冷(leng)鏡(jing)是熱鏡(jing)的反面(mian)，它反射(she)可(ke)見(jian)光(guang)並透射紅外光(guang)。它們的塗(tu)層都(dou)是**面(mian)的，並且像熱鏡(jing)壹樣(yang)，也沈積在低膨(peng)脹(zhang)率的材料上(shang)，例(li)如(ru)硼(peng)矽酸鹽(yan)玻璃。這(zhe)些反射(she)鏡(jing)通(tong)常在隨(sui)機偏(pian)振(zhen)光(guang)中(zhong)以(yi)45°入射(she)角(jiao)使用。

熱鏡

熱(re)鏡按其名稱說(shuo)明(ming)執行：它們反射(she)熱(re)量(liang)並透射可見光(guang)。所(suo)有塗(tu)層均被歸(gui)類為堅硬的**表面(mian)電介(jie)質(zhi)，並且將達到(dao)或(huo)超(chao)過規定(ding)的濕(shi)度和磨損(sun)規範(fan)。為防止高溫(wen)應用導(dao)致(zhi)開裂或(huo)開裂，所(suo)有塗(tu)層均沈積在低膨(peng)脹(zhang)材(cai)料（例(li)如(ru)硼(peng)矽酸鹽(yan)玻璃）上(shang)。
