In this post we will review textbooks, online tutorials, discussion forums like the ELE Optics Community and software training programs like Zemax training and other great sources to help engineers learn lens design from basic concepts to advanced techniques.
Projection systems are one of the most common consumer optical devices (probably second to photographic systems). They allow us to view images on a screen (usually) by magnifying and projecting them at distances from a few centimeters to several meters away...
Introduction to RMS Wavefront Error As mentioned in several articles in this blog, aberrations are of great relevance when designing an optical system. The objective being to design a system that creates a “good image”. However, there are different metrics to...
Introduction Optical relays, an integral component of various optical systems, play a crucial role when the user's proximity to the observed object is limited or when specific image transformations are required. A prevalent example of this is found in relay lenses,...
Simulating any optical system in Zemax is a fundamental part of our optical design process. Among many reasons, we simulate in Zemax so we can evaluate the optical performance, whether in terms of aberrations for imaging systems or power efficiency for...
A key aspect of an optical product development is the creation of a quality optical system design optimized to reduce aberrations and system cost. In an attempt to reach a balance between cost and performance, optical designers have created lenses with different...
To assist with the computation of the paths of millions of light rays, optical engineers use specialized software to design and simulate optical systems. Zemax is the most popular optical design software and the one I prefer. It includes many built-in functions...
LightFair International (LFI) is the premier lighting exhibition in the US and it draws thousands each year. LFI is equal lighting education and product showcase with the first half of the conference filled with panel discussions, keynote events, and seminars with...
