其他摘要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 of double spectrometers,which is especially suitable for portable instruments.One slit is replaced by the double-slit,than two beams of spectrum can be detected.The working principle and design requirement of double-beam spectrometer are described.A spectrometer of portable spectrophotometer  is designed by this method.A toroidal imaging mirror is used for the Czerny-Turner double-beam spectrometer in this paper, which can better correct astigmatism,and prevent the dual-beam spectral crosstalk.The results demonstrate that the doublebeam  spectrometer designed by this method meets the design specifications,with the spectral resolution less than 10nm,the spectral length of 9.12mm,and the volume of 57mm×54mm×23mm,and without the dual-beam spectral overlap in the detector  either.Comparing with a traditional spectrophotometer,the modified spectrophotometer uses a set of double-beam spectrometer  instead of two sets of spectrometers,which can greatly reduce the volume.This design method can be specially applied in portable spectrophotometers,also can be widely applied in other double-beam spectrophotometers,which offers a new idea for the design of dual-beam spectrophotometers.
