DOE Tuner

Holo/Or has designed a variable beam tuner for use with its diffractive optical elements (DOEs). Placing the DOE Tuner between the DOE and the focusing lens enables image size control in most elements, and in Multi Spot beam splitters, finer control over the separation angle. The DOE Tuner can also be placed before the DOE in order to fine-tune the input beam size. In beam splitter elements this placement can also control the output spot size. For Top Hat beam shapers, nominal beam size can be achieved. This is especially useful considering that the precision of the incident beam size is important with this type of element.
