Overview

The LBS-300s beam splitter attachment for C-mount, CS-mount, or Ophir mount cameras allows 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 canceled out and the resulting beam image is polarization corrected to restore the polarization components of the original beam.

⁽¹⁾For Gaussian beam diameter <1/2 the clear aperture and depending on ND filter and camera saturation limits the maximum power may be as high as 1000W.

C-mount, CS-mount, or Ophir mount
Diameters up to 15 mm
Powers from 10 mW to ~400 W(1)

LBS-300 Beam Sampler Overview

The LBS-300 beam sampler allows you to safely measure laser beams with diameters up to 15mm and powers ranging from 10mW to ~400W using a CCD camera. This video describes the LBS-300 features.

Frequently Asked Questions

Can I use LBS both for beam profiling and power measurement?
Answer
Yes, the main function of LBS-300s beam splitter is Beam profiling, however, it performs a 3-way beam splitting: less than 0.01% (1/103) of the beam is reflected in one direction, about 1% in another direction, while the remaining 99% of the incident laser beam is transmitted.
This allows users to measure one of the 3 beams, depending on available power measurement equipment and setup convenience.

Which equipment can be connected to LBS-300s threads?
Answer
LBS-300s is equipped with 2 C-Mount threads and 2 CS-Mount threads.
An input C-Mount thread is designated to connect optional Wedge Splitter (SP90273) to reduce power density or beam extending negative Lenses (SP90187/88/90) to locate the focal spot in required position.
An output C-Mounts thread is mostly used to connect Ophir's Beam profiling camera. Extension tube between LBS-300s and camera can also be used to reduce noise on the camera and power density on LBS-300s adjustable ND filters.
A 1^stand 2^nd beam out, equipped with CS-Mount 1.035-40, enables connecting Ophir Power meters such as PD300R family (7Z02436/7/8/9) or one of the beam deflectors.

How to deal with removable Beam Blocker?
Answer
The beam blocker is designated to keep one wedge surface protected during handling and shipping. It can be left attached for low power laser operations. However, in the case of high-power laser irradiation scattered light might interfere with beam profile measurement and cause offset. In case of such offset, we recommend removing the beam blocker.
After removal, an additional laser output, having less than 0.1% of incident beam power will be reflected. That beam could be used for simultaneous measurement of laser power via Ophir Power Meter in addition to beam profiler.

What should be my Safety concerns while using LBS-300?
Answer
Regular laser safety precautions should apply. Please note, that the main incident beam will exit the LBS-300 refracted approximately 6°. Provision must be made to safely contain the transmitted beam by beam dump or power meter.
