Edmund Optics (EO) has released new flat top beam shapers. These refractive field mapping optical systems convert a Gaussian beam profile to a flat top profile with near 100 per cent efficiency.
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. The devices have no internal focusing, so they are suitable for applications that require high power lasers, including material micromachining, welding, and engraving.
The beam shapers are available with design wavelengths from 266 to 10,500nm, for common YAG, fibre laser and CO2 laser sources. Each device 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.
