Beschreibung
Zusammenfassung:	A surveying instrument including an optical axis deflector which integrally deflects a distance measuring optical axis and a light receiving optical axis, a narrow-angle image pickup module having an optical axis a part of which is common to the distance measuring optical axis, a distance measurement calculation module and an arithmetic control module, in which the wavelength dispersion compensation prisms which is constituted of a plurality of optical members having the different wavelength characteristics are provided in the part of which is common to the distance measuring optical axis and the narrow-angle image pickup optical axis, the arithmetic control module performs the distance measurement of a measuring point based on a signal of the distance measuring light and a signal of the reflected distance measuring light, and acquires a narrow-angle image in which the dispersion has been compensated by the wavelength dispersion compensation prisms.
