Calcium sulphate - Import export

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 ).

We can supply you with a custom made Diamond turned aspheric lenses for use within Thermal Imaging Cameras. Thermal Imaging Cameras work similarly to traditional visible camera systems; while traditional cameras form images using visible light; thermal cameras form images using infrared radiation; operating in wavelengths as long as 14µm. 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 camera system with a better image quality. 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 ) PDF FOR INFO

Flowing screeds are designed to leave a smooth flat surface finish, in most cases flowing screeds allow foot traffic within 24 to 48 hours and can be forced dried after only 7 days, if necessary. Key facts about flowing screed Ideal for domestic projects with underfloor due to its very high thermal conductivity. Up to 2000m2 per day productivity Foot traffic within 24 to 48 hours Joints at 30-40 linear meters Very low shrinkage Minimal cracking Will not curl No reinforcement required Eco friendly calcium sulphate binder Can be forced dried after only 7 days We are approved installers for all the major UK suppliers (Aggregate Industries Highflow, Tarmac Topflow Screed A, Hope Hopeflow Gypscreed, Cemex Supaflo, & Breedon Aggregates Easyflow).
