BEAM SHAPER ST-291-I-Y-A
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.
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. Read more about Top-Hat Beam Shapers applications. For Multimode laser, we generally recommend to use our Beam homogenizer product line. Click here for more information on Beam Homogenizer.

Frequently Asked Questions
A top-hat beam shaper is a diffractive optical element used to transform a near-gaussian laser beam into a uniform-intensity spot with sharp edges in a specific work plane.
Typical applications of top-hat beam shapers include laser ablation, laser welding, laser perforation, laser scribing, and medical and aesthetic laser applications.
The ST-291-I-Y-A beam shaper has very good uniformity, high efficiency, a sharp beam edge, high power threshold, optional Ar/Ar coating, and can produce any output beam profile.
The input parameters for the ST-291-I-Y-A beam shaper include a wavelength of 1064 nm and a required beam diameter at 1/e2 of 2 mm.
The output shape of the ST-291-I-Y-A beam shaper is square, with a full angle at 1/e2 of 1.02 mRad and a transfer region of 0.25 mRad. The transmission efficiency is close to 100% and the overall efficiency is approximately 84%.
