A colorimeter is a device that measures the absorbance of particular wavelengths of light by a specific solution. A spectrometer, on the other hand, is a scientific instrument used to split light into a spectrum in order to produce spectral lines and measure the resulting wavelength intensities. An imaging colorimeter and spectrometer is a device that allows for spectrally resolved colorimetry measurements, as it effectively combines the technology of camera imaging based on colorimeters and spectrometers. By combining two fundamentally different devices, this technology offers unprecedented capabilities and flexibility.
