説明
製品説明
高精度マシンビジョン用電子式フォーカス対応リキッドテレセントリックレンズ
VT-TLL-23シリーズは、精密マシンビジョン、計測、および自動検査向けに設計された2/3インチCマウントリキッドテレセントリックレンズです。リキッドレンズ技術を採用することで、テレセントリック撮像性能を全焦点範囲にわたって維持しながら、高速な電子式フォーカシングと広い被写界深度を実現します。
倍率は0.4Xから4.0Xまで用意されており、VT-TLL-23シリーズはMTF >0.3 @100 lp/mmの高い光学解像度を提供し、精密計測および欠陥検査において優れた画像のシャープネスを確保します。反射面や厳しい検査アプリケーション向けに、同軸照明オプションバージョンも利用可能です。
機械的な再フォーカシングが必要な従来のテレセントリックレンズとは異なり、リキッドレンズ設計により、倍率、テレセントリック性、または画像品質を損なうことなく、迅速かつ再現性のある作業距離の調整が可能になります。
