光谱仪:AS7341光谱传感器、AS7343光谱传感器、DIY自制光谱仪、HPCS320光谱仪[已校准]
测试样本:太阳光(晴天)
对照HPCS320光谱仪的光谱数据分析,可以看出AS7341光谱传感器的光谱数据的红外波长(700nm-900nm)明显过高,其余部分数据有明显的凹陷,还有AS7343光谱传感器的光谱数据部分也有明显的凹陷,中间可能采用插值算法。至于DIY自制光谱仪光谱图上看较准确,但导出的光谱数据不是按光功率匹配,而是参照虹谱强度百分比计算的,准确度有一定差别。
然后计算显色指数,得出:
HPCS320Ra为99.0326757592
AS7341光谱传感器Ra为96.534358933
AS7343光谱传感器Ra为95.6717591664
DIY自制光谱仪Ra为96.0103086128
