摘要：

An imaging spectrometer instrument based on a prism-grating-prism (PGP) element as the dispersive component and advanced camera solutions for on-line applications are presented. The PGP element uses a volume type holographic plane transmission grating made of dichromated gelatin (DCG). Currently, spectrographs have been realized for the 400-1050 nm region but applicable spectral region of the PGP is 380-1800 nm. Spectral resolution is typically between 1.5 and 5 nm. The on-axis optical configuration and simple rugged tubular optomechanical construction of the spectrograph provides a good image quality and resistance to harsh environmental conditions. Spectrograph optics are designed to be interfaced to any standard CCD camera. Special camera structures and operating modes can be used for applications requiring on-line data interpretation and process control.
