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
