Photon inc. Products - BeamScan Scan Head Chart - Dual Axis Scan heads for silicon, germanium, and pyroelectric detectors.

Scan Heads

Photon inc. manufactures scan heads for both CW and pulsed (q-switched) sources. BeamScan scan heads cover wavelengths from UV through far IR, beam sizes from a few microns to 25 mm in diameter, and power from microwatts to 100 watts. Photon will design and build semi-customized profiling system to work with nearly any application. The chart below gives information on standard available scan head models. The model number includes information on the head type, slit size and options. Please note that this is only a partial list; the specifications are not absolute and are a guide only. All available scan heads operate with CW sources and XYQSW heads operate with q-switched sources.
