Optical device and single lens reflex camera
An optical device for forming an image of an object, comprising: a semitransparent mirror surface disposed on an optical path of the image of the object; and a light projection unit configured to project light to the semitransparent mirror surface and thereby to combine, on the optical path, the projected light transmitting through the semitransparent mirror surface with the image of the object reflecting from the semitransparent mirror surface, wherein: a first wavelength region is defined in a visible light region to include a wavelength of the projected light; the semitransparent mirror surface has a substantially flat reflectance property within a second wavelength region which is defined in the visible light region not to include the first wavelength region; and transmissivity of the semitransparent mirror surface at the wavelength of the projected light is higher by 10% to 50% than transmissivity in the second wavelength region.. .
