Newport's UV grade fused silica precision plano-concave lenses are designed to meet the demanding requirements of laser electro-optic applications. These lenses are polished to tight tolerances using master test plates to ensure minimum wavefront distortion. Tight surface quality tolerances minimize scatter and unwanted diffraction effects.UV grade fused silica provides maximum transmission from 1952100 nm. It will not fluoresce under UV light and is resistant to radiation. And for high-energy applications, the extreme purity of fused silica eliminates microscopic defect sites that could lead to laser damage.Standard diameters from 6.35 mm to 50.8 mm allow for quick, easy mounting in many Newport holders when building experiments or prototypes.Standard focal lengths provide a systematic approach allowing lenses of different sizes to be interchanged. These singlet lenses are available either uncoated or multi-layer antireflection coated with a choice of broadband coatings or a laser line V-coating for 1064 nm.
Antireflection coating specifications can be found on Broadband Multilayer Antireflection Coatings and Laser Line Antireflection V-Coatings.
