Improving Optical Free-Form Production

Facebook Twitter LinkedIn Email Comments

Combining steps on one machine enables precision production of free-form optics.

Michael Thomas and Dr. Michael Sander, Satisloh GmbH

Production of free-form optics is one of the most challenging areas in the precision optics industry, creating continuously increasing demands on the machine manufacturers. Free-form optics include rotationally symmetric parts, such as aspheres and parabolic mirrors, which are common components in state-of-the-art optical instruments. Significantly greater challenges are presented by nonrotationally symmetric parts, such as complex beam-shaping elements or off-axis head-up display mirrors. Figure 1. Nonrotationally symmetric optical free-form optics (surface shown here) are particularly...Read full article
