LBS-300-HP-NIR Overview

The LBS-300HP-NIR beam splitter allows camera-based beam profiling for high power lasers.

Uniform Attenuation of Any Beam Shape

Each optical path through the LBS-300HP-NIR provides uniform attenuation of any beam shape (Gaussian, flat-top, doughnut, etc.) while preserving the polarization and overall profile of the incoming laser beam thus providing accurate sample of incident beam. A 1.035-40 thread is provided behind each wedge along the axis of the output beam. These can be used to directly mount accessories with 1” lens tubes such as beam dumps or power/energy sensors.
