![]() Lasers, Optics, Electronics. Made in Germany. ALPHALAS GmbHBertha-von-Suttner-Str. 5 37085 Göttingen Germany | ![]() Lyot (birefringent) filters made of crystal quartz for wavelength tuning of lasers or use as spectral selection devices with standard thicknesses ranging from 0.5 mm to 10 mm and diameter 25.4 mm (1 inch) are available from stock. The transmission range for quartz plates is 200 nm … 2700 nm, and optionally made of MgF2 Lyot filters cover the spectral range 150 nm … 6000 nm. Both uncoated or optionally AR-coated can be provided. Use at Brewster angle avoids Fresnel reflection losses. Customer-specific designs are available on request. Product-specific web page |
