Melles Griot Spot-On CCD detectors systems can be used to provide accurate position measurement of up to three cw and pulsed beams, from the ultraviolet to the near infrared. The units will calculate beam centroids, display two-dimensional contour maps of beam energy in real time.

Export data to another computer through the RS 232 interface, log data, and keep detailed statistics. If greater beam profiling capability is needed, see the WinCamD CCD beam profiler.

The Spot-On CCD system is available with four different detector heads, each designed for a specific wavelength range.
