Precision Custom Heat Filters

Knight Optical can offer KG1 Filters for use in Heat Sensitive Systems. We supply a range of KG1 Filters for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers in Heat Sensitive Systems. KG1 Filters are designed to transmit visible wavelengths to absorb heat causing infrared wavelengths preventing it from reaching your system. Care has to be taken in the design of systems using KG1 as the material is an absorptive blocker and will heat up with use. To help alleviate the heating issue, our KG1 filters are thermally toughened For more information read PDF …..

Knight Optical can offer Custom Homogenizing Rods for use within Electrical Instruments. Electrical instruments use backlight displays to help illuminate and evenly distribute the light source. They can be used as mixers, which is when you want to mix colours from multi-colour LEDs together. The light source will enter a light pipe at a variety of incident angles, which is designed to utilise its total internal reflection to help transmit light from the entrance of the light pipe to the exit. The material’s refractive index is the only factor which affects the light pipe’s critical angle; this defines the angle of acceptance at which the total internal reflection will occur.

Diamond turning is an Aspherics best friend! Knight Optical can offer custom made Diamond turned aspheric lenses for use in missile guidance systems, night vision/thermal Imaging cameras and other military based and commercial infrared systems. We supply a range of diamond turned germanium aspherics for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. The benefit of Diamond Turned Aspherics, are that lens shapes can be manufactured very accurately without an expensive tooling cost except for the diamond bit; and is cost efficient for small quantities. Which are ideal for use within the Defence and Aerospace Industry. Knight Optical offers diamond turned aspherics from a range Read PDF for full specification…

Knight Optical can offer Lithium Fluoride Lenses for use within UV Applications. We supply a range of lithium fluoride lenses for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers using UV optics such as UV lasers. UV lasers are beneficial in some applications as opposed to longer wavelengths such as infrared or visible light as they do not heat the areas around the target. This allows the laser the cut materials by breaking atomic bonds, rather than melting the material. Due to the large band gap for Lithium fluoride, it’s crystals are more transmittive to short wavelength UV radiation than any other material and are ideal for use in X-Ray monochromators, as for use in VUV, UV, Vis and IR spectrums.
