Achromatic Shaping Solution with High Efficency
BD (Broadband Diffusers) are special beam shaping micro-refractive diffusers, dedicated to high power applications where multi-wavelength laser is used in the same optical path.
Typical applications are in the fields of aesthetic medicine where a few wavelengths are used for different procedures, microscopy applications with broadband wide spectrum sources, laser display projection (cinema), and some very specific scientific applications.
A special manufacturing process that was developed in our company allows Holo/Or to make quick and affordable custom shapes and angles of the BD with delivery time comparable with diffractive diffusers. The BD element can be used in the same optical setups as a diffractive diffuser element.
Designed using innovative modified fractal algorithms, the BD delivers some additional advantages such as:
- Same performance for wide wavelength spectrum from IR to UV.
- High efficiency
- No Zero Order
Comparison table: BD vs. Diffractive Diffuser

|Efficiency||>90%||Typical 80%, up to 95%|
|Shaping flexibilty||limited to basic shapes:round,line and rectangles||Any shape and profile|
|Suitable for wafer mass production||Yes||Yes|
