400~2300nm光學(xué)可調(diào)諧濾波器
LLTF系列 Tunable Filter是一款非色散的亞納米帶寬可調(diào)諧光學(xué)濾波器。值得一提的是，因?yàn)椴捎玫膿碛械捏w光柵技術(shù)，這款可調(diào)諧光學(xué)濾波器具有驚人的60%的非偏振透過(guò)率，這是FTS, Fabry-Perot, 聲光（AOTF），液晶（LCTF）等方法所無(wú)法企及的。波長(zhǎng)調(diào)諧通過(guò)電腦程序控制，省去了重新調(diào)整光路帶來(lái)的不便。此外，由于TNF系列超窄帶寬Notch Filter中的filter是由全玻璃材料制成，所以和傳統(tǒng)的Notch Filter比較，它具有更高的損傷閾值及工作壽命。
