國際標準光源最常見的就是D65，這是一種模擬日光的人工光源。國際標準化組織規(guī)定了D65標準光源觀察環(huán)境中所使用的人造光源的光譜要求，感興趣的朋友不妨來了解一下！

什么是標準光源光譜？

光譜功率分布是指光源中各個波長的色光的輻射功率按照波長的分布的。光源的顏色特征就是有光譜功率分布決定的。不管是自然光源還是人造光源大都是由單色光組成的復色光。光源的輻射能按波長分布的規(guī)律隨著光源的不同而變化。設以波長λ為中心的微小波長寬度dλ范圍內的輻射量為dX，則單位波長問隔所對應的輻射量稱為光譜密度Xλ，即Xλ=dX/dλ。

式中的輻射量可以是輻射通量、輻射強度、輻射亮度、輻射照度等。一般而言．波長不同，其對應的光譜密度也不同。將光源的光譜密度與波長之間的對應關系用函數(shù)來表示時，稱此函數(shù)為該光源的光譜分布Xλ(λ)。
