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.
Preserve the polarization state in your complex optical systems
Simply place the depolarizing elements of your optical system into our module and preserve the polarization state across any optical component. Our module easily adapts to the geometry of your system, even in very tight spaces.
