DSC-E2VF
MTF Inspection

 
DESCRIPTION
DSC-E2VF是以鏡頭MTF檢測為應用之產品,以涵概高倍(30x)變焦鏡頭為優先規劃考量、能擴大支援
手機、NB、監控、AR、VR、3D Sensing等鏡頭的檢測。 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。
 
產品特點Features
• 支援對角FOV 1.8˚~ 150˚量測,實現望遠及廣角鏡頭檢測。

• 除定焦鏡頭外,仍可搭配馬達驅動器實現變焦鏡頭W/M/T等三段以上變焦測試,可支援市面上30x Zoom產品。

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

• 含Wide、Middle、Tele等共10~22 image regions組合供客戶選購及方便擴充升級。

• 可固定變焦鏡頭調焦位置以Reticle作MTF掃描或固定Reticle後焦位置以鏡頭本身調焦掃描MTF或採上述兩者來回掃描、上述Wide ~Tele測試過程軟體會自動對心。
