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 Read PDF for more information Material::Colour glass Length/width::± 0.20 mm Thickness::± 0.20 mm Surface quality::<60-40 scratch/dig Parallelism::<3 arcmin

KO can offer Metallic Neutral Density Filters for use in Photographic Applications. We supply a range of Metallic Neutral Density (ND) Filters for a variety of applications – all individually QA checked and metrology tested for quality to ensure parts meet customers’ specifications. What’s more, our Metallic ND Filters are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Our Metallic ND Filters reflect (with a metallic coating) light neutrally over a wavelength range (typically visual). They can be used to lower the intensity of light prior to the image plane. These are often used in photography, allowing photographers more flexibility with their setups to achieve desired effects. Often, an ND filter will be used in conjunction with a long exposure to prevent washed-out and overexposed images. They can also be used to add motion blur, reduce depth of field and to use a wider aperture.

ball lenses are spherical lenses mostly made out of High Refractive Index Glass - Knight Optical offer a range of Stock Ball Lenses and Half Ball Lenses, for use within Fibre Optics, Signal Coupling and Barcode Scanners. As the name suggests ball lenses are spherical lenses mostly made out of High Refractive Index Glass such as Sapphire, and LASFN-9 Glass. The reason ball lenses are most commonly used is for their ability to couple light in and out of fibres. The key feature of ball lenses is their short back focal length allowing for precision coupling where size or space is a limiting factor in the system. Ball lenses are typically used in pairs with one lens acting as a collimator for the second to focus the light back into the coupled fibre. Where a more compact solution is required a half-ball lens is typically more suitable. We hold a large inventory of Ball Lenses. •Stock sizes from 0.5 5mm to 10mm diameter. •Custom sizes available to quotation. •Half Ball lenses also available. For more information read PDF….

Looking to improve you medical system? Then look no further. Knight Optical presents to you their Dichroic colour filters range. These Dichroic colour filters are typically used in scientific instrumentation or/and medical systems in particular palm vein scanners, ophthalmic diagnostics, professional eye care equipment from optical equipment or ophthalmic instruments. Our Dichroic filters: • Have a hard dielectric coating and are designed to offer high transmission over a specific wavelength while reflecting all other wavelengths. •Offer superior contrast between transmitted and reflected wavelengths. Having a dielectric coating they are perfect for high power applications and do not show the strong fluorescence of certain glass filters. •Are temperature resistant and can be used to reflect heat away from hot lighting systems in addition to their colour correcting properties, unlike traditional polyester type colour filters that melt and distort under thermal conditions.

Una máquina termoselladora (o selladora de bolsas) es un dispositivo que se utiliza para sellar varios tipos de envases y materiales termoplásticos. Existen diferentes diseños para diferentes requisitos de trabajo de sellado. Al elegir un sellador térmico, la primera y más obvia pregunta es: ¿qué está tratando de sellar? Los selladores térmicos se utilizan para sellar una amplia variedad de materiales para adaptarse a muchas aplicaciones y proyectos diferentes. Las bolsas de sellado térmico están herméticamente selladas, lo que garantiza que sus productos sean a prueba de manipulaciones, herméticos, impermeables e higiénicamente cerrados. A menudo, tendrá una bolsa o bolsa precortada que contendrá monocapas idénticas. En otras palabras, solo materiales de "una sola capa". Como simples bolsas de plástico. Otros envases, como las bolsas de papel de aluminio o las bolsas de fuelle, pueden tener varias capas que deben sellarse a la vez.

Knight Optical can offer UV Fused Silica Lenses for Solid State Laser applications. UV FS is a prime choice for lenses in use with Solid State Lasers due to its consistently high transmission in the UV/VIS/NIR regions. This means that it can be used with a range of different laser types, such as Titanium-doped sapphire (tuneable to 660-1080nm) or Alexandrite (tuneable to 700-820nm) with very little change in performance. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher.

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….

Knight Optical can offer UV Fused Silica Lenses for Flame Detection Applications. UV Fused Silica can be used in Flame Detection Applications, due to its high transmission into the NIR range (approximately <92% avg 400-2000nm) meaning that a clear distinction can be made between different wavelengths of light. UV FS also has a very low coefficient of thermal expansion 0.55x10-6K-1 at 300K) compared to N-BK7 (7.1x10-6K-1), meaning that it can still provide optical performance under high temperature. UV FS also has a high melting point compared to N-BK7, providing further protection for your application in high temperature environments. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher.
