DSC-E3VF
鏡頭檢測儀 Lens MTF Tester
以鏡頭MTF檢測為應用之產品。
涵蓋高倍(30x)變焦鏡頭為優先規劃考量為配合變焦鏡頭的馬達驅動因素，所以採單顆橫臥檢測方式作業。


應用產品
30X Zoom (變焦) 鏡頭。


特點
✔ 30x變焦鏡頭檢測。
✔ W/M/T等三段以上變焦測試。
✔ 支援對角 FOV 1.5˚~ 70˚量測。
✔ 模擬AA製程，可優化平衡 Wide 與 Tele 像面傾斜。


選配及升級
✔ 升級：含Wide、Middle、Tele等共10~22 image regions組合。

設備規格

Normally Average Test Time
(w/o load & unload)		 Including Wide, Middle and Tele mode: ~40sec
Note. The actual time depends on lens sample motor driving speed
MTF Repeatability
(excluding load & unload)
Reticle scanning at a certain Zoom Position
Delta MTF : (≤ 180lp/mm)
On axis ≤ 1.5 ; off axis ≤ 2.5
Note. It is hard to evaluate the machine when using lens to do MTF scanning because the major fluctuation factor is the sample lens AF movement stability
Maximum Measuring Frequency 300lp/mm
Limited FBL > -3.0mm
Limited Image Circle ≦16mm  ( >16mm customized)
Wavelength Photopic or NIR
