Reflectionreducing coatings increase the light transmission of optical systems. This is particularly important for the light intensity of multilens optical systems such as objectives. Another benefit of antireflection coatings is their capability to strongly reduce scattered light losses between the lenses. Our product portfolio covers single and multiplelayer antireflection coatings, antireflection coatings for laser applications and coatings for applications in ultraviolet (UV), visual (VIS) and infrared (IR).

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 can offer you the solution for your CCTV Cameras! CCTV Systems use Germanium Windows for their properties which make them ideal for thermal imaging and night vision use. Germanium Material offers excellent transmission across the IR wavelength range. Making it ideal for use within Thermal Imaging Cameras; which are used extensively in CCTV applications. Germanium typically operates in the 2µm to 14µm spectral range; that covers the LWIR (8-12μm) and MWIR (3-5μm) thermal imaging wavelength range. Our Germanium windows are available from stock, custom size and shape with Anti-Reflection coatings on one or both sides, and/or with Hard Carbon Diamond coatings. Custom coatings for Germanium windows available on you request and to your specific requirement with diameters up to 300mm diameters. Read PDF for Info

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

Our Germanium windows are not only used in IR sensors, medical applications, and pyrometry; but also in IR imaging systems, and thermographic cameras. Typically operating in the 2µm to 14µm spectral range; that covers the LWIR (8-12μm) and MWIR (3-5μm) thermal imaging wavelength range. Our Germanium windows are available from stock, custom size and shape with Anti-Reflection coatings on one or both sides, and/or with Hard Carbon Diamond coatings. Read our PDF for more details...

Knight Optical are very experienced within the Thermal Imaging market, including anti-reflective and diamond-like-carbon coatings used on the optical components in these systems. Knight Optical know exactly what you are looking for. Thermal imaging uses infrared materials such as Germanium and Silicon, however in there raw form the transmission is not the best it could be. For example, Germanium typically transmits at <45% but with an AR coating applied, it can improve transmission to >60%. This increase in transmission means that the camera sensor receives a better signal through the protective window. Also with protective windows, we can provide high quality DLC coatings. We ensure the coating is Salt Fog Tested to MIL-SPEC standard to ensure that the coating withstands harsh environments. The coating has high mechanical hardness and high resilience to external stress. Read PDF for more information

The uniform, high-quality appearance of this triangular stand is ensured by the silver anodised click frames and the silver anodised aluminium round tubes. The simple assembly is done by screwing the 3 click frames to the 3 stable ø 60 mm aluminium legs. In order to effectively protect the inserted posters from rainwater, a circumferential sealing rubber is mounted on the weather-resistant metal rear walls, in addition the cover foil is glued to the rear wall on a short side. The cover foils used are made of non-reflecting, UV-stabilised material to prevent the posters from fading. Furthermore, the anti-reflection coating of the films ensures that the inserts are much easier to read even in sunlight. The posters can be changed quickly by opening the click frame profiles at the front. The highlight of this display is that the complete rear wall with foil can be removed for even easier poster changing.

Our nowadays lifestyle and its rather fast pace presents a sort of challenge to our eyesight. We expose our eyes to a number of negative factors. The most dangerous to eyesight are UV radiation and excess blue light emitted by screens of electronic devices. We have developed an effective way to transform these types of harmful wavelenghts of light into harmonized and beneficial radiation. This is possible thanks to special lenses in our eyewear that use the extraordinary properties of Fullerene C60 molecules. These lightweight eyeglasses resistant to fogging and scratching, are also covered with an anti-reflective coating. Hyperlight Eyewear computer glasses will allow you to safely take full advantage of the beneficial properties of the light reaching your eyes. When outside you will gain protection against harmful UV light, and while working - greater comfort, increased focus, memory and efficiency.
