國(guó)際標(biāo)準(zhǔn)光源最常見(jiàn)的就是D65，這是一種模擬日光的人工光源。國(guó)際標(biāo)準(zhǔn)化組織規(guī)定了D65標(biāo)準(zhǔn)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(lái)了解一下！

什么是標(biāo)準(zhǔn)光源光譜？

光譜功率分布是指光源中各個(gè)波長(zhǎng)的色光的輻射功率按照波長(zhǎng)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(fù)色光。光源的輻射能按波長(zhǎng)分布的規(guī)律隨著光源的不同而變化。設(shè)以波長(zhǎng)λ為中心的微小波長(zhǎng)寬度dλ范圍內(nèi)的輻射量為dX，則單位波長(zhǎng)問(wèn)隔所對(duì)應(yīng)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(qiáng)度、輻射亮度、輻射照度等。一般而言．波長(zhǎng)不同，其對(duì)應(yīng)的光譜密度也不同。將光源的光譜密度與波長(zhǎng)之間的對(duì)應(yīng)關(guān)系用函數(shù)來(lái)表示時(shí)，稱此函數(shù)為該光源的光譜分布Xλ(λ)。
