阐述ＳＰＤ－Ｉ型全息凹面衍射光栅平场摄谱仪的基本工作原理和仪器结构，详细报导了该仪器的适用波长范围、平直谱面长度、倒数线色散率和光谱带宽等主要技术性能的光学测试方法和实验结果。测量结果表明在设计波长范围（４００至８００ｍｍ）内像差校正良好，获得的平直谱面可与光敏面长度为一英寸（２３．５ｃｍ）的多通道探测器相配；仪器的色散相当均匀（约１７ｎｍ／ｍｍ），在５７９．９６ｎｍ波长处测得的光谱带宽为１ｎｍ，能满足一般光学多通道分析仪的要求。
The basic working principle and instrument structure of the SPD-I holographic concave diffraction grating flat-panel spectrometer are described. The main technical performance of the instrument, such as the applicable wavelength range, flat spectral length, reciprocal line dispersion rate and spectral bandwidth, are reported in detail Optical test methods and experimental results. The measurements showed good aberration correction in the design wavelength range (400 to 800 mm), resulting in flat spectra matching multi-channel detectors with a one inch (23.5 cm) length of photosensitive surface; the dispersion of the instrument was fairly uniform About 17nm / mm), the spectral bandwidth measured at 579.96nm wavelength of 1nm, to meet the general optical multi-channel analyzer requirements.
