Abstract
An apparatus for collimating or focusing a coherent light beam without beam misalignment or beam focal point drift due to thermal deformation. The apparatus includes an optical component made of a material having an optical coefficient of thermal expansion and an optomechanical component having an optical support configured to hold the optical component. The optical support is made of a material having an optomechanical coefficient of thermal expansion, wherein the optical coefficient of thermal expansion and the optomechanical coefficient of thermal expansion are selected such that the optical component and the optomechanical component expand or contract as a single entity under varying temperatures.
