Optical Filters for Traffi c Enforcement and ANPR
With more and more people taking to the road every year and the sweeping develop-
ment of a smarter motorway, the need for traffi c enforcement has come to the forefront
once again. Special cameras and laser systems with the ability to capture accurate speed
measurements, coupled with automatic number plate recognition (ANPR) are deployed in
growing numbers.
Such systems are used to monitor cars travelling over the speed limit or cars that have
exceeded the allocated parking restrictions. With the ANPR functionality, traffi c enforce-
ment companies no longer need to manually patrol and log the particulars of a vehicle at
a given location. Such systems streamline the entire process of traffi c enforcement, from
identifying the culprit vehicle, to automatically generating the letters which are linked with
the national car database to identify the owners of the vehicle. This ultimately saves the
enforcement company time and valuable resources in pursuing those who contravene.
LASER COMPONENTS can help support manufacturers of such traffi c enforcement systems
by providing a range of high precision optical bandpass fi lters. These range of fi lters are
centred at 740nm, 850nm, 870nm and 940nm. Typically these fi lters are provided as 25mm
dia, supplied with and without mounts. These fi lters are hard coated with >90% peak trans-
mission, ensuring accurate number plate capture. The hard coating gives good environ-
mental durability meaning they are ideal for outdoor applications
