The Ultimate Benefits of Multiphysics Design You Need to Know
Multiphysics simulations are a fundamental part of our optical design process in Zemax. We use these simulations to evaluate optical performance, whether in terms of aberrations for imaging systems or power efficiency for non-imaging systems. The Importance of Multiphysics Simulations in Optical Design There are situations however in which a purely optical simulation is not […]
Is higher sensor resolution always better?
An optical system is only as strong as its weakest link. When designing an imaging system, sensor resolution is just one important factor and it is important to ensure sensors and detectors are well matched. Take these scenarios: In the simplest terms, the above are all composed of an object, an imaging object or lens, […]
Design considerations for microlenses and lensarrays
As optical systems are reduced in size, we encounter new engineering challenges when analyzing and designing lenses. These are issues that we usually don’t see when working with larger elements. This article will review some of the challenges when designing microlenses. A small lens is roughly defined as a lens with a diameter lower than […]

M squared and designing laser beam optics
There are different ways to calculate the quality of a laser beam. In general, we want our laser beam to be as close to a theoretical Gaussian Beam as possible. The question then is how do we measure the profile of our beam and how do we compare it against our ideal Gaussian Beam? First, […]
