UV optics

What are you looking for in Stock?

Knight Optical provides a range of high quality optical components optimised for ultraviolet wavelengths for UV applications. In most cases UV grade fused silica is used as a substrate and works efficiently in deep UV at 175nm, achieving 85% transmission at 185nm.

Alternatively, precision UV windows and lenses may be manufactured from quality calcium fluoride crystal, transmitting at over 90% at 185nm at additional cost. Suitable optical materials are always chosen to optimise the design and to meet any reasonable specification. 


 

UV windows are available in calcium fluoride, quartz and UV grade fused silica. These optics are typically used for viewing or protection purposes and can be coated for improved transmission.

UV grade ground glass diffusers are manufactured from UV fused silica with a standard 40μm diffused finish and are used to alter the divergence of incident light.

UV grade plate beamsplitters are used to separate an incident beam into reflected and transmitted parts at a specified ratio. UV antireflection coatings are applied to their rear to eliminate ghosting effects. 

UV optical filters ranging from simple colour glass type though to complex interference bandpass type and a range of UV grade neutral density filters. 

UV lenses are available in various forms, from simple planoconvex types to fibre coupling ball and half ball lenses. UV lenses are typically manufactured from UV fused silica and optimized for UV applications.

UV mirrors are available as plain and concave types with an aluminium/MgF2 coating for use between 180nm to 650nm. 

UV grade optical flats are manufactured from quartz and are available in a range of sizes up to 300mm diameter with a selection of grades.

UV sheet polarisers are made from HNPB material and efficient at 290nm.  Original HNPB material has been discontinued by the manufacturer therefore stock may be limited. Where necessary we can offer equivalent material with near identical properties.

UV prisms are available for a range of dispersing, reflecting and inverting applications.

Knight Optical supply quality stock optics and mechanics made to our exacting specification.  Every component is individually tested by our highly skilled technicians in our state of the art metrology lab to ensure all components meet our high quality standards.
