Optimizing an Infrared Lamp Heater

This article describes work I did to improve an existing infrared lamp heater in a so called horizontal geometry MOCVD reactor. Zemax was used to model and optimize the heater geometry using non-sequential ray-tracing.

How to Use the Stock Lens Matching Tool

The Stock Lens Matching tool will swap out the lenses in a design for the nearest equivalents in the selected vendors’ catalogs, and offers the potential to make great cost savings in the finished design by eliminating the need for custom manufacture. The tool will give great results, assuming that the design can work well with stock lenses. This may sound obvious, but most stock lenses are plano-curved or equi-curved, and so exist mainly at very specific shape factors. For this reason, you should use the tool with designs with modest field angles and narrow wavelength ranges, where these shape factors are appropriate.

How to Optimize Non-Sequential Optical Systems

This article gives a recommended approach to the optimization of non-sequential optical systems. The recommended methods are to use Pixel Interpolation, aggregate detector data (moment of illumination data) and the orthogonal descent optimizer. As an example, a free-form mirror is optimized to maximize the brightness of an LED from 23 Cd to >250 Cd in just a few minutes of optimization.
