DSC-E2DV
MTF Inspection

 
DESCRIPTION
DSC-E2DV為DSC-E2系列產品是以鏡頭MTF檢測為應用之產品,特點是物距可透由程式設定改變從30cm至無窮遠及2M虛像等可連續變化,適用於手機、NB、監控、AR、VR等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
• DSC-E2DV程式可控物距切換可滿足不同物距量測的需求。

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

• 9~17 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。

• 針對近紅外線850nm或950nm不需更換校正Collimator Lens。
