NIR POSITION SENSORS - 2-COLOR DETECTORS - QUADRANTS
NIR Position Sensors

The G-series Germanium and IGA-series InGaAs Position Sensors are a family of lateral effect photodiodes sensitive in the near-IR region of the spectrum - from 800nm to 1700nm. They offer continuous position sensing capability over a selection of active sizes and are available as components or as integrated photodiode/preamplifier subassemblies.

2-Color Detectors

EOS manufactures two-color detector components, each with a different spectral response, mounted in a sandwich style configuration. This geometry has its top photodetector with normal operating characteristics. However, it also acts as a long wavepass spectral filter over the bottom detector.

Quadrant Detectors
Silicon and InGaAs

To expand the line of position sensing devices, EOS has added several quadrant detectors to our standard product line. These are high performance devices and come in room temperature or TE-Cooled TO-Style packages. 4-channel integrated amplifier modules are also available. Other sizes and configurations are available on request.
