Product Details

Evenly Ground First Surface for Even Diffusion
Low Index of Refraction Maximizes Throughput
Broad Transmission Range

IR Calcium Fluoride (CaF₂) Diffusers feature an evenly fine ground first surface to produce even diffusion in the visible (VIS) and infrared (IR) spectra. With a wide transmission range up to 7000nm, these diffusers can be used with a variety of coherent and incoherent light sources. The low index of refraction of calcium fluoride maximizes the throughput of these diffusers without use of an antireflection (AR) coating. IR Calcium Fluoride (CaF₂) Diffusers are ideal for use in laser calibration systems and general diffusion of VIS - IR light sources.
