Description

     IR FILTER FEATURE     

Beyond light is infrared radiation, which takes up a large portion of the scale, with wavelengths from 700 nanometers to 1 millimeter. 

Our eyes are not sensitive to infrared radiation, at least not in ways we can visually interpret, but digital sensors are, which causes some problems. It can be very difficult for an electronic circuit to differentiate between the various forms of radiation as to what is good light and what is bad infrared. All digital cameras except those specially designed for “night vision” feature infrared cut filters to limit the amount of infrared radiation that strikes the sensor and can be misinterpreted as light.
