Flat top beam shapers

Edmund Optics (EO), the premier provider of optical components, introduces new Flat Top Beam Shapers. These refractive field mapping optical systems convert a Gaussian beam profile to a flat top profile with near 100% efficiency.

No internal focusing enables use with high power lasers

Flat Top Beam Shapers convert collimated Gaussian input beams into collimated flat top beams with a uniform density distribution and a flat phase front. As a result of the field mapping optical design, the converted beam features an even intensity distribution, which is stable over great distances. This makes the converted beam ideally suited for holography, microscopy, and system integration. Flat Top Beam Shapers have no internal focusing, so they are an excellent solution in applications that require high power lasers, including material micromachining, welding, and engraving.

Variety of design wavelengths offered for common YAG, fiber laser, and CO2 sources

Flat Top Beam Shapers are available with design wavelengths from 266 nm to 10.500 nm, for common YAG, fiber laser and CO2 laser sources. Each Flat Top Beam Shaper operates over a specified wavelength range for laser tuning and the use of multiple laser sources. An optional 4-Axis Flat Top Beam Shaper Mount and a Flat Top Beam Shaper Aligner are also available for ease of alignment and integration into optical systems. Flat Top Beam Shapers are in-stock and available for immediate delivery.
