BWA-CAM
BWA-CAM®
The BWA-CAM is a precision measurement system for analyzing focused laser beam profiles along the propagation axis. Using a high-resolution camera and automated translation stage, it captures and reconstructs the beam waist, divergence, and M² value with high accuracy. Compatible with a wide range of wavelengths and power levels, the BWA-CAM is ideal for laser alignment, process optimization, and research applications.

The BWA-CAM® (Beam Waist Analyzer CAMera) is the base module of the Beam Waist Analyzer system. The patented design contains “no moving components” and provides instantaneous 2-D and 3-D measurements, analysis and monitoring through more than one Rayleigh range of the laser beam and all active optical elements.

The BWA-CAM system supports a range of configuration options to handle different attenuation levels, beam sizes, and power levels. These components are offered separately from the base unit and are built to align with the specific requirements of each application. Because these configurations are not off-the-shelf, they are developed to suit the specifications of your laser setup. The BWA-CAM can be used on its own or combined with the appropriate modules for expanded capability.
