Polarisation maintaining module for optical systems
Discover Our Latest Innovation!
Optical techniques such as Raman spectroscopy, fluorescence or multiphoton microscopy, interferometry or quantum optics require a fine control of the light polarisation state.
Optical elements like mirrors, beam-splitter, dichroic mirror, filters, are most of the time used far from normal incidence, inducing a distortion of the polarization.
This invention solves this problem in a simple and efficient way.

Full correction off active optical element and corner mirrors in reflection and transmission
Preserve beam crossing : can replace any optical element without modification of the original setup
Compact design that can fit to standard microscopes
Works with any optical element like mirrors, dichroic filters, beam-splitters ...
Two elements in cascade on each channel improving filtering effect or allowing working with cheaper optical elements.
