Product Introduction

A Top-Hat beam shaper converts a Gaussian input laser beam into a uniform intensity beam of any shape and size requested by the customer.

The beam shaping element is a diffractive optical element (DOE) used to transform a near-gaussian incident laser beam into a uniform-intensity spot of either round, rectangular, square, line or other shape with sharp edges in a specific work plane.

A uniform spot enables equal treatment to a surface, excluding over/under-exposure of specific areas. In addition, the spot is characterized by a sharp transition region that creates a clear border between the treated and untreated area.

The beam shaping can be a:

Focal Beam Shaping: Hybrid element (lens) or module which give a Top-Hat intensity distribution at a specific working distance (BFL of the lens or distance from exit location of the module to Top-Hat plane).

Angular Beam Shaping: Optical element (window) which gives a Top-Hat intensity distribution at infinity or focal length of aberration free customer's lens.

M-Shaper: Optical element (window) which gives a uniform exposure over scanned lines.

Small Angle Top Hat standard

Small Beam Shaper for scanning application (~1.5X Diffraction Limit)

Laser beams with Top-hat energy distribution are being used for different applications in the laser material processing industry. Most systems in this industry include scanners and F-θ lenses in order to direct and focus the beam on the substrate. HoloOr is proud to introduce a new design for ~1.5x(Diffraction limit) beam shapers DOEs (Diffractive Optical Element) which is considerably cheaper than regular Top-hats. Those DOEs are specially designed to operate with scanners/F-θ lenses under high power lasers. Placing the beam shaper DOE before the scanner will create a top-hat energy distribution at the F-θ lens working plane. The use of this beam shaper does not affect the focal length of the system.
