Product Description

General Introduction: Raytek's 245-440 nm antireflection coating of UV grade fused silica Plano convex lens is used to meet the stringent requirements of laser electro-optic focusing. These lenses are polished using the master test plate to achieve tight tolerances, ensuring minimal wavefront distortion. Its strict surface quality tolerance minimizes scattering and harmful diffraction effects.

Products Name: UV Antireflection Coated UV Fused Silica Plano-Convex Lens
Alias: UV Coated UV Fused Silica Plano-Convex Lens, UV Fused Silica Plano-Convex Lens, UV Fused Silica Lens, UV Coated Plano-Convex Lens,UV AR Coated Lens, UV lens, UV Plano-convex lens,etc

Lens Substrates:
UV fused silica substrate for UV region, laser line and wide band applications
UV fused silica is a synthetic amorphous silica with high purity, which can provide the maximum transmission from 195 nm to 2100 nm. The amorphous and colorless quartz glass has very low thermal expansion coefficient, good optical properties and excellent transmittance in the ultraviolet region. The transmittance and uniformity are higher than that of crystal quartz, and there is no inherent orientation and temperature instability of crystal form. It does not fluoresce under ultraviolet light and is radiation resistant. For high energy applications, the high purity of fused silica eliminates the micro defects that may cause laser damage. For more information, please refer to the summary of optical materials technologies
