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.

it is imperative to recognise the nuances of optical manufacturing, paying careful attention to the statistical assumption of models and manufacturing practicality

Surface flatness is a critical parameter for many laser systems but also a key cost driver. In this paper we explore the effect it can have on the focused spot size in a laser material processing system

Laser Induced Damage Threshold (LIDT) is a critical parameter when selecting or specifying laser optics. Underspecifying LIDT can lead to catastrophic component failure in the lab or field, risking the performance of critical equipment.
