Knight Optical can offer Precision Grade Aspheric Lenses for use within Optical Systems. We supply a range of Precision Grade Aspheric lenses for a range of applications – all individually QA checked, and metrology tested for quality to ensure parts meet customer specification. What’s more, our Precision Grade Aspheric Lenses are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to numerous customers with optical systems. Aspheric lenses are used to correct spherical aberrations and can be as effective as a multi-lens system while taking up less physical space; therefore, reducing weight and cost. As such, these lenses are often used in military applications, such as night-vision goggles or missile guidance systems Please read PDF for more Information ….

Our precision grade N-BK7 windows are often used to seal optical enclosures & act as a protective window for the optical and electrical component behind the window, particularly within CCTV and ANPR systems where there is a risk of damage. N-BK7 provides excellent transmission in the visible and near infrared spectrum which can be enhanced still with our Anti Reflective coatings. Our stock range of ¼ wave N-BK7 or equivalent windows are supplied either uncoated or with the option of an Anti-Reflective coating on both faces with extended BBAR for visible and NIR applications within the 450-900nm wavelength range. We can also offer custom solutions for your application, whether it is a custom size or a coating to optimise a different wavelength range, beamsplitter coated or mirror coated to meet your bespoke requirements.

Knight Optical offer a range of Stock Sapphire Windows, and custom for use within Airborne LiDAR Systems. These are systems used in surveying for topographical measurements. The data accumulated can be used to generate a Digital Terrain Model or a Digital Elevation Model which are 3D representations of terrain. Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm. Making it ideal as a protective window for airborne systems which may be utilised in harsh environment or against birds! Sapphire is grown by various methods from seed samples. Sapphire can be polished to a high standard, but as it is the second hardest mineral on Earth it must be subject to high forces to polish. Therefore, windows made from Sapphire must have a thickness to diameter ratio of at least 10:1, that is, greater For more information read PDF….

These dispersing equilateral dispersing prisms have a very simple triangular cross section. Equilateral dispersion prisms are commonly used for wavelength separations, i.e. refracting white light into a rainbow pattern effect. Depending on the material used equilateral dispersion prisms can be used over a wide range of wavelengths. We offer UV Fused silica prisms for use in the ultra-violet wavelength from 170nm and other high index materials which are used for visible applications. Antireflective coatings are applied to most of our high index grade of equilateral dispersion prisms as high index material is sceptical to staining and corrosion which anti-reflective coatings eliminate. Antireflective coatings also help to improve output of the light as they prevent light loss due to surface reflection. The exit beam is in general at an angle to the input beam, this angle depending on the prism material, the wavelength and the incidence angle READ PDF FOR MORE INFO

CMOS sensors are used within commercial grade Digital SLR cameras as a replacement for the more expensive CCD. These CMOS sensors are extremely sensitive to IR light, which can lead to discolouration. IR cut filters are used to block the IR light, meaning that photographs are taken with life-like colours. Colour Glass Filters can be used in variations of Bandpass, Long pass and Short pass, depending on which wavelengths of light need to be blocked resulting in different key areas being more easily distinguished. Knight Optical offers Colour Glass and IR cut filters for such an application, with a wide range of band widths and cut on/off wavelengths. As above these are available as Bandpass, Long pass or Short pass filters and we can also offer customised filters with coatings specific to the wavelength of your choice. We hold a massive inventory of IR cut, Bandpass, Long Pass and Short Pass filters: Read PDF for more info….
