400~2300nm光學可調諧濾波器
LLTF產品 Tunable Filter是款非反射率的亞納米級資源帶寬使用可調節為節為諧光學薄膜儀器濾波器。值得一看一提的是,這里是因為使用的有的體光柵水平,這一款可調節為節為諧光學薄膜儀器濾波用兼具令人驚訝的60%的非偏振穿透率,這里是FTS, Fabry-Perot, 聲光報警(AOTF),液晶拼接屏(LCTF)等做法所沒辦法企及的。光波長調諧根據線上系統設定,節約了如何修正激光切割機的光路引發的諸多不便。不但,主要是因為TNF產品超窄資源帶寬使用Notch Filter中的filter是由全鋼化玻璃產品制做,全部和傳統化的Notch Filter較,它兼具更多的損壞閾值法及的工作平均壽命。400~2300nm光學可調諧濾波器
