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 has successfully launched a range of Stock Optical Domes for protective housing for Drone and Vision system cameras, where protection of electronic sensor systems and expensive fish-eye lenses from harsh liquid and gas environments is essential. A dome is essentially a window that has two parallel curves faces. Our domes are high quality with good form error polished faces to ensure high clarity and transmission in the Visible and NIR spectrums allowing for accurate measurement. Capabilities: Domes are readily mountable, optically clear and manufactured to a high standard. Available from 5mm to 200mm in diameter and 0.25 to 10mm in thickness offering high transmission and extreme toughness for harsh environments. For more details read the PDF ...

Knight Optical can offer Fire-Polished Aspheric Lenses for use within Optical Systems. We supply a range of Fire-Polished Aspheric 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 with Optical systems. Aspheric lenses are used to correct for spherical aberrations and can be as effective a multi-lens system while taking up less physical space and reducing weight and cost. As such these lenses are often used in military applications, such as night vision goggles or missile guidance systems For more information read PDF …..

Diamond turning is an Aspherics best friend! Knight Optical can supply you with a custom made Diamond turned aspheric lenses. Diamond turned aspheric optical lenses are typically used in missile guidance systems, night vision/thermal Imaging cameras and other military based optics and commercial infrared systems (IR). The benefit of Diamond Turned Aspheric optics, 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 of infrared materials including Germanium (Ge), Calcium Fluoride (CaF₂), Zinc Sulphide (ZnS), Zinc Selenide (ZnSe), Aluminium (Al) and chalcogenide glasses like AMTIR (Ge33As12Se55 ).
