Description: Free-form-optics offer the ability for creating tailor made radiant intensity or irradiance distributions, which cannot be achieved using conventional optical lenses. Our self-developed calculation algorithms allow the calulation of very flat (10-200 µm) free-form micro-optical elements (FF-MOEs) with comparable optical functionalities as conventional voluminous FF lenses.
- Self-developed algorithms offer the highest degree of flexibility to develop tailor made optical components for arbitrary optical problems.
- FF-MOEs have the functionality of conventional voluminous FF optics and conventional optics, but whose maximum height is freely scalable in the range 5 – 200 µm.
- The very low height of the structures enables the use of alternative manufacturing methods such as e.g. the grayscale laser lithography for the fabrication of master structures or the roll-to-roll process for mass production.
- Through an iterative interaction between the computational algorithm and ray-tracing simulations, the calculated FF-MOEs can be optimized within the whole optical system.
- The light management capabilities of FF-MOEs have already been tested for various topics and applications e.g. direct lit applications, sensor applications, logo projection, wall-wash applications, generation of tailor made radiant intensity distributions, etc.
