Abstract

In a lens system a temperature change has the effect of changing the index of refraction and the geometry of the lens elements. In addition, after a temperature change the lens takes some time to stabilize. As a consequence the optical properties of the nominal lens system change. We review the concepts of the opto-thermal coefficient and of the thermal diffusivity, and provide a method for their rapid calculation in lens design software. We also provide tables of these coefficients that are needed in a lens tolerancing analysis.
