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.
