Introducing aspheric lenses in optical design broadens the horizons of possibilities and opens up new way to correct aberrations or creating effects that are not possible otherwise. Manufacturing these aspheric surfaces has come a long way during the

Freeform surfaces enable numerous new applications. However, they imply new challenges as well. Due to lots of degrees of freedom, it is possible to compensate some tolerances for each other.

Due to the improving manufacturing processes, freeform surfaces become a serious option within the optical design process. The work presented here was done within the German Regional Growth Core fo+ and involves all steps from optical design to manuf

Other than for spheres the decenter of an aspheric surface cannot be compensated for by further tilting. During tolerancing process of an optical system it is usually assumed that the surface form deviation, the wedge and tilt of a surface have the s

Manufacturing optical components relies on good measurements and specifications. One of the most precise measurements routinely required is the form accuracy. In practice, form deviation from the ideal surface is effectively low frequency errors, whe

For 10 years there has been the asphere as one of the new products to be accepted by the market. All parts of the chain design, production and measurement needed to learn how to treat the asphere and what it is helpful for. The aspheric optical eleme

In the last 10 years aspheres have readily gone from new products and specialized components to wide acceptance in the market. Successful fabrication of aspheres requires all parts of the process chain including design, production, and measurements.

We present designs using a 2-D freeform surface based on Chebyshev polynomials, whose description have been incorporated into Zemax OpticStudio. The designs analyzed include a reflector for generating uniform illumination as well as a TMA telescope.
