Polarization components are used to separate a beam of light into its orthogonal polarization states for isolation or routing. Our catalog includes both cube and plate polarizers designed to perform under a range of operating conditions, including high power, broad bandwidth, low dispersion, and high extinction. This is achieved using ion beam sputtered and e-beam dielectric coatings, some capable of greater than 1000:1 extinction ratio. When combined with our precision manufacturing, they result in laser quality plate polarizers with better than λ/8 transmitted wavefront error, and 10 – 5 surface quality.
