Press Release Summary:

August 22, 2014 - Featuring set of adjustable filters for intensity reduction, LBS-400 laser beam samplers are dual-wedge attenuators that control and adjust beam output power that reaches Pyrocam™ pyroelectric beam profiling camera. Compact and portable products measure UV, NIR, or IR wavelength beams with diameters up to 1 in. and power levels from 10 mW to 500 W. Mid-IR and Far-IR wavelength lasers with focused spots down to approximately 1.5 mm can be characterized as well.

Ophir-Spiricon Announces Laser Beam Splitters/Attenuators for Large Beams to 1-Inch Diameter, Powers to 500W

Ophir Photonics LBS-400 Beam Splitters

North Logan, UT — Ophir Photonics Group, the global leader in precision laser measurement equipment and a Newport Corporation brand, today announced the LBS-400 Beam Splitters, a family of laser beam samplers that control and adjust beam output power that reaches the beam profiling camera. The LBS-400 samplers are the largest, dual-wedge attenuators on the market. They measure UV, NIR, or IR wavelength beams with diameters up to 1 inch (25.4mm) and power levels from 10mW to 500W. For use with the Pyrocam™ pyroelectric beam profiling cameras, the splitters combine a compact, portable design with high power ranges, making the LBS-400 an ideal solution in any situation where beam profiling must be performed in a relatively small area. In addition, Mid-IR and Far-IR wavelength lasers with focused spots down to approximately 1.5mm can be easily characterized.

The LBS-400 Beam Splitters are designed so 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 splitters reflect approximately 1% of the input beam, allowing about 99% of the beam to pass through at a 5° angle into a beam dump or power meter. A set of adjustable filters further reduce the intensity of the beam before reaching the camera.

There are three LBS-400 configurations:
LBS-400-UV: fused silica UV wedges for wavelengths from 266 – 355nm, sampling ≤ 1.5% of the beam
LBS-300-NIR: BK7 wedges for 1064nm wavelengths, sampling ≤ 1% of the beam
LBS-300-IR: ZnSe wedges for 10.6µm, sampling ≤ 1% of the beam

Pricing and Availability
The LBS-400 Beam Splitters are available now. OEM pricing available on request.
