Introduction to Detectors for Photo-Research Systems

Introduction to Detectors for Photo-Research Systems

A detector in a typical photo-research system quantifies the radiant intensity applied for inducing photo-response in a sample or the radiant intensity generated by the sample when it responds to light or other simulation. [More]
Using Multi-channel Detectors for Plasma Monitoring Applications

Using Multi-channel Detectors for Plasma Monitoring Applications

A typical application for multichannel detectors is plasma diagnostics, which involves analysis of contaminant presence and relative concentration. The spectrum of the base gas of the plasma is examined to determine the presence of spectral lines that are uncharacteristic to the gas. [More]
