Lyot Filter, Birefringent Filter, Birefringent Tuners

Overview:

A Lyot Filter (Birefringent Filter), named for its inventor Bernard Lyot, is a type of optical filter that uses birefringence to produce a narrow passband of transmitted wavelengths. Lyot filters are often used in astronomy, particularly for solar astronomy.

Lyot filters (Birefringent tuners) for wavelength tuning of lasers are made of crystal quartz (Transmission ranges: 200 nm-2700 nm) or MgF2 (Transmission ranges: 150 nm-6000 nm) and their optical axis can be parallel to the surface plane or at customized angle.

A Lyot filter is made from one or more birefringent plates (usually quartz), with (in multi-plate filters) each plate being half the thickness of the previous one. Standard thicknesses ranging from 0.5 mm to 10 mm and diameter of 12.7mm(1/2 inch) and 25.4 mm (1 inch) are available from stock. Star Optic offers both uncoated and AR-coated birefringent filters. These can be used at Brewster angle Lyot filter configuration (no Fresnel reflection losses), or in a customer-specific design.
