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 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 you Stock and Custom Fresnel Lenses, for use within Retinal Imaging in a range of materials such as PMMA Acrylic and Borosilicate. Our Fresnel Lenses consist of a flat surface with interspace concentric steps whereby each step corresponds to the surface of a conventional lenses. PMMA Acrylic is a preferred material type used for retinal imaging Fresnel lenses. The Fresnel lenses are used as part of a system where its multi-focal length provide a multiple in and out of focus image that provide a magnified image of the human eye itself.

Knight Optical has successfully launched a range of Stock Optical Domes for protective housing for Drone and Vision system cameras, where protection of electronic sensor systems and expensive fish-eye lenses from harsh liquid and gas environments is essential. A dome is essentially a window that has two parallel curves faces. Our domes are high quality with good form error polished faces to ensure high clarity and transmission in the Visible and NIR spectrums allowing for accurate measurement. Capabilities: Domes are readily mountable, optically clear and manufactured to a high standard. Available from 5mm to 200mm in diameter and 0.25 to 10mm in thickness offering high transmission and extreme toughness for harsh environments. For more details read the PDF ...

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.

Knight Optical can offer you Stock and Custom Colour Glass Filters, for use within Inline Cameras in a range of materials of brands such as Schott, Kopp and CDGM. Depending on the achievable wavelength and desired affect you need for the Inline Camera we can find a suitable material for your application. Colour Glass Filters are good for selecting a particular wavelength to be absorbed so that the high out of band blocking in achieved. With regards to the use in Inline Cameras, Colour Glass Short pass Filters are more desirable as they cut out the IR wavelengths mean the imaging is not saturated with the IR giving the image better clarity. Colour Glass Filters are polished sheets of special glass that have been cast with a dye. Colour Glass Filters generally are relatively cheap and very stable. The disadvantage with them is that they are only available in a relatively small number of variants, and so can be restrictive in shortwave selection. Read PDF for more Information….

Metallic reflection coatings enhance reflection and are used in many optical instruments for light deflection. We coat glass, metal and plastic. The choice of coating material depends on the reflection requirements in the defined wavelength range. We use aluminium, gold, silver and chromenickel, either with or without protection coating for the VIS, UV and IR ranges.

At Befort, spherical precision optics pass through the hands of qualified specialists. They work with a sure instinct and stateoftheart technology. The machine processing of each surface is done on CNC grinding and polishing machines. We produce spherical precision lenses from optical glass, quartz glass and radiationresistant materials with diameters from 3 mm to 130 mm and a curvature radius from 1.18 mm to plane. We make individual lens elements, achromatic systems, concave mirrors, cylinder lenses and other precisely fitting glass geometries to suit your specific application.
