Abstract
A light intensity modulator with a predefined range of modulation wavelengths (preferably a narrow range) can be adjusted by a control signal. This modulator receives a light beam and retransmits a modulated light beam in which any wavelength within the modulation range is modulated. A light intensity detector receives this modulated beam and outputs an electrical signal which is a function of the luminous intensity detected. Such a device finds particular application as a spectrophotometer.
