  • Photodiode/Phototransistor Application Circuit

    Photodiode sensors have a high degree of linearity over a large range of light power levels: from fractions of a nanowatt to about 2 mW. Above that light level, corresponding to a current of about 1 mA, the sensor saturates and reads erroneously low. Therefore, most Ophir PD sensors have a built-in and removable attenuator allows measurement of up to 3 W without saturation.

    The root of the theory behind this phenomenon is a small energy gap between the valence and conduction bands of the detector. When light, with enough energy to excite an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current in an external circuit.
