Duma Optronics is a company that sells laser instrumentation technology. The company was established in 1989, and develops and manufactures three product lines: Laser beam profiler, Laser beam positioning, Laser Beam alignment and Electronic autocollimators.
The CCD Profiler CCD beam profiler overcomes the limited dynamic range of camera type Laser beam Profilers and accurately measures faint laser beam structures by sampling the beam several times. Each measurement is performed at a different attenuation or electronic shutter speed. This patented technology enables the users to view features that are smaller than 1% of the laser beam's maximum power density. The proprietary shutter activation allows examination of the laser beam with in a fraction of percent from the peak intensity.
Secondly, the use of Knife Edge type analyzers, a unique state-of-the-art technology (patented), enabling a knife edge profiling the beam at various intersection angles, followed by a Tomographic reconstruction algorithm, generating the spatial intensity distribution map at the intersection plane.
Duma Optronics is the first company that used the tomographic beam analysis concept which enables a scanning knife system to reconstruct and display a full image of a laser beam. The tomographic technique is based on a rotating drum with multiple knife edges, scanning the beam at different orientations. This technique is of high interest especially for modern laser systems which require high laser power measurement (up to 3 kW).
