style="text-indent:25px">照度儀形成視覺影像。人眼中的感光細(xì)胞有兩種：錐狀細(xì)胞和桿狀細(xì)胞，其中錐狀細(xì)胞對(duì)不同色彩的光有不同的敏感度，對(duì)波長550nm的光很敏感。通常要求的亮度至少為每平方米幾個(gè)坎德拉，所以也常稱為明視覺。而桿狀細(xì)胞不能辨別色彩，對(duì)波長為510nm的光很敏感，所需的亮度一般低于每平方米百分之幾坎德拉，所以也常稱為暗視覺。中間視覺介于上述兩種視覺之間。日常生活中，不同的照明、顯示光源具有不同的光譜特性，如白熾燈光譜在550-780nm分布較多，而熒光燈光波在短波區(qū)域分布較多。</p><p style="text-indent:25px">品質(zhì)控制，健康防治及各種環(huán)境中的光照照度測量，如工廠、學(xué)校、辦公室、交通路線、家庭等各種場合。照度計(jì)的注意事項(xiàng)①光電池應(yīng)用直線性好的硒(Se)光電池或硅(Si)光電池；長時(shí)間工作仍能保持良好的穩(wěn)定性,且靈敏度高；高E時(shí)選用高內(nèi)阻的光電池,其靈敏度低而線性好，受強(qiáng)光照射不易受損。②內(nèi)付有V(λ)修正濾光片,適宜用異色溫光源的照度，誤差小。③光電池前加一塊余弦角度補(bǔ)償器(乳白玻璃或白色塑料)原因是入射角大時(shí),光電池偏離余弦定則。照度計(jì)的靈敏度會(huì)因使用條件或時(shí)間而降低。</p><div

style="text-indent:25px">照度計(jì)偏重波長較長的的紅色系高壓燈，或波長較短藍(lán)紫色系如Daylight日光燈；也有分布比較平均的如白熾燈泡系列，同一照度計(jì)對(duì)不同的波長其靈敏度可能略有不同，故適度的補(bǔ)償屬必要。余弦補(bǔ)償﹝CosineCompensation﹞大家都知道，受照面的亮度與光源的入射角度有關(guān)。相同的道理，在用照度計(jì)做測量時(shí)，感應(yīng)器﹝Sensor﹞與光源入射角度自然會(huì)對(duì)照度計(jì)的讀值有影響。所以一個(gè)好的照度計(jì)是否有余弦補(bǔ)償?shù)墓δ軐?shí)在不可忽略。照度計(jì)如何校準(zhǔn)：校準(zhǔn)雖不同于檢定，但進(jìn)行校準(zhǔn)的人員也應(yīng)經(jīng)有效的考核。擴(kuò)大照度計(jì)的定標(biāo)量程可改變距離。廣東分量照度計(jì)使用</p><p
