The unit comes with USB2.0 interface, detector and software work with Windows XP/Vista/7/8/10.

(*) - 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 3-6 mW or the Lateral Effect PSD above 1-3 mW.
