The “Top-Hat” or “Flat-Top” beam shapers are diffractive optical elements (DOEs) used to transform a near-gaussian incident laser beam into a uniform-intensity (flat) spot of either round, rectangular, square, line or other shape with sharp edges in a specific work plane.

A uniform spot achieved by the top-hat beam shaper enables equal treatment to a surface, preventing over or under-exposure of specific areas. The beam shaper creates a well defined spot, with a flat-top profile, characterized by a sharp transition region that creates a clear border between treated and untreated areas.

Below is a list of our top-hat beam shaper DOEs, which gives flat uniform intensity distribution at infinity or focal length of an aberration free customer’s lens.

Typical applications for top-hat (flat-top) beam shapers include: Laser Ablation, Laser Welding, Laser perforation, Laser Scribing, Medical and aesthetic laser applications.
