Abstract
An optical system and optical apparatus prevent degradation of the S/N ratio due to switching between OCT and OCM observation modes and attain a high S/N ratio in both the observation modes. The optical system includes a light sourceand a light-branching memberfor branching light from the light sourceinto a reference light path and a signal light path. An objectiveis placed in the signal light path. A light-scanning systemscans light in the signal light path with respect to a sampleplaced in the signal light path. A beam diameter changing optical systemchanges the beam diameter of light entering or exiting the light-scanning system. A light-combining membercombines together the reference light path and the signal light path. A light-detecting elementdetects light combined by the light-combining member
