Lenses and optics

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

Automating optical design

Researchers have developed a program for outputting high-quality freeform optical systems that simply requires basic optical design knowledge

How to manufacture low-cost freeform optics for high-volume imaging applications

This article is brought to you by: 

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.

Asphere Specifications and Optical Performance

This article is brought to you by: 

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.

Collimated Top Hat Cube

Holo/Or’s new single element collimated beam shaper, the Top Hat Cube, is a 25mm cube element that can shape any 3mm input beam into a collimated square or round top hat beam
