10Q20NC.2
€ 519.00

Description

The 10Q20NC.2 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 660 to 1000 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.
