LightFair, Fundamentals of Luminaire Design.
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 topics ranging from aesthetic lighting design to detailed lighting controls. As part of an […]
Expanding Zemax Capabilities with User Defined Objects
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 and objects but sometimes more specific objects are required. Zemax therefore allows user […]
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 […]
How Aspheric and Freeform lenses work
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 shapes that help reduce aberrations. Traditionally, optical elements have radial symmetry: they are […]
Top 12 Resources for Mastering Lens Design: A Comprehensive Guide
Introduction Lens design is undeniably a complex and challenging field of study, characterized by its intricate blend of physics, mathematics, and engineering principles. Becoming a truly proficient lens designer isn’t merely a matter of acquiring theoretical knowledge; it necessitates years of hands-on practical experience and a keen understanding of how to apply theoretical concepts to […]
Mastering Relay Lens Design: Enhancing Optical Systems | OFH
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, often employed in scenarios where physical closeness to the object is impractical, as seen […]
