Fluoresence free sapphire windows

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 Planoconvex Lenses for use within Optical Systems. We supply a range of Planoconvex 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 with Optical systems. Planoconvex lenses are simple lenses with a plane surface and a convex surface and form a moderate quality image close to the axis. They are generally used as elements within a more complex lens system or optical instrument in imaging systems, collimation, lasers and detectors. For more information read the PDF…

Knight Optical can offer Planoconcave Lenses for use within Optical Systems. We supply a range of Planoconcave 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 with Optical systems. Planoconcave lenses are simple lenses with a plane surface and a concave surface and form a moderate quality image close to the axis. Concave lenses have a broad range of applications including, focussing and control of laser beams, moderate quality imaging and other optical instruments. In a multi-element optical system they reduce the power of the system. Used on their own they form a diverging cone or virtual image. A typical use for concave lenses would be in a beam expander.

Knight Optical can offer Ground Glass Diffusers for use within Photography. We supply a range of Ground Glass Diffusers 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 within photography. Ground Glass Diffusers are used in to diffuse the flash from cameras to prevent photos with harsh light and hard shadows to soften and improve the appeal of the image. Diffusers are also used in lightning systems to prevent glare from computer screens, the manufacture of lightboxes for advertising, viewing x-rays, and other applications.
