Design and implementation of a new freeform surface based on Chebyshev polynomials

A 2D freeform surface in OpticStudio® based on Chebyshev polynomials enables greater flexibility in the design of freeform optics and facilitates various manufacturing techniques.

Learn how:

  • Designs use this freeform surface, including a reflector for generating uniform illumination from Gaussian input and a TMA telescope.

  • The Chebyshev surface yields equivalent or superior results to the XY polynomial and Zernike surface descriptions for better manufacturability.

  • The Chebyshev polynomial surface supports varying degrees of asymmetry, which can be helpful when the final design form is not known at the start of the optimization process.
