The monitor unit includes: a second detector; and a light amount control unit. The light amount control unit is operable to control the infrared light source such that the amount comes closer to a target light amount, based on the signal. The infrared light source emits light having a first wavelength range and light having a second wavelength range different from the first wavelength range. The second detector includes: a first light detection element; and a second light detection element. The first light detection element outputs to the light amount control unit a first voltage corresponding to the light having the first wavelength range. The second light detection element outputs to the light amount control unit a second voltage corresponding to the light having the second wavelength range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spectrophotometer","description":"A spectrophotometer includes: an infrared light source; an interferometer; a first detector; and a monitor unit.
