Position Sensing ModulesPosition Sensing Modules are fully packaged silicon position sensing photodiodes that provide an analog output directly proportional to the position of a light spot on the detector active area. Each module contains either a quadrant, duolateral or linear position sensing detector conveniently packaged to allow simultaneous monitoring of position and light intensity. A DB9 subminiture 9-pin connector allows direct connection into all On-Trak Photonics Position Sensing Amplifiers. For operation in harsh ambient lighting conditions, each module can accept an optical filter. A blank, removable filter holder assembly is provided with each module at no extra expense. Filters for common laser wavelengths are available as optional accessories depending on the application.
