    摘要: A reference wavelength light generating apparatus is disclosed in which light emitted from a light source is branched by a light branching unit, one of the branched lights is extracted as a measuring beam and the other is extracted as reference wavelength light by passing through a collimator and an absorbing member and then being reflected by a reflecting member to return to the branching unit.
