Product Description

Our are available uncoated or coated with a variety of multi-layer antireflection coatings. All lenses feature λ/8 surface accuracy and 20-10 scratch-dig surface quality. UV Fused Silica is synthetic amorphous silicon dioxide of extremely high purity providing maximum transmission from 195-2100 nm. This non-crystalline, colorless silica glass combines a very low thermal expansion coefficient with good optical qualities and excellent transmittance in the ultraviolet region. Also, it will not fluoresce under UV light and is resistant to radiation.

Bi-Convex (Double-Convex) lenses have the same radius of curvature on both sides of the lens and function similarly to plano-convex lenses by focusing parallel rays of light to a single point. As a guideline, bi-convex lenses perform with minimum aberration at conjugate ratios between 5:1 and 1:5. (Outside this range, plano-convex lenses are usually more suitable.) Bi-Convex lenses are the best choice when the object and image are at equal or near equal distance from the lens. Not only is spherical aberration minimized, but coma, distortion and chromatic aberration are identically canceled due to the symmetry. UV Fused Silica lenses are ideal for UV or higher energy applications, combining a very low thermal expansion coefficient and excellent transmittance down to 195 nm.
