Polychromatic or Multichannel Broadband Diffuser

Many laser-based systems, especially in the lifesciences, projection and projection mapping fields, require the use of more than a single wavelength high power laser on the same optical path to achieve the desired functionality. To meet this need, Holo/Or has developed the high-power Broadband Diffuser (BD). The BD, is a micro-refractive diffuser, specially designed to give an optimal shaping solution to high power applications where more than one wavelength is required. It converts an incident single or multi-mode beam into a well-defined flat-top round, rectangular or line shape. The BD is fabricated of pure Fused-Silica to endure high LDT, provides the same performance for a wide wavelength spectrum from IR to UV, has high efficiency and no zero-order. BD can ideally be implemented in Multi-Channel systems where there is more than one laser on the same optical path or in Tunable laser systems, and is especially suitable for high efficiency shaping of multi-mode high power lasers such as UV excimer and IR fiber coupled stacks/bars.
