VARIOUS FILTER TYPES AND KEY SPECIFICATIONS
Various Filter Types and Key SpecificationsIn principle, optical filters can be divided into several types, and these different types of optical filters are introduced below.1. Absorption filter: The absorption filter is made by mixing special dyes into resin or glass materials. According to the abiRead more -
Calcium fluoride has
Calcium fluoride has the characteristics of wide transmission spectrum range (180nm-8.0μm), high damage threshold, low fluorescence, high uniformity, etc. It is physically soft and easy to scratch on the surface. It is often used in laser collimation and is used as the substrate of various opticalRead more -
Plano-concave lenses
Plano-concave lenses convert a beam of parallel light into divergent light, which is reversely focused at the virtual focus of the plano-concave lens. The focal length is negative, one side is flat and the other side is concave. Plano-concave lenses can diverge a collimated beam from the virtual focRead more -
HOW XIEYI CRYOCHILLER WORKS IN VACUUM COATING TO IMPROVE YIELD
The use of Polycold to trap water vapor is a concept developed by Dale Meissner in the 1970s as a way to speed up vacuum chamber evacuation and reduce base pressure to enhance vacuum coating. In an evacuation system, you can remove gas molecules from the chamber or, in the case of water vapor, changRead more -
OPTICAL SYSTEM ASSEMBLY
Optical System AssemblyOptical systems consist of a wide variety of products and optical components. Optical assemblies feature a variety of individual parts as well as kits to address standard laser or optical requirements such as beam manipulation, focusing, mounting and alignment. When designingRead more -
K9 HIGH PRECISION WEDGE WINDOW
K9 High Precision Wedge WindowThe two planes of K9 High Precision Wedge Windows have an included angle of 30 arc minutes. Two non-parallel planes can avoid the interference effect (Etalon effect) caused by the reflected light on the front and rear surfaces of the high-parallel window, and also avoidRead more -

Zinc Selenide (ZnSe) Double Convex Lenses
Zinc Selenide (ZnSe) Double Convex Lenses are double convex lenses with zinc selenide as the base material.Zinc selenide is a commonly used optical glass material in the infrared band, with a transmission band of 600nm-16μm. It has the characteristics of low absorption and thermal shock resistance.Read more -
Plano Convex
Plano Convex (PCX) Lenses) will focus parallel light into a point, which is the focus of the lens. It is characterized by a positive focal length, one side is flat, and the other side is convex. When in use, the convex side is usually facing the incident light, because the incident light on the twoRead more -
Calcium Fluoride (CaF2) Double Convex Lenses
Calcium Fluoride (CaF2) Double Convex Lenses are double convex lenses with calcium fluoride as the base material.Calcium fluoride has a wide transmission spectrum range (180nm-8.0μm), high damage threshold, low fluorescence, high uniformity, etc. It is physically soft and easy to scratch on the surRead more -
Double Convex Lenses
Double Convex Lenses consist of two convex surfaces with equal radius, which can focus light into a point with a positive focal length. Due to the symmetry of the two sides, it is a more suitable single element in 1:1 imaging applications. It is often used in imaging relay systems and imaging of objRead more -
UV Fused Silica Plano Concave (PCV) Lenses
UV Fused Silica Plano Concave (PCV) Lenses are plano-convex lenses based on fused silica.UV fused silica glass has a wider spectral range (185nm-2.1μm) than K9 optical glass, and has excellent transmittance in the ultraviolet band. It has a lower refractive index, better uniformity, smaller thermalRead more
