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.
