In this article, a wedged LCD backlight is modeled, analyzed, and optimized for illumination output criteria.

This article explains how to call a macro from within another macro, and how data are passed back and forth between macros.

There have been literally dozens of eye models published over more than 150 years, from very simple “reduced” eyes consisting of a single refracting surface to very complex models with more than 4,000 refracting surfaces. This article presents several sequential and non-sequential models of the human eye in ZEMAX format, with glass catalog data.

Veiling glare is a term that is often used in the field of imaging system design. Technically, veiling glare is stray light that reaches the sensor plane of an imaging system, and it can cause a decrease in the imaging system’s performance.

Often,  a full non-sequential treatment is needed for accurate results. However, for many optical imaging systems, a first-cut look at forward scattering effects is all that is really required. This article will show how to make just such a preliminary veiling glare measurement using tools that are already built into ZEMAX. This analysis will require just a few minutes to perform, and will give very useful results.

In this article, we will create model of a human eye in ZEMAX using the Liou & Brennan 1997 eye model. After successfully generating this eye model in ZEMAX, we will use it to design a free-form progressive eyeglass lens.
