  • detection - Designing a wide-range light detector

    Infrared light is composed of light radiation with wavelengths in the 700 nm to 1000 nm range, a little longer than visible red light, and therefore infrared light cannot be seen by the naked eye. The phototransistor operates as a bipolar transistor with light as the effective input to its base.
