    Athermalized beam expanders are based on a Dall-Kirkham off-axis mirror design that incorporates INVAR elements to provide thermal stabilization from the UV to the IR. The achromatic, aluminum-coated elements feature a short focal length for durability and lower sensitivity to temperature changes over a temperature range of -40° to +50°C.
