Knight Optical offers these carefully designed NIR bandpass filters for use in ANPR/ALPR camera applications. Designed specifically to work at maximum efficiency transmitting over 90% at the commonly used LED wavelengths of 740nm, 850nm 870nm or 940nm.
Our filters have a “hard dielectric” coating deposited on a single glass substrate eliminating the need for traditional multi-element stacked bandpass filters which can be susceptible to leakage or moisture ingress.
These stock NIR, LED bandpass filters are coated onto 25mm dia x 2mm thk clear white plate glass or a coloured glass substrates and can be supplied unmounted or mounted into our stock range of anodized camera rings with 0.5mm pitch threads designed to fit directly onto Tamron, Fujinon or Sony lenses. Mount sizes available are either 25.5mm or 30.5mm sized options. The 25mm dia filter simple screw inside with a simple retaining ring and have 22mm dia clear aperture.
All of our filters are tested in house by our metrology team, and the coating is verified on our Agilent Cary 5000 spectrophotometers. Complete coating information is available on request.
ANPR filters can be custom manufactured to fit individual systems, or quickly resized in house to for fast turnarounds. For more information on our stock range of NIR bandpass filters for ANPR applications, or to enquire about a custom quotation, please contact our technical sales team.
