Lyot filters are a type of optical
filter that uses birefringence to produce a narrow passband of transmitted wavelengths.
Lyot optical filters have broad and diverse applications, including laser ranging and imaging, and laser communications. Our optical filters offer an unprecented combination of wide field-of-view (±20° along the vertical axis), narrow passband, wavelength flexibility, large aperture, and tunability.
We developed our filter technology in response to a challenging plasma diagnostic application, which was funded by the Department of Energy/OFES. This culminated in the installation of a set of filters at the Princeton Plasma Physics Laboratory which have been operating reliably since 2004.
