LBS-300s Attenuator

Combination Neutral Density Filters and Dual Beam Sampling Optic System
Description: 

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 10 mWatts to ~400 Watts. 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 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 0.01%
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. If additional attenuation is needed, an external wedge 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. A 1.035-40 thread is provided behind
each wedge along the axis of the output beam that can be used to directly mount accessories with 1” lens tubes such as beam dumps or
even power and energy sensors to the LBS-300s.
