Tailored Diffusers

15 Jun 2017

LASER COMPONENTS, alongside partners Holo/Or, offers a number of solutions for

beam homogenising and shaping. Using a beam homogeniser DOE, a collimated

input beam can be converted in to a well-defined beam with a homogenised intensity

profile. Custom spot shapes for user-defined wavelengths are possible. Beam

homogenisers are useful in a large number of applications which require a welldefined

spot shape and a randomly diffused intensity profile.

Holo/Or have recently developed new algorithms for the design of custom diffusers

for use in heat treatment applications. Such applications often require the illumination

profile to be very smooth, without the characteristic intensity spike in the centre caused

by zero order. A steep transition region, i.e. sharp edges to the spot profile is also

useful to ensure accurate energy doses when scanning the spot across a surface

without overlap. New methods make these characteristics achievable even for large

angle diffusers, tailored specifically for custom requirements.
