APEquamm provides refractive 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 refractive 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%.

Customised refractive diffusers can be used to create highly arbitrary intensity distributions specific to an application. Examples of intensity distributions include tridents, ramps and skewed Gaussians whilst spatial distributions can include triangles, arcs and more.

1.Gaussian Diffusers

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.

2.Flat Top Diffusers

The edge steepness and flatness of the focused spot can be easily customized by supplying desired Supergaussian parameters to maximize system performance. Numerous spot shapes can be achieved including circular, square, annular and more.

3.Custom Diffusers

Customised diffusers can be used to create highly arbitrary intensity distributions specific to an application. Examples of intensity distributions include tridents, ramps and skewed Gaussians whilst spatial distributions can include triangles, arcs and more.
