High accuracy compact beam positioning system. All electronics are built-in within the sensor head. Connects directly to PC via USB 2.0 interface.
Advantages A simple, fast and cost effective device to control laser beams in real time. Transforms your personal computer into a powerful measurement instrument. The standard program user interface includes a numerical and graphical presentation of position and power, long term fluctuation (Strip Chart type).Several different PSDs are available for sensing the position of beam’s centroid incident on the detector’s surface.

(*)To maintain full calibration accuracy, attenuating optical filters may be necessary for operation with beams greater than 1 mW. Saturating "non-linear" effects depend on the beam size, type and wavelength, but caution should be exercised when using the 4Quad PSD above 3-6mW or the Lateral Effect PSD above 1-3mW.
