Product Description

General Introduction: Raytek's uncoated UV grade fused silica Plano convex lens is used to meet the stringent requirements of laser electro-optic focusing applications. These lenses are polished using the master test plate to achieve tight tolerances to ensure minimum wavefront distortion. Strict surface quality tolerance minimizes both scattering and harmful diffraction effects.

Products Name: Uncoated UV Fused Silica Plano-Convex Lenses
Alias: Uncoated UV Fused Silica Plano-Convex Lenses,Uncoated UV fused silica plano-convex lens, Uncoated fused silica plano-convex lens, Uncoated fused silica 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 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

Advantages of uncoated lens
Uncoated lenses are used in optical systems and equipment, mainly because they have a very wide wavelength range, high damage threshold ratio, and do not need to be coated, so they are always cheaper than coated lenses. In addition, the uncoated lens makes the image in the camera look more "retro", which is becoming more and more popular in cinema film production.
