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 […]
Aviation Light Optic Design
Aviation Light is a critical component in ensuring the safety and efficiency of air travel. In the last month, I have had the need to travel several times by airplane. So, after several hours enjoying $15 sodas and $30 hamburgers at the airport gates, I started paying more attention to the different aviation light systems […]
Understanding STVZO Bike Light Pattern and Optical Design
STVZO (Straßenverkehrs-Zulassungs-Ordnung) is one of the most critical standards in the realm of bicycle lighting, ensuring compliance with legal requirements while enhancing the safety and convenience of cyclists. Adhering to these stringent standards is essential for providing effective illumination and meeting the necessary regulations for bike lights. Designing an STVZO-compliant light involves a deep understanding […]
How does a light pipe overmold work?
One common production method for light pipes is the overmold . This method uses an inexpensive light diffused plastic overmolded with a black case to generate a light-pipe. The “Win” keyboard key is one good example. “Win” key appearance to the observer. The black key body has a hole; during manufacturing, this hole is filled […]
Optimized Solutions for Underwater Optics Design
Underwater optics play a crucial role in the design of underwater camera lenses, where a large number of variables come into play. As with every optical system design, the selection of cameras, lenses, housings, and operational parameters greatly influences the performance of the complete system. Determining the correct combination of components is what experienced optical […]
Variable spot size + color mixing optical system
In applications like concert show lighting, architectural lighting, and cinema projection, achieving good color mixing and variable spot size is essential. The optics design in front of a RGBW LED source must include optimization for color uniformity as well as beam shape. A common solution is to place diffuse materials in the optical path. This […]
