Optical Beam Sampler, Broadband, UVFS, 25.4 mm, λ/10, 440-700 nm

The 10Q20NC.1 Broadband Beam Sampler is a 1.0 inch (25.4 mm) diameter, 6.10 mm thick, UV fused silica beam sampler with a λ/10 surface flatness. It is 440-700 nm anti-reflection coated on the back surface. Our broadband beam samplers are designed to split off or sample a beam by Fresnel reflection for beam monitoring applications where minimum disturbance of the transmitted beam is necessary.
