Knight Optical can offer Hot Mirrors for use in Heat-Sensitive Systems. We supply a range of hot mirrors for a variety of applications – all individually QA checked and metrology tested for quality to ensure parts meet customers’ specs. What’s more, our Hot Mirrors are 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 working with Heat-Sensitive Systems. Hot Mirrors are designed to transmit visible wavelengths and to reflect heat, causing infrared wavelengths. Hot mirrors have a sharp cut-off between Infrared (IR) and visible because they have a dielectric coating that can be controlled for different AOIs (most commonly 0°). For systems that require heat shielding while still needing visibility, hot mirrors can be used. These can attenuate IR radiation and allow visible light, which permits your temperature-sensitive equipment to be visible.

Precision grade plate beam splitters offer higher flatness and parallel specifications particularly useful in laser and imaging applications. Both faces of these precision beamsplitters are polished to a high degree of flatness of λ/4 and have excellent surface quality. Precision splitters are made from high quality optically polished BK7 with both surfaces controlled to a high degree of parallelism. Our stock ranges of precision beamsplitters are available for use in Visible, Near Infrared and Telecoms wavelengths with 50/50 split ratio. The beamsplitter coating is a high quality dielectric coating, the non-splitting face of the beamsplitter is multilayer antireflective coated to eliminate second face ghosting effects.

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 …..

Due to high intensity light from the laser, mirrors used with a laser application require a high damage threshold, and high reflectivity. Knight Optical can help! Laser mirrors are used to reflect or redirect the laser. This manipulation of the beam means it is great for laser applications where there is limited space, as the beam can be steered multiple times. We manufacture mirrors used in the UV/VIS/NIR and infrared. We provide a number of mirrors from stock with coatings at infrared wavelengths such as: Dielectric (98% NIR) Protected Silver (96% VIS/NIR) Protected Gold (97%@750-FAR IR) These are available to purchase from stock in a wide ranges of sizes from 6.3 mm in diameter to a 300mm x 300mm square and various different thicknesses. They are also available with varying flatness specifications with λ/10 also available for immediate shipment and for you to achieve the highest performance. 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.

Knight Optical can supply you with a custom made Diamond turned aspheric lenses for use within Thermal Imaging Cameras. We supply a range of diamond turned 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. 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, Read PDF for more information…

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
