Custom Optical Bandpass Filters
Product Announcement from PIXELTEQ
Optical bandpass filters selectively transmit targeted spectral bands and block out-of-band wavelengths across the range - improving signal-to-noise ratio and improving contrast…customized for central wavelength, spectral bandwidth, blocking range, and blocking level.
NIR Bandpass filters are used whenever there is a need to increase the signal-to-noise ratio of photodetectors (silicon). They protect detectors from undesired ambient background radiation (e.g. sunlight) or in-house illumination sources such as halogen or mercury lamps. This reduction of unwanted energy enhances detection of the target's signal.
