Abstract

A spectroscopic measurement device emits light to a measurement target and measures the measurement light output from the measurement target in accordance with the light emission. A spectroscopic measurement device includes: a first housing having a light shielding property and configured to house a light source that emits light and having a first opening through which the light emitted from the light source passes; a second housing having a light shielding property and having a second opening through which the measurement light passes and configured to house a spectrometer that receives the measurement light that has passed through the second opening; and an arm member configured to relatively rotatably join the first housing and the second housing. A proximal end side of the arm member is rotatably joined with the second housing. The first housing is attached to a distal end side of the arm member.
