BREXIT UPDATE: Knight Optical will continue to provide quality assured service for all your optical requirements both custom & stock. We will handle all requirements caused by the new regulations.

New Products

Knight Optical is always looking to expand our stock catalogue to ensure we can provide our customers with quick solutions to their optical needs. Below are the latest optical components we have added to our vast range.


 

UV Fused Silica Domes

Knight Optical now stock 50mm and 100mm UV fused silica domes, suitable for the use in UV sterilisation systems and other UV applications due to their impressive transmission range down to below 200nm. UVFS is a durable and chemically stable material, making these domes ideal front optics, which offer a wide field of view with minimal distortion of the lightpath. We can also offer custom dimensions upon request. For more complex domes, such as one with a flange for mounting, we now also offer moulded optical components in two different specialist UV materials.

UV Interference Bandpass Filters

Knight Optical has a new range of interference bandpass filters with centre wavelengths within the ultraviolet waveband, covering all the common UVC light sources including excimer lamps (222nm), mercury lamps (254nm) and UV LEDs (265nm, 273nm and 280nm). We offer mounted and unmounted options, in 12.5mm, 25mm and 35mm diameters. We also offer custom interference filters to suit your specifications.

UV Colour Glass Filters

Our range of UV colour glass filters include bandpass and longpass filters. The bandpass colour glass filters are equivalent to Schott UG1, UG5 and UG11 and all transmit within the UV waveband and block from 400nm. The longpass filters transmit within the UV and visible regions. Colour glass filters are cost effective but, due to the manufacturing process, there are limited variations available.
