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

Knight Optical can offer custom Rod Lenses for use within Optical Systems.
We supply a range of custom & stock Rod 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 with Optical systems. Rod Lenses are a special variant of cylindrical lenses so they focus light to a line. Rod lenses have an outside face that is polished and the ends are ground. Typical uses for rod lenses would be to generate a line image from a circular laser beam.
Rod lenses can be cut at 45 degrees for use in beam steering and other similar applications.
