Ophir Photonics, global leader in precision laser measurement equipment and a Newport Corporation brand, has released 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 5š angle into a beam dump or power meter. A set of adjustable filters further reduce the intensity of the beam before reaching the camera.
