Angular Beam Shaper

Holo/Or has vast variety of solutions for beam shaping:
The 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 beam shaper enables equal treatment to a surface, preventing over or 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.
In this section, we present our beam shaper DOEs which give a flat uniform intensity distribution at infinity or focal length of an aberration free customer's lens.

For Multimode laser, we generally recommend to use our Beam homogenizer product line: Click here for more information on Beam Homogenizer.

DOE tuner - Holo/Or DOE Tuner A DOE Tuner is intended to fine-tune many characteristics of Beam-Shaping and Beam-Splitting results, as: adjusting separation angle of a MultiSpot DOE, Top-Hat size at the focal plane, or divergence angle of diffuser / Homogenizer. The DOE tuner can also be used as a small beam expander for fine-tuning the input beam size before the DOE (mainly for Top-Hats).
Beam Shaping Focuser - Holo/Or Beam Shaping Focuser The Beam Shaping Focuser is a focusing module optimized for Top-Hat (Beam Shaper) DOE. The focusing module is useful for short wavelengths and short Effective Focal Length (EFL) systems with large input beam size.
undesired orders blocker - Holo/Or Undesired Diffracted Orders Blocker (UDOB) An Undesired Diffracted Orders Blocker (UDOB) blocks undesired spots of MultiSpot or parasitic energy of diffuser / Homogenizer, enabling precise shape and energy distribution at the focal plane. The UDOB can be also used for making very sharp edges for diffuser / Homogenizer.
Dielectric mask - Holo/Or Dielectric Mask A Dielectric mask is a custom aperture built from a very thin high reflection/patterned layer (~1[┬Ám]), to improve performances when combined with a DOE, and minimize diffraction effects when used with an imaging lens.
DOE expander - Holo/Or DOE Expander The module reduces or expands the full angle of a DOE by a magnification factor. The module can be used as angle reducer or angle expander with our beam shaping, beam splitting and beam foci elements.
mounting adapters - Holo/Or Mounting Adapter Holo/Or supplies mounting adapters for use of smaller diameter optics (11, 12.5, 15, 18, 19, 20 and 22[mm]) to 25.4[mm] mounts, as well as adapters for use of square optics (7.25x7.25, 10x10, 12x12, 12.7x12.7, 14.1x14.1, 15x15[mm]) to 25.4[mm] mounts and 5x5[mm] to 11[mm] mounts.
