Uv applications - Import export

Knight Optical can offer Lithium Fluoride Windows for use within UV Applications. We supply a range of lithium fluoride windows for a range of applications. All individually QA checked &metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes & 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.

In order to design machines safely and to meet the requirements of the Machinery Directive 2006/42/EC, safety functions are required in the control systems. Typically, the required Performance Level PLr is determined for each safety function. This is where the first difficulty begins during the planning and commissioning of UV systems, namely determining the severity of the injury, the frequency and duration of exposure, and how to avoid the uv hazard. In the short term, UV exposure of the skin leads to erythema, elastosis and/or skin cancer. In contrast, UV exposure of the eye can lead to photokeratitis, conjunctivitis and cataractogenesis. If e.g. skin cancer is considered, it is a severe, usually irreversible injury. In this context, Directive 2006/25/EC „Artificial Optical Radiation“ allows regular exposure up to a daily exposure limit of 30 J/m².

Knight Optical can offer you stock and custom lambda/10 mirrors for use in Spectromters, in a range of materials such as BK7 or equivalent, Zerodur, Quartz, UV Fused Silica and many more.

Knight Optical can offer UV Fused Silica Lenses for Flame Detection Applications. UV Fused Silica can be used in Flame Detection Applications, due to its high transmission into the NIR range (approximately <92% avg 400-2000nm) meaning that a clear distinction can be made between different wavelengths of light. UV FS also has a very low coefficient of thermal expansion 0.55x10-6K-1 at 300K) compared to N-BK7 (7.1x10-6K-1), meaning that it can still provide optical performance under high temperature. UV FS also has a high melting point compared to N-BK7, providing further protection for your application in high temperature environments. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher. Read PDF for more info

Knight Optical can offer UV Fused Silica Lenses for Solid State Laser applications. UV FS is a prime choice for lenses in use with Solid State Lasers due to its consistently high transmission in the UV/VIS/NIR regions. This means that it can be used with a range of different laser types, such as Titanium-doped sapphire (tuneable to 660-1080nm) or Alexandrite (tuneable to 700-820nm) with very little change in performance. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher. Read PDF for full specification

Sapphire is an incredibly hard crystal (HK1370kg/mm2), second only to diamond. Fluoresence free sapphire windows have high mechanical strength, thermal and chemical resistance and is scratch resistant, making it very desirable for operating in harsh conditions. Sapphire windows can be made thinner than alternative crystals thanks to its structural integrity and can operate up to 2030⁰C. The material transmits between the UV and IR at 0.15-5.5µm, and has a high refractive index of 1.75.. Knight Optical supply a range of quality Sapphire optical components including Fluoresence free sapphire windows, Sapphire lenses, Sapphire prisms, and Sapphire blanks either from stock or bespoke custom made to your specification for a range of applications.  Our current range includes Random Polarization Sapphire that can be used for most applications apart from UV use.

Knight Optical can offer UV Fused Silica Windows for Vacuum Applications. UV Fused Silica is a relatively hard optical glass with a very low coefficient of thermal expansion. This means that it is a good choice for us in Vacuum applications, as any difference in temperature will not affect the optical performance. In addition to the above, UV FS has high transmission from UV to NIR meaning that there is little loss of image when it is used for a Vacuum Window/viewport and therefore the quality of the optical system is not compromised. All our UV Fused Silica Lenses are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Trioptics Optispheric, and Starrett AV300 and Zygo Verifire XPZ. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components Read PDF for more info
