Introduction to Quad Laser Position Sensing Detectors And Monitor

The Gentec-EO QUAD-4Track takes advantage of the superior performance of their Pyroelectric Quadrant Detectors over Silicon quad and lateral effect photodiodes. These QUAD-E detectors are designed to measure pulsed lasers and QUAD-P detectors for CW or Quasi-CW lasers. The QUAD- 4Track Laser Position Monitor is a powerful, 4-channel, microprocessor-based instrument that not only measures beam position, but also the power or energy of the laser. This application note provides a basic overview of these products and their capabilities.
