Product name : Rectangular Shape
Description :
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.
For Multimode laser, we generally recommend to use our Beam homogenizer product line.
Applications:
● Laser materials processing: perforation, welding, cutting, scribing, ablation and drilling
● Biomedical applications
● Laser displays
● Marking and printing
