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 Lens Design
by Victor Argueta | Jun 23, 2021 | illumination lens design, lens design, optical design, Zemax
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...
Using RMS wavefront error to evaluate optical quality
by Victor Argueta | Jan 27, 2021 | optical design, optics, optics definitions, Zemax
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 evaluate what is a “good...
Fundamentals of Relay Lens Design
by Victor Argueta | Dec 3, 2020 | FAQ, lens design consulting, Zemax
A common optical system is relay lenses. Relay lenses are used when the user cannot be physically close to the object being observed (like an endoscope) or when images need to be inverted/rectified (like in a telescopic sight). Here we describe some steps that...
Benefits of Multiphysics Design
by Victor Argueta | Nov 18, 2020 | mechanical design, optical design, opto-mechanical design, Zemax
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...
How Aspheric and Freeform lenses work
by Victor Argueta | Nov 9, 2020 | lens design, OFH, optical design, Zemax
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...
Expanding Zemax Capabilities with User Defined Objects
by AnatoliTrafimuk | Jun 12, 2015 | illumination, optical engineering, Zemax
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...
Fundamentals of Luminaire Design, LightFair
by John | Nov 18, 2014 | illumination, LED, Zemax
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...
