鏡頭檢測儀 Lens MTF Tester


DESCRIPTION
DSC-E2TE同DSC-E2WE系列是以鏡頭MTF檢測為應用之產品,適用於長焦距或小視角鏡頭的大批量在線生產檢測。具有速度快、精度高、重現佳、價格合理等特點,並可與業界標準合致。
 
產品特點Features
• 支援FOV 4.5˚ ~ 35˚量測,實現小視角鏡頭檢測,其他規格仍可提供客製。

• MTF與Distortion修正補償二合一設計 ,節省校正程序及Reticle購買費用。

 • 5~25 image regions組合供客戶選購及方便擴充升級。

 • 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。

 • 可支援潛望式鏡頭,唯需加裝反射鏡治具且只能單顆測試。
