We describe a design method to athermalize a single-material lens element by using a kinoform on one surface to keep its focal length and aberrations constant with temperature. We diamond turned and thermally tested a plastic athermat and compared it to an uncompensated conventional lens.

Dense or glassy active matter, as a result of its remarkable resemblance to passive glass-forming materials, is enjoying increasing scientific interest. To better grasp the subtle effect of active motion on the process of vitrification, a number of active mode-coupling theories (MCTs) have recently been developed. These have proven capable of qualitatively predicting important parts of the active glassy phenomenology.
