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
