二向色濾光片(分色濾光片)用于需要隔離可見光譜的某些區(qū)域的各種應(yīng)用中。一些較常見的應(yīng)用是用于彩色放大器和復(fù)印機(jī)作為光平衡濾光器。它們?cè)谌魏慰赡苄枰獙⑷肷淠芰糠殖蓛蓚€(gè)或多個(gè)光束的應(yīng)用中也非常有用。以下光譜曲線以垂直入射方式顯示,但是對(duì)于許多應(yīng)用,例如組合顏色,可能希望以45°入射角以反射模式使用它們。
在這些過(guò)濾器中使用的所有涂層材料都產(chǎn)生堅(jiān)硬,耐用的介電薄膜,其沒(méi)有隨著使用年限和使用而降低的跡象。與使用時(shí)會(huì)褪色的有機(jī)染料或明膠類型不同,這些過(guò)濾器非常穩(wěn)定,不會(huì)隨著時(shí)間的推移而損失任何效率。這些過(guò)濾器也可以成套使用。過(guò)濾器也可以安裝在螺紋環(huán)中。
可根據(jù)要求提供定制尺寸,基材和光譜特性。
