Newport CONEX-PSD10 GE Germanium Optical Beam Position Detector Laser XY Stabilization Sensor w/ Control Computer.
Used see photos. In excellent condition, it was hardly used in its former lab. The dust cover has been always attached when not in-use.
Tested works and interacts with the tests performed by our technician (see video): youtube.com/watch?v=_KCgGprkcBU

From the manufacturer:
"The CONEX-PSD10GE Position Sensing Detector provides accurate XY position information of laser beams and is ideally suited for laser beam stabilization, laser tracking and general beam diagnostics. Unlike quadrant detectors, the improved tetra-lateral effect diode of the CONEX-PSD10GE is highly linear over the full sensor size of 10 mm x 10 mm, and delivers a third signal proportional to the beam power.
Different than many detectors that are tweaked for high bandwidth, the CONEX-PSD10GE has been optimized for stability and compatibility with pulsed laser beams. An analog input filter with 136 Hz cut-off frequency suppresses high frequency noise and undesired signal ringing when used with pulsed lasers. An additional digital low pass filter can be set by software in a frequency range from 0 Hz to 1000 Hz to further improve signal homogeneity."
