Conventional charge-coupled device (CCD) and complementary metal oxide semiconductor (CMOS) sensors can exhibit near-infrared (IR) sensitivity from 700 nm to approximately 1,100 nm and can be converted to an inexpensive infrared (IR) imager with the use of a near-IR bandpass filter.
MidOpt® Near-IR range Filters provide excellent contrast in applications operating in the Near Infrared. These filters block visible spectrum (ambient) light, as well as long-wave infrared light. Only the selected wavelengths in the near infrared (NIR) range are transmitted to the sensor.
NEAR-IR FILTERS
Bandpass
NIR Bandpass Filters are great solution for working in specific NIR wavelength bands. This could be to match the transmission of NIR LED Light Sources while blocking visible and other ambient NIR wavelengths.

Longpass
Longpass filters are frequently used as Visible Cut filters with CMOS and CCD cameras. This filters out the visible light while allowing the camera to image in any NIR wavelength.
