IL300-EF

Manufacturer: Vishay

Description:
The IL300-EF consists of an AlGaAs infrared emitter irradiating an output PIN photodiode and a feedback photodiode. The feedback photodiode captures a percentage of the emitter’s flux and generates a control signal (IP1) that can be used to keep the emitter output constant by adjusting the emitter forward current. This compensates for the emitter’s non-linear, time, and temperature characteristics. The output PIN photodiode pro uces an output signal (IP2) that is linearly related to the servo optical flux created by the emitter. The time and temperature stability of the input-output coupler gain (K3) is insured by using matched PIN photodiodes that accurately track the output flux of the emitter.
