什么是等溫黑體：等溫黑體本身已經(jīng)形成空腔，腔體內(nèi)表面發(fā)射率的已經(jīng)經(jīng)過特殊工藝處理均勻一致，溫度均勻性也好。假定等溫黑體空腔內(nèi)溫度不均勻時(shí)，情況又如何 </p> <p> 呢？下面進(jìn)行詳細(xì)的理論分析。 </p> <p> 將園柱形空腔分為3個(gè)區(qū)域，腔底、腔口和腔壁。這里假設(shè)比較大溫度差異為20～40℃，其計(jì)算結(jié)果為平均溫度為300℃（腔內(nèi)極限溫差為20℃），在0.665μm波長處，當(dāng)量溫度為302.01℃；?5μm當(dāng)量溫度為300.18℃；隨著波長的增加，當(dāng)量溫度基本等于算術(shù)加權(quán)平均值300℃。在平均溫度1100℃時(shí)（溫度差異40℃），0.665μm的當(dāng)量溫度為1101.3℃，與平均溫度差1.3℃；0.8μm以后，當(dāng)量溫度基本為1100℃，與平均溫度已經(jīng)接近。上海蕓尖智能科技公司黑體爐均為等溫黑體空腔，溫度均勻性很好，等溫黑體溫度腔內(nèi)溫度差異很小。腔口發(fā)射能隨波長分布均勻，完全可以看作光譜輻射能量符合普朗克定律。用等溫黑體檢定輻射溫度計(jì)，只要等溫黑體工作正常，因工作波長的不同所帶來輻射溫度測量的差異，完全可以忽略不計(jì)。 </p> <p> <br /> </p><p style="text-indent:25px">小面源黑體爐特點(diǎn)：黑體的輻射腔體采用圓柱與同心圓V形曹設(shè)計(jì)，發(fā)射率高，精度高，控溫穩(wěn)定性好，先進(jìn)的AI控溫系統(tǒng)，同時(shí)具備多段修正功能，靶面溫度均勻，通用波長：8-14μm，升溫速率高，使用操作方便體積小重量輕，便于攜帶，適合用于實(shí)驗(yàn)室的校準(zhǔn)，也可用于現(xiàn)場的校準(zhǔn)工作。高溫黑體爐的工作波段為640-660，通常我們默認(rèn)腔式黑體爐的發(fā)射率為1.0.其實(shí)黑體爐無論做的在高精度，即使是球型腔體的黑體爐也無法滿足1.0的發(fā)射率，通常我們認(rèn)定發(fā)射率大于等于0.995的情況下，計(jì)量校準(zhǔn)可也按1.0亮度溫度校準(zhǔn)。黑體爐能用多少年？使用年限有沒有？</p><div

style="text-indent:25px">面源黑體爐使用溫度是多少？上海校準(zhǔn)黑體爐</p><p> <br /> </p> <p> 輻射溫度計(jì)是怎么校準(zhǔn)黑體輻射源的？輻射溫度計(jì)的光路一般有兩種形式，即變焦距和定焦距。輻射溫度計(jì)的靶標(biāo)為測溫儀光路是變焦距，并聚焦到黑體腔底。從光路圖可看出，通過黑體腔口的面積比到腔底的大，對于等溫黑體，只要腔口充滿視場，測量的溫度就準(zhǔn)確。沒有必要將鏡頭聚焦到腔底。如果鏡頭聚焦到黑體腔底，當(dāng)黑體腔和黑體的前沿段都較長時(shí)，為了滿足測溫的要求，這勢必要增加管式黑體的內(nèi)徑和腔口直徑，否則，腔口的尺寸就不能充滿測溫儀的視場，測溫就不準(zhǔn)確。
