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.

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.

Knight Optical offer a range of Stock N-BK7 Dome Windows, for use with Underwater Lighting. A dome is an optical window composed of two parallel curved surfaces. Domes are commonly used in defence applications and often in extreme environments such as Submersible ROV’s. The shape of the window creates a naturally strong shape that gets tougher under pressure. Using a curved dome optical surface allows for an increased beam angle, therefore allowing a greater area to be lit from one light source. For visible applications, N-BK7 with its high optical quality and uniform transmission and low absorption in the visible spectrum makes it an ideal material for underwater lighting. A tough and cost effective solution which allows for good transmission of the light source in the underwater environment will both protect the light source as well as transmitting from 300nm up to 2µm.
