Polar Guard Module

Preserves Light Polarization

Raman and fluorescence spectroscopy, interferometry or quantum optics often require a well-defined polarization state of the incident light, which can be distorted by optical components such as mirrors or beam splitters. Until now, correcting these wavelength-dependent distortions has required considerable effort, typically using active systems.

The brand new, patented Polar Guard module preserves the light’s polarization state in a simple and efficient way. It automatically compensates for unwanted distortions and requires only conventional passive optical components such as mirrors, dichroic filters, beamsplitters which are mounted into the module.
