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...
Anyone who has peaked through a hotel room peephole has used a fish eye lens. Usually, the fish eye lens has a very short focal length (less than 15mm for a 35mm-size image sensor), but a large field of view (FOV). The latter can be as large as...
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...
模拟Zemax中的任何光学系统是我们光学设计过程的基本组成部分。在许多原因中，我们在Zemax中进行模拟，以便我们可以评估光学性能，无论是在成像系统的畸变方面还是...的功率效率...
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...
When integrating off the shelf lenses into optical systems, it is essential to have full information about how a lens will perform with other elements in the system. When multiple component vendors ( ie electronics, mechanical, optical) are involved, data...
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...
