High-efficiency refractive optical elements Micro-optical structures for complex optical tasks
Refractive optical elements (ROEs) refract light thanks to microstructured surfaces and functionally resemble familiar conventional lenses and prisms. Thanks to the extreme miniaturization of corresponding functionalities of refractive macro optics, ROE enable very compact, lightweight and elegant, optical solutions.
Smart solutions for your application
Refractive micro-optical elements miniaturize well-known conventional macro-optics. The functional definition is largely based on their surface topography profile. The asymmetrical profiles have flexible and high optical functionalities. They are combined with a high level of efficiency, a wide angular spectrum and a high degree of homogeneity.
We adapt our technology for your specific application and design precise mono- and achromatic solutions for you.
