UMA / 產品介紹 / 鏡頭MTF檢測設備


DSC-E2 Serie
鏡頭檢測儀 Lens MTF Tester
支援對角FOV 179˚量測,實現廣角鏡頭檢測。Support FOV 179˚ (diagonal) measurement to achieve 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 much cost-effective.
●9~25 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.
●結構強化設計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 any additional vibration isolator.
●程式可控物距切換可滿足不同物距量測的需求Program controlled motorized collimator can meet different objective distances measurement requirements.
