Optical design has traditionally required large amounts of complex calculations to be performed. This can now be automated.

Researchers have developed a program for outputting high-quality freeform optical systems that simply requires basic optical design knowledge
In this whitepaper, we introduce a novel optical replication manufacturing method. We investigate the manufacture and measurement of freeform optics, explain how this high-precision replication manufacturing method works, and outline the benefits this manufacturing solution brings to OEMs and any organisation who wants to benefit from the inclusion of freeform optics at cost and at scale across their imaging applications.
Aspheric lenses are an extremely powerful tool for improving the performance of optical systems whilst also reducing the number of elements and consequently size and weight. It is important to understand, however, that aspheric optical components have their own set of specifications and manufacturing challenges. The use of sub-aperture grinding and polishing techniques create additional issues that need to be monitored and controlled to maximise the performance. Find out more about what to consider when specifying a high precision aspheric lens in the whitepaper from Edmund Optics.
