Beam Analyzer System
Description
The measuring technique is based on a multiple scanning knife-edge technology, combined with a tomographic image
reconstruction for the creation of the 2D/3D display. When the drum spins, the knife-edges cut across the beam in an
orthogonal plane to the direction of propagation. A stationary large detector inside the spinning drum measures light
intensity. For attenuation, when needed, a built-in distortion free optical filter is inserted between the spinning drum
and the detector. This technique provides the required attenuation without affecting beam quality. Each scanning
knife-edge is oriented at a different angle on the drum and moves across the beam path in a different direction as the
drum rotates. Consequently, during a single rotation of the drum, the instrument generates a set of profile curves, each
representing the intensity profile of the beam from a different direction. This data is the input for the tomographic
reconstruction algorithm to generate the 2D/3D intensity profile
of the beam.

The BA7 uses seven individual knife-edges, providing more accurate
measurement of the true beam shape and dimensions by gathering
data from all 7 scans, while the BA3 uses only three knife-edges, and
is recommended for smaller beams measurement as well as for a
near-Gaussian beams. The more knife-edges, the greater the level of
detail obtained. For a beam distribution that is significantly
non-Gaussian the BA7 would reconstruct a plot that closely matches
the real beam.

The Beam Analyzer is offered in two types of measuring heads: The BA7 uses seven individual knife-edges, providing more accurate measurement of the true beam shape and dimensions by gathering data from all 7 scans, while the BA3 uses only three knife-edges, and is recommended for smaller beams measurement as well as for a near-Gaussian beams.
The Beam Analyzer System has a wide spectral range, from 190nm through 1800nm.
The main applications of the Beam Analyzer System include laser beam profile measurements, QC of lasers, and monitoring multiple beams' centroids.
