黑體輻射概述：黑體輻射是指由理想放射物放射出來的輻射，在特定溫度及特定波長放射很大量之輻射。同時，黑體是可以吸收所有入射輻射的物體，不會反射任何輻射，但黑體未必是黑色的，例如太陽為氣體星球，可以認為射向太陽的電磁輻射很難被反射回來，所以認為太陽是一個黑體（黑體是不存在的）。理論上黑體會放射頻譜上所有波長之電磁波。維恩位移定律是描述黑體電磁輻射能流密度的峰值波長與自身溫度關系的定律。所以人工生產的黑體都是假定發(fā)射率為1.0（實際上到了，比較高為0.998±0.002）上海黑體爐黑體爐不準時如何校準的。</p><div

style="text-indent:25px">超高溫黑體爐能到多少度？上海黑體爐原理</p><p> 黑體的物理意義：是能全部吸收外部的輻射能量，同時能全部輻射出自身全部能量的物體。量化說明吸收率為1，發(fā)射率為1。這是理想黑體，理想黑體是一極限值。通常我們所說的黑體產品為人工黑體，人工黑體的發(fā)射率接近1，但不等于1。通常人工黑體發(fā)射率大于0.99，標準黑體作為標準輻射源，主要用于校準輻射溫度計、紅外溫度計和輻射溫度傳感探測器。我公司目前具有國際很先進的黑體技術，產品種類很全、溫度范圍廣，黑體種類齊全，黑體的工作溫度為-50～1600℃，能覆蓋大多數(shù)行業(yè)的紅外測溫。
