This article explains how to fit the observed temperature variation of discrete (e.g. experimental) refractive index data to the ZEMAX thermal model.

This article demonstrates the thermal modeling capabilities available both in the EE and SE versions of ZEMAX. The sample files can be donwloaded from the last page of this article.

This article is also available in Japanese.

This article explains how the TCE column in the Lens Data Editor is used to model optical mounts between lenses.

This article demonstrates how the mechanical reference for the  lens mount can be arbitrarily changed.

On certain surface parameters, ZEMAX does not allow the placement of a thermal pickup solve. This article explains why.
