NIR Triple Bandpass filter Glass Optical Filter Laser Lens for Machine Vision

Dual bandpass filter

A dual bandpass filter pass visible light and a specific portion of the visible (VIS) and near-infrared (NIR) spectrums. They are ideal for color camera applications that utilize daytime sunlight and NIR illumination at night. These filters achieve accurate color rendition by blocking interfering wavelengths and eliminate the need for dual sensor imaging.

About bandpass filter     

An optical bandpass filter has a transmission band surrounded by two blocking bands that allow only a portion of the spectrum to pass. These optical bandpass filters have broad spectral bandwidths in either the ultraviolet, visible, or infrared spectrums. The nearly black filters absorb visible radiation. They are perfect for ultraviolet or infrared detection applications. UV filters are often used to selectively transmit the 254nm and 365nm mercury lines. IR filters are often used in nightvision and IR sensing systems.
