以 1mm 厚度實現低 GDD
低損耗寬頻 IBS 抗反射鍍膜
專為 370nm 至 2200nm 波長所設計
鍍膜 GDD 為 ±30fs²

TECHSPEC® 超快薄型窗鏡設計採用 1mm 厚度，以實現低群組延時色散 (GDD)，是超快雷射應用的理想選擇。這類薄型窗鏡兩面均採用最佳的離子束濺鍍 (IBS) 寬頻抗反射鍍膜，於 370nm 至 2.2μm 波長範圍內提供低反射率。IBS 鍍膜製程也讓這類窗鏡具備更低的吸收損耗及散射，優於傳統鍍膜的抗反射窗鏡。TECHSPEC 超快薄型窗鏡也可用於需要高效能、體積精巧光學窗鏡的一般光學應用。我們也供應無鍍膜薄型窗鏡基材（紫外線熔融石英或紅外線級熔融石英），以提供客製鍍膜的彈性，因應各種應用需求；請與我們聯絡瞭解詳情。

紅外線等級熔融石英與紫外線等級熔融石英的差異，在於前者能夠減少 OH- 離子量，在整個近紅外線光譜產生更高的穿透效果，並在紫外線光譜減少穿透。
