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

Knight Optical offer a range of Stock Achromatic Doublet Lenses for use within Light Engines. Light engines are used for applications such as fibre optic lighting displays & in diagnostic tools like western blots & polymerase chain reaction systems. These Light Engines are typically able to produce changing colour displays. Within the light engine are a range of lenses & filters. The lenses help to homogenise and collimate the light, ensuring for a crisp high-quality beam output. Achromatic Doublets are typically used in light engine systems & correct for chromatic aberrations which exist in singlet lenses. This is when different wavelengths of light refract at different rates. The doublet lens helps to correct this by facilitating the focusing of the light to the same point. This is especially important in light engines which typically generate white light. Read PDF for more information

Knight Optical can offer you Stock and Custom Colour Glass Filters, for use within Inline Cameras in a range of materials of brands such as Schott, Kopp and CDGM. Depending on the achievable wavelength and desired affect you need for the Inline Camera we can find a suitable material for your application. Colour Glass Filters are good for selecting a particular wavelength to be absorbed so that the high out of band blocking in achieved. With regards to the use in Inline Cameras, Colour Glass Short pass Filters are more desirable as they cut out the IR wavelengths mean the imaging is not saturated with the IR giving the image better clarity. Colour Glass Filters are polished sheets of special glass that have been cast with a dye. Colour Glass Filters generally are relatively cheap and very stable. The disadvantage with them is that they are only available in a relatively small number of variants, and so can be restrictive in shortwave selection. For More Info see PDF...

Knight Optical can offer you Custom Sapphire Cylindrical Lenses, for use within Endoscopes. We supply a range of Sapphire options for a variety of applications – all individually QA checked and metrology tested for quality to ensure parts meet customers’ specifications. What’re more, our Sapphire Cylindrical Lenses are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. 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 camera systems. Cylindrical lenses are designed to focus light into a straight line, rather than to a single point. As the name suggests, the lens surface has a cylindrical shape rather than the usual spherical formation, which allows for one-dimensional shaping of light along a line. Cylindrical lenses are often used to change the profile of laser beams; for example Read PDF for more info
