Optical coating - Import export

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.

Coating substrates is one of our core competences. We have been coating precision optic components with optically effective layers ever since 1948. Over the years, technical specifications and possibilities have radically changed. We now have several highvacuum plants, an ultrasound cleaning and drying plant at our disposal to treat the substrates. We also build our own equipment e.g. for asymmetrical prisms. Coated substrates are inspected and documented with a "Lambda 900" PE spectral photometer. Antireflection coatings

Antireflective is an optical coating that reduces reflection and increases light transmission. As a result, it provides better transparency and view through glass. It is typically recommended when there is a great difference in brightness on one or both sides of the glass (such as displays, windows, facades...) Combination If you add our antireflective to our antiglare treatment, you will improve the optical performance towards zero reflection (except sodalime).

Knight Optical provide a wide range of optical components present in a spectrometers, specifically mirrors and prisms with a UV Aluminium coating to enable the detection of UV wavelengths from 180nm. UV wavelengths can be hard to detect without the use of this coating and can make results inaccurate. Knight Optical UV Aluminium coating allows wavelengths between 180-650nm to reflection at an average of of 85% which is not achieved with Enhanced Aluminium which cuts on at 400nm and primarily for the visible region and above. The coating can be applied to Prisms and Mirrors, either from stock or custom. It is also worth noting that the coating has a protective layer which improves resistance to scratching and improves durability making it easier to clean. Read PDF for more details

Colorimeters measure colour in a substance, for example in water. It defines the measurement of the colour to enable its identification, using the lightwave spectrum. Colorimeters are a form of a spectrophotometer. The use of mirrors in the system, redirect the light beam from the light source to the sample and back to the sensor to enable a reading. Knight Optical provide high quality coated front surface mirrors of varying reflection averages from stock and to custom specifications. Knight Optical provide several metallic coatings such as: •UV Enhanced Aluminium •Enhanced Aluminium •Protected Silver •Protected Gold •Visible Dielectric •NIR Dielectric These are all available as custom coatings depending on your requirements for your colorimeter.

Knight Optical can offer Pellin-Broca Prisms for use within Atomic Spectroscopy. We supply a range of Pellin-Broca Prisms 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 Atomic Spectroscopy. Pellin-Broca Prisms are designed with a given material, angle and wavelength in mind to perfectly deviate a beam of the given wavelength by 90 degrees. These are often used to separate beams of differing colours and as such are ideal for use in optical atomic spectroscopy or to separate outputs of a multi-line laser. For more information read PDF…

Hydrophobic means to repel water. Applying a hydrophobic coating to a surface can help the surface repel dirt and residue for easier cleaning. These types of coatings also have an oleophobic property, meaning that oil and grease is also repelled. Knight Optical provide Hydrophobic Coatings to wide range of protective windows made from materials such as BK7 or equivalent, UV Fused Silica or Borosilicate. Benefits for hydrophobic are that is: Optically Clear Easy-to-Clean Fingerprint and Smudge resistant The properties of the optical component itself remain unaltered meaning it does to hinder its current application or require a redesign. This coating would be a custom item and can be applied to most of our stock optical components. If you would like to discuss how a hydrophobic coating can enhance your application contact our technical sales team whom can assist. Read PDF for full specification

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
