Knight Optical supply stock and custom deviation penta prisms that cover the visual and NIR range. Deviation prisms are an optical component that will redirect a light beam into another known angle relative to the incoming beam. The penta-prism is a deviation prism which is used in cameras with a movable mirror that bends the beam vertical onto the focus graticule. The penta-prism provides a 90° deviation of the beam from the focus plane and, via an eyepiece, the user can aim the camera along the same axis as the beam that is focused onto the detector, electronic or wet film. Deviations through other angles can be accomplished using, for example, abbe constant deviation, littrow, and wadsworth prisms.

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 Shielding. Infra-red interference Shortpass filters are designed to transmit wavelengths shorter than the “cut-off” of the filter and to block bands above that. In many systems that require heat shielding while still needing visibility a shortpass filter can be used. These can attenuate infrared radiation and allow through visible light, which allows your temperature sensitive equipment to be visible. They can also be paired with a longpass filter to make a bandpass filters. Read PDF for more Information…..

Germanium wafers are a semiconductor material & are for microelectronics - Germanium wafers are a semiconductor material & therefore are a smart choice for microelectronics. Due to its unique electric properties, it is widely used for sensors, solar cells and infrared optical applications. The wafers are also great for microelectronics as the space is limited and being available in 500μm or less it makes it perfect to achieve the high quality results required. It’s thermal conductivity makes it a good alternative to silicon. Our stock wafers are produced as thin as 500μm and provide exceptional surface quality. However, we can manufacture to a fully customised specification with a wafer thickness as little as 10 μm. Typical specifications of our germanium wafers are: 10mm – 150mm in diameter <500μm in thickness Doped and undoped Germanium

Knight Optical can supply you with custom made Diamond turned aspheric lenses for use within autonomous vehicle LiDAR systems. Autonomous vehicle LiDAR systems create driverless cars. Whereby the system produce autonomous vehicles which can perform complex manoeuvers and drive in public with little or no input from a user. Spherical aberration occurs in common singlet lenses, which results in an image that appears distorted, aspheric lenses correct spherical aberration. An aspheric lens surface is designed non-spherical, which allows a single component lens to collimate or focus highly divergent rays potentially replacing a multi-lens system. This in turn provides the LiDAR system with a better signal quality, at lower costs whilst making the system more compact. Knight Optical offers diamond turned aspherics from a range of suitable NIR materials for autonomous vehicle LiDAR including N-BK7 or equivalent, sapphire, quartz, UV fused silica, amongst others.
