PowerPhotonic’s Psuedo Random Intensity Mapping Element (PRIME) flat-top diffusers use a unique freeform direct-write process to fabricate a highly non-uniform surface in fused silica.
These quasi-random optics are designed to impart a well-defined and tightly controlled divergence angle which can range from fractions of a degree up to 10 degrees (FWHM) with potential transmission efficiencies in excess of 99%.
The Gaussian properties of the focused spot can be easily customized by supplying desired parameters to maximize system performance, creating both supra- and super- Gaussian distributions.
