Thin-Film Linear Polarizer, Operating Wavelength Band: 400-1700 nm OPPF1-VIS
JCOPTIX thin-film linear polarizers cover 400-1700 nm for visible and near-infrared polarization applications. A sandwich structure protects an absorptive polarizing film between two UV fused silica windows with antireflection coatings on the air-facing surfaces. Standard aluminum retaining rings or SM lens tubes prevent stress from improper mounting from affecting performance. Two versions are offered: the first operates at 400-700 nm, with T2 (350-700 nm) antireflection coatings at the air-glass interfaces; the second operates at 700-1700 nm, with T6 (700-1700 nm) coatings. Both offer high transmission and extinction ratio within their bands for various low-power laboratory laser applications.
