| 摘 要： | 光学系统是分光光度计的核心部分,以光谱仪基本原理和光学设计理论为基础,以便携化、低成本、且满足设计要求的光谱范围和分辨率为具体设计目标,对李特洛系统、艾伯特-法斯梯系统、切尔尼-特纳系统、交叉式切尔尼-特纳系统这4种可行的设计方案进行了比较与分析,提出以平面衍射光栅作为色散元件的非对称交叉式C zerny-Turner结构作为该设计的系统结构。用光学软件对该系统进行模拟和优化,设计结果表明:设计的系统光谱范围为360 nm～740 nm,光谱分辨率为10 nm、F数为5.25、光谱展开为44.1 mm、系统体积约80 mm×69 mm×62 mm,满足精度高、体积小及成本低等设计要求。

| Abstract: | Optics is the key part of a spectrophotometer,which directly affects system performance and accuracy.With portable,low cost,appropiate spectral range and resolution requirements as design target,the crossed Czerny-Turner structure based on plane diffraction gratings was proposed based on the operation principle of spectrophotometer and the theory of optical design.Comparison of some feasible design solutions were made,which included Littrow system,ebert-Fastie system,Czerny-Turner system and crossed Czerny-... |
