Best for Freeform optics represents
Freeform optics represents a group of surfaces that are not limited by symmetry or equation. Surfaces can be represented in different ways from polynomial equation to zernike coefficients or points cloud. The optics of freeforms allows the optical designer the highest flexability and can lead to the design of a system with better optical performance while saving on size and weight.
The manufacturing of freeform elements is challanging in both surfacing and measurements and requires extensive knoledge and the usage of compatible tools of hardware and software. SPO holds knowledge of more than 20 years in the production of freeforms.
