Neutral Density + Beam Splitter Combo

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.

  • LBS-300s Attenuator

    LBS-300 Attenuator
    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 front

  • LBS-300HP-NIR Attenuator

    LBS-300HP-NIR Attenuator
    The LBS-300HP-NIR is a patent pending technology beam splitter for High Power lasers that allows measuring NIR (~1064nm) focused or collimated laser beam profiles up to 5kW or 15MW/cm². The LBS-300HP-NIR operates by reflecting a fraction of the incoming beam through the front surface of each of a pair of orthogonally oriented wedges. Less than 0.0001% (1/10 ⁶) of the beam is reflected towards the Ophir Beam Profiler Camera. This enables beam shape, focal spot, beam waist, M² of a

  • LBS-400 Attenuator

    LBS-400 Attenuator
    The LBS-400 beam sampler attachment for Pyrocam cameras allow you to measure UV or IR wavelength laser beams with diameters up to 1 inch (25.4mm) and powers ranging from 10mW to ~500W(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.
