NIR Coated UV Fused Silica Plano-Convex Lens

General Introduction: Raytek's 650-1000 nm antireflection coating of UV grade fused silica Plano convex lens is used to meet the stringent requirements of laser electro-optic focusing. The master test plate is polished to achieve tight tolerances to ensure minimum wavefront distortion. Strict surface quality tolerance minimizes scattering and harmful diffraction effects

 

Products Name: NIR Antireflection Coated UV Fused Silica Plano-Convex Lens

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 technology.es

Optional I:	UV fused silica from CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,ETC
Optional II:	Equivalent UV fused silica Made in China, C-laser own brands

 

Raytek Broadband multilayer Near Infrared Antireflection film:

Raytek’s AR.16 broadband antireflection films improve the transmittance of these lenses by reducing surface reflection in the range of 650-1000 nm. The performance of the uncoated surface can be improved by near infrared multilayer antireflection. For 1064 nm, 10 Hz 10ns laser pulse, the damage threshold is 7.5 j/cm2.
