Abstract
This paper presents design of a multichannel spectrophotometer, which uses a holographic concave grating as dispersive element. The flat spectral field of the grating generates the integration of collimation, disperse and convergence. Meanwhile, a CCD with 2048 pixels is placed on the spectral plane as a multichannel photodetectors so that the system can eliminate mechanical scanning. Due to the features of those elements and design procedure, the spectrophotometer shows more advantages that the structure of the new typed spectrometer becomes smaller, its stability, reproducibility and the rate of measurement have been much more increased.
