532nm Rectangular Flat-Top Beam Shaping Diffractive Optical Element (DOE)
532nm Rectangular Flat-Top Beam Shaping Diffractive Optical Element (DOE)
By means of microstructures, the transmission phase of light passing through the diffractive optical element (DOE) is altered, thereby enabling phase modulation of the incident light. This causes the light to be dispersed into different diffraction orders. Leveraging this characteristic, by configuring the diffraction orders and object distances, interference occurs at a given plane (typically at infinity or the focal plane of a lens), resulting in a specific light intensity distribution.
This high-performance Diffractive Optical Element (DOE) is specifically engineered for 532nm green laser applications. It transforms standard Gaussian laser beams into a precise, 380 µm × 150 µm rectangular flat-top spot with steep edge profiles and uniform energy distribution.
Designed with a 16-level phase profile, this beam shaper achieves exceptional total diffraction efficiency (>90%) and energy uniformity (>90% RMS), effectively eliminating hot spots and reducing thermal damage during precision laser processing.
The DOE comes in a standard Φ25.4 mm (1-inch) outer diameter with a Φ15 mm clear aperture, ensuring seamless integration into most optical mounts and filter wheels.
