摘　　要：本文研究了便携式光谱光度计的光学系统及各光学元件参数的设计方法.选择了消除像差的非交叉对称式Czerny-Turner（切尔尼-特纳）结构,分光系统采用平面光栅为分光元件,球面反射镜为成像物镜.设计出了具有良好特性,频谱范围为380~760nm,分辨率可达3nm的光谱光度计.The optical system of the Portable spectral photometer is researched and element parameters are designed.The symmetry Czerny-turner optical system which can greatly eliminate the aberration by optimizing the optical path is adopted.The optical system of the spectral photometer is introduced by taking a plan grating as a beam splitter and a spherical mirror as an imaging objective.The spectrometer with good characteristics,spectrum range of 380 ~ 760 nm,and the resolution 3nm is designed.
