Design of Dual-Beam Spectrometer in Spectrophotometer for Colorimetry
Yi-xuan LIU, and Chang-xiang YAN
Spectrophotometers for colorimetry are usually composed of two independent and identical spectrometers.In order to reduce the volume of spectrophotometer for colorimetry,a design method of double-beam spectrometer is put forward.A traditional spectrometer is modified so that a new spectrometer can realize the function
