Infrared optical window W-FS series

precisionlargeanti-reflective

Windows are used to protect more expensive optical parts from harsh environments or debris. The other task of the window is to transmit radiation with minimum losses. For this reason, protective windows are AR/AR coated for the specific spectral range used in the application. • Material : UVFS, BK7, CaF2, Sapphire • Dimensions tolerance : +0/-0.2 mm (aperture) +/- 0.1 mm (thickness) • Surface quality : 20-10 S-D, 40-20 S-D • Transmitted WFD : λ/10 @ 633 nm • AR/AR coatings : R < 0.2 % *standard specifications
