光纖頭鍍膜端要求：
?高質(zhì)量的光纖拋光端面，粗糙度影響鍍膜質(zhì)量。眾周所知，膜層的反射率跟膜層厚度有直接關(guān)系。如 果鍍膜凹凸不平，導(dǎo)致膜層厚度不均勻，光透射或者反射率會(huì)受到明顯的影響。鍍膜端面的清潔度是 另外一個(gè)原因，因?yàn)椴煌该鞯奈镔|(zhì)容易吸收激光產(chǎn)生熱量，導(dǎo)致光線(xiàn)頭燃燒。
?光纖頭研磨沒(méi)有無(wú)膠水殘留，因?yàn)榇蠖鄶?shù)膠水都是有機(jī)物，容易燒光纖，光纖側(cè)面也必須有很高 的清潔度
?低熱吸收和高損壞閾值鍍膜，因?yàn)榧す饽芰亢艽?，密度很高，要確保膜層能承受如此大的能力密度
