Lasers & Opto-Electronics
Holmarc’s Photoconductivity Experiment Apparatus is designed for the experimental study of the photoconductive properties of photo resistors. The setup enables students and researchers to investigate the variation in electrical conductivity of a photo resistor when illuminated with light of different intensities. The apparatus provides a simple and reliable platform for understanding the fundamental principles of photoconductivity and the operation of light-sensitive semiconductor devices.
The experiment consists of a laser source, photoconductive sample with holder, regulated power supply, polarizer rotator, precision current measurement unit, and associated opto-mechanical components mounted on a rigid optical platform. The modular construction allows easy alignment and replacement of individual components while giving users hands-on experience in setting up the experiment.
Light intensity incident on the photoconductive sample can be varied using a polariser rotator, enabling accurate measurement of photocurrent and dark current characteristics. The experimental setup is suitable for undergraduate and postgraduate laboratory courses in solid state physics, semiconductor physics, opto-electronics, and material science.
Experiment Possible
Study of photoconductivity in semiconductor materials.
Measurement of dark current and photocurrent.
