DSC-E2UW MTF Inspection

產品特點Features
支援對角FOV 215˚量測,實現超廣角鏡頭檢測。Support FOV 215˚ (diagonal) measurement to achieve ultra-wide angle inspection requirements.
●MTF與Distortion修正補償二合一設計 ,節省校正程序及Reticle購買費用。
MTF Test and Distortion correction chart are both designed in a one reticle that simplified calibration process and more cost-effective.
 ●入光瞳高度可程式控制設定,提高料盤共用性及降低Collimator Camera調整機率。The attitude of entrance pupil is program controllable for raising the common multiusability of tray and decrease the chances of Collimator Cameras adjustment
 ●9~17 image regions組合供客戶選購及方便擴充升級。Combination of 9~25 image regions provides customers to purchase upgrades and expansion easily.
 ●結構強化讓機台在一般工廠環境中即可使用,不需要另外加裝防震設施。  Enhanced structural design allows machine operating in general factory environment without other vibration isolator.
