ABSTRACT
Various devices and elements are utilized for the handling of optical elements and the operation of light tuned to a target experiment. With infrared light and ultraviolet light outside the visible light range, some visible light other than the wavelength to be used transmits through it or a special specifi cation for capability to withstand high output is used. Optical elements such as lenses, prisms, and mirrors are not used in naked style, but are handled after being placed in a frame for holding and fi xing by suitable means. Articles corresponding to this frame are mounts and holders. An optical bench and a tabletop are used for disposing and fi xing the optical element placed in the holder according to the purpose of the experiment, and a vibration isolation stand is used to perform experiments under stable conditions, without being affected by vibrations and other disturbances.
