產品系列說明

雙高斯 (DG) 設計可降低畸變率至小於 0.3%
支援最大1.3吋傳感器
薄型靜態外殼專為機器整合設計
特別適用於高解析度相機

TECHSPEC® DG系列定焦鏡頭採用雙高斯設計，具備高效能、精巧外型與實惠價格，表現優於一般市售定焦鏡頭。其鏡頭具備齒輪機構設計,讓使用者可以搭配馬達進行電動調焦，成像解析度高於100 lp/mm，並採用標準C接口。針對大多數的應用，均可使用隨附於相機的¼-20接口來將相機與鏡頭組合架設於工作站。TECHSPEC® DG系列定焦鏡隨附對焦環、手動光圈及固定螺絲，以便於在機器視覺應用中執行薄型整合。DG系列鏡頭的一般應用包括機器視覺、裝配線整合、量測和影像分析。

注意： 建議使用工業用調整架來設置無震動工作站。
