25mm Dia., 3mm Thick, Calcium Fluoride (CaF 2 ) Diffuser

Product Details Evenly Ground First Surface for Even Diffusion Options for 600nm-12000nm (ZnSe) and 300nm-7000nm CaF 2 Broad Transmission Range IR Diffusers feature an evenly fine ground first surface to produce even diffusion in the visible (VIS) and infrared (IR) spectra. Available in both ZnSe and CaF2 options with transmission ranges of 600nm-12000nm and 300nm-7000nm respectively, 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 Diffusers are ideal for use in laser calibration systems and general diffusion of VIS – IR light sources. Specifications General Type: IR Diffuser Note: Fine Grind first surface with a roughness (Ra) of ∼0.75 microns Physical & Mechanical Properties Diameter (mm): 25.00 +0.00/-0.10 Edges: Fine Ground Thickness (mm): 3.00 ±0.10 Optical Properties Coating: Uncoated Substrate: Many glass manufacturers offer the same material characteristics under different trade names.
