ABSTRACT:
An optical device including an optical bench and a plurality of optical elements. The optical bench has first and second supporting sections, separated from each other, each having at least two supporting surfaces. The optical elements secured to the first and second supporting sections have cylindrical bodies, so that these optical elements contact the sections only by lines. Therefore, the relative positions of each optical elements in the optical device are maintained for a long time without being affected by temperature variation in the atmosphere surrounding the optical device.
