Beam diagnostics

The performance of today’s laser systems can strongly affect the success of demanding, modern laser applications. The beams’ size, shape, uniformity or approximation to the expected power distribution, as well as its divergence and mode content can make or break an application. Accurate knowledge of these parameters is essential to the success of any laser-based endeavor. As laser applications push the boundaries of laser performance it is becoming more critical to use beam diagnostics tools. For over thirty years Ophir-Spiricon has developed instruments to accurately measure critical laser parameters. Our LBA and BeamStar software have led the way. Now with the introduction of BeamGage, Ophir-Spiricon offers the first “new from the ground up” beam profile analysis instrument the industry has experienced in over 10 years.

Accessories for Beam Profiling

Spiricon has the most extensive array of accessories for beam profiling existing. There are components for attenuating, filtering, beam splitting, magnifying, reducing and wavelength conversion. There are components for wavelengths from the deep UV to CO2 wavelengths. Most of the components are modular so they can be mixed and matched with each other to solve almost any beam profiling requirement needed.
