Collimated Beam shaper - Diffractive optics

Collimated Flat Top / beam shaper
Our Collimated beam shaping module is Holo/Or's tailored solution for applications requiring a wide working distance range or an extended depth of focus. The Collimated flat top is the natural complement for our more standard flat top beam shaper element which gives a uniform-intensity beam at a unique specified working distance. With a Collimated beam shaper module, the uniform-intensity beam is maintained with high fidelity, power uniformity, and constant size/shape over an extended working distance range. The shape is well-defined with sharp edges, and can be round, square, rectangular, elliptical, a thin line, a cross, or any other dimension suiting the user. The Collimated Top-Hat will be a good solution for applications such as industrial surface processing/cutting where the working surface can be located at widely varying distances from the laser delivery system. This ensures that the processing will be even and smooth with a clean edge at any working distance suiting the user's convenience, in the specified range.
