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 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

Unwanted hair, be gone! Knight Optical offer a range of Stock Dichroic Filters, for use within IPL Applications. Intense Pulsed Light filters are essential to IPL applicators as they are used to filter out the UV wavelength range; and transmit between 400-1200nm for use within cosmetic lasers that are designed to remove unwanted hair, vascular treatment and even acne treatment. These IPL Filters are often stacked between sapphire windows within the IPL applicator to offer a more defined wavelength spectrum when in use. Dichroic filters consist of thin film dielectric coatings on glass, and are designed to offer high transmission over a specific wavelength while reflecting all other wavelengths, having negligible absorption. The dielectric coating is perfect for high power applications, and does not show the strong fluorescence of certain glass filters. We hold a massive inventory of Bandpass, Long pass, Short pass, Band-blocking and Colour-correction filters. Diameter Tolerance::Borosilicate or equivalent, Sodalime Length/Width Tolerance: :+/- 0.25mm Wavelength Range::300nm-1200nm dependant on type Wavelength Accuracy: :+/- 5nm Thickness Tolerance: :+/-0.20mm Transmission: :Tmax=95% dependant on type and substrate

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

UVFS prisms for UV wavelength 170nm & other high index materials in VIS apps - 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 Materials::UV grade fused silica,F2, SF11 or equivalent Dimensions::± 0.2 mm Surface quality::<60-40 scratch/dig Coating::Antireflective Coating for visible (AV7)

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 Calcium Fluoride Lenses for use within the Oil and Gas Industry. We supply a range of calcium fluoride 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 in the oil and gas industry for use within detectors and spectrophotometers. For spectroscopy, calcium fluoride is superior to many other materials such as N-BK7 or fused quartz due to a lack of OH absorption peaks. Due to calcium fluoride’s low absorption and reflection and high damage threshold these lenses can often be used uncoated and are ideal for use in laser applications as well as thermal imaging systems, spectroscopy and high energy neutron detection.

Automatic Number Place Recognition Cameras otherwise known as ANPRs; are camera devices designed to work at certain wavelengths (dependent on Country) to read a license plate’s number of a vehicle to then track it through a database to identify any criminal offences links to that car, such as uninsured; stolen; major and organised crime; and even terrorism. They are typically installed on motorways; busy roads around cities and towns; and also on police cars as well as specialised ANPR police vans. Knight Optical offers Colour Glass Filters for such an application, be it either long pass or bandpass filters. The wavelengths typically used by ANPR camera companies are: 695nm; 740nm; 810nm; 850nm; 910nm and 940nm. We offer these filters as either long pass or band pass filters. We can also offer these as customised filters with specific band blocking coatings to optimise your wavelength of choice.

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…
