| The LBS-300 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 10 mWatts to ~400 Watts1. 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 oncoming beam from the front surfaces of a pair of wedges through 90 degrees into the camera. Approximately
99% of the beam is transmitted through the beam sampler with .01% passed on to the camera. A set of adjustable ND filters are provided to make final
intensity adjustments to the beam before it reaches the camera imager. As an option, you may order the WVF-300 SP90195 continuously variable ND filter
set that can slide in and replace the fixed ND filters.If additional attenuation is needed, an external wedge (P/N SPZ17015) may be mounted at the input
port, however this 3rd wedge will cause polarization selectivity when the beam is significantly polarized different in the S and P planes. Alternatively, two
LBS-300s can be coupled in series providing up to a 10-8 attenuation. |
