High power lasers >300W up to thousands of watts Scanning slit profilers can measure beams directly without attenuation. Of course, as we’ve seen, CCD and CMOS cameras will always need attenuation. It will also determine the detector type. The amount of power being measured will affect whether or not attenuation or beam splitting is needed. Pyroelectric detector equipped scanning slit profiler The pixels on silicon arrays are down to ~4 m m Silicon cameras, with smaller pixel sizes Silicon and InGaAsarray pixels and scanning slit systems Scanning slit systems are available with apertures up to 25mm.īeam should cover about 10×10 pixels. Silicon, InGaAs, Phosphor coated and Pyroelectric arrays are suitable. Pyroelectricimagers and scanning slit systems, can operate into the far infrared. They include CCD or CMOS cameras and silicon detector-equipped scanning aperture systems. These are the most cost-effective profilers. Silicon detector camera and scanning slit based profilers. Here is a table with examples of some of the ways these factors affect the laser profilers needed:
