Introduction
Optical sensors made with photodiodes are used extensively in many industries for a wide variety of applications. BPW 34 BS-Z is an example of such sensors. It is a silicon-based photodiode that combines both light intensity and wavelength sensitivity in one package. It is widely used in industrial, telecom and automotive industries for various applications. This article will look at how BPW 34 BS-Z optical sensors work, their application fields and the working principles behind them.Technology
BPW 34 BS-Z optical sensors are based on a silicon-based photodiode. The photodiode is a device that converts light energy into an electrical signal. The device is fabricated using a semiconductor material such as silicon and has an active layer where the photocarriers (electron-hole pairs) are generated when light is incident on it. The photodiode responds to light energy in the form of either a current or voltage depending upon its type and connection.Working Principle
When light strikes the BPW 34 BS-Z optical sensor, the quanta of energy from the incident photons produces electron-hole pairs in the active junction of the photodiode. As electric field is applied across the electrodes, the electrons and holes are collected from the semiconductor junction resulting in a current flow through the circuit proportional to the number of electron-hole pairs collected and hence to the intensity of the incident light. The voltage that is produced is directly proportional to the incident light intensity.Application Field of BPW 34 BS-Z Optical Sensor
