宽波段多功能自动光谱辐射计的研制

The Development of a Versatile Automatic Spectroradiometer in Broad Wavelength Band

本文介绍一种新型自动光谱辐射计,以C-G 型光栅双单色仪为核心,利用电子计算机进行控制和数据处理。仪器能自动地测量白炽灯、气体放电灯和谱线灯的光谱能量、色温和显色指数,并且可以测量各种光接收器的相对光谱灵敏度分布,具有功能多、自动化程度高、宽波段连续测量和用途广等特点。仪器重复测量精度优于±1%(紫外和红外光谱端除外)。

A novel automatic spectroradiometer which incorporates a C-C typegrating double monochromator as its main unit and an electronic computer for operationcontrol and data processing is described in this paper.Characterized by high versati-lity,fully automated continuous operation in a broad wavelength band and extensive ap-plications,it can be used to measure,in an automatic way,the spectral radiant emi-ttance,colour temperature and colour rendering index of incandescent and gas dischargelamps as well as the relative spectral sensitivity of various photo detectors.The measuringrepeatability is better than±1%(excluding the extreme working ends in both the UVand IR regions).
