Focusing module

Standard focusing lenses are normally optimised for use with Gaussian beams and not with beam shapers. Using these lenses with beam shapers leads to aberrations on the Top Hat image, negating the shape of the Top Hat DOE. In order to solve this,Standard focusing lenses are normally optimised for use with Gaussian beams and not with beam shapers. Using these lenses with beam shapers leads to aberrations on the Top Hat image, negating the shape of the Top Hat DOE.

In order to solve this, Holo/Or has designed a focusing module adapted to work in concert with our beam shaper. The module contains an array of lenses, and a Top-Hat image is produced at the back focal length of the module. The module is compact and comes in several focal lengths depending on the system’s requirements.
