When imaging larger laser beams, fitting the beam on the imager becomes an issue. Array size of the Spiricon camera or the detector size of the NanoScan head being used is the limiting factor of how large the beam can be to properly analyze. Beam Expanders are the best way to decrease the size of the beam for the best measurement and analysis.
The 4X Beam Reducer is an imaging system that images the plane 30cm in front of the reducer onto the camera CCD sensor while reducing the size 4 times and inverting it. The beam reducer uses the 3 screw on attenuators provided with the camera. Since the intensity of a beam after reduction will be increased by 4x4=16 times.Show Product >
