone or a combined transmitted and reflected-light configuration for examining both covered and uncovered opaque specimens.

The microscope includes strain-free plan achromatic objectives, FN22 eyepieces, a centreable nosepiece, a large rotating stage, rotating analyser, Bertrand lens and a comprehensive set of compensators.
