PHOTOMETRIC DEVICE

WIPO Patent Application WO/2021/038730

A1

The purpose of the present invention is to provide a photometric device with which photometry can be performed from a distance. This photometric device 301 comprises: a light source 11 that generates a beam-shaped irradiation light L1; a beam control unit 12 for controlling the direction for emitting the irradiation light L1; a light condensing unit 13 that condenses a return light L2 generated due to the irradiation light L1 irradiating a portion of an object 50 to be measured; and a detecting unit 14 that detects information on the object 50 to be measured included in the return light L2 condensed by the light condensing unit 13. In this photometric device, the beam control unit can arbitrarily control the direction for emitting the emission light for photometry and the light condensing unit can efficiently receive faint return light from the object to be measured. Therefore, the present invention can provide the photometry device with which photometry can be performed from a distance.
