Abstract
Abstract A MOUNT FOR AN OPTICAL ELEMENT (FOR EXAMPLE A CONCAVE ELLIPSODIAL MIRROR) INCLUDES A PLUG FOR FIXING IN SPACE THE OPTICAL CENTER OF THE ELEMENT, WHILE ALLOWING TILTING OF THE ELEMENT FOR ANGULAR ADJUSTMENT. THE OPTICAL ELEMENT IS RESILIENTLY BIASED AGAINST THIS PLUG, AND IS ADJUSTED BY A SINGLE SCREW EACH FOR HORIZONTAL AND VERTICAL TILT. THIS ELIMINATES ADJUSTMENT OF THE OPTICAL ELEMENT NOT ONLY IN ITS OWN PLANE, BUT ALSO ALONG ITS OPTICAL AXIS FOR FOCUSING.
