Reduction of the laser power before reaching the camera is often times required to obtain a usable signal, one that is not saturating or damaging the camera. These systems reduce the laser power by first sampling the beam, one or multiple times, and then absorbing the beam with optical density filters.
The LBS-300s beam splitter attachment for C-mount, CS-mount, or Ophir mount cameras allow you to measure laser beams with diameters up to 15mm and powers ranging from 10mW to ~400W(1). The beam sampler is designed so that the preferential polarization selection effect of a single wedge is cancelled out and the resulting beam image is polarization corrected to restore the polarization components of the original beam. The beam sampler operates by reflecting the incoming beam from the frontShow Product >
