Continuing to expand its capabilities to serve the growing and diverse needs of its customers, DILAS announced today at Photonics West 2011, that it is now producing solutions for homogenized areal illumination.
Homogenization of radiation becomes more and more important in thermal and medical applications. DILAS is using active mixing of the laser radiation with crossed micro-lens-arrays (MLA’s), resulting in a defined rearrangement of the light. This concept is an ideal solution for medical applications such as hair removal or dermatology, as well as for thermal treatments in industrial processes.
This innovative process leads to a uniformity of up to >95% with steep edges and no spikes in a square-shaped 12 x 12 mm² spot with defined working distance (62mm).
The square-shape is best for rasterization of larger areas with no overlap and very high coverage of the area. Other geometries are available upon request according to customer specifications.
The homogenization optics is suitable for a variety of fast-axis collimated diode laser beams and it can be attached to various DILAS products like the 12-bar water-cooled stack, delivering up to 1kW pulse power in the millisecond range and ideal for integration into a hand piece for hair removal due to its compact size.
Attached to any of DILAS’ conduction-cooled high-power multi-bar-modules, various homogeneous line geometries can be generated for thermal transformation processes e.g. in thin-film photovoltaic applications.
