Basic principles of piShaper 4.5 4.5 operation:

piShaper transforms Gaussian intensity distribution of source laser beam to a flattop one;
TEMoo or multimode with Gaussian or similar intensity profile can be applied;
Achromatic design provdes this transformation for a certain wavelength range;
Galilean design, thus there are no intermediate focusing of a beam;
There are two versions of the piShaper 4.5_4.5 systems available: Telescope and Collimator;
With changing the size of input beam the output beam profile changes as well;
When changing the shape of input beam it is possible to adapt the piShaper to provide flattop output profile, this adaptation is realized through changing the diameter of source beam;
Versions of the piShaper 4.5_4.5 for other wavelengths ranges are, also, available.
