Produktbeschreibung
Flüssigkeits-Telezentrisches Objektiv mit elektronischem Fokus für hochpräzise Machine Vision
Die VT-TLL-23-Serie ist ein 2/3"-C-Mount-Flüssigkeits-Telezentrisches-Objektiv, das für präzise Machine Vision, Messtechnik und automatisierte Inspektion entwickelt wurde. Durch die Integration der Flüssigkeitslinsentechnologie ermöglicht es einen schnellen elektronischen Fokus und eine erweiterte Schärfentiefe, während die telezentrische Bildqualität über den gesamten Fokusbereich hinweg aufrechterhalten wird.
Verfügbar in Vergrößerungen von 0,4X bis 4,0X, liefert die VT-TLL-23-Serie eine hohe optische Auflösung mit MTF >0,3 @100 lp/mm, was eine hervorragende Bildschärfe für präzise Messung und Defektinspektion gewährleistet. Eine optionale Version mit koaxialer Beleuchtung ist für reflektierende Oberflächen und anspruchsvolle Inspektionsanwendungen erhältlich.
Im Gegensatz zu herkömmlichen Telezentrischen Objektiven, die eine mechanische Nachjustierung erfordern, ermöglicht das Flüssigkeitslinsen-Design eine schnelle, wiederholbare Anpassung der Arbeitsentfernung, ohne die Vergrößerung, Telezentrität oder Bildqualität zu beeinträchtigen.
Hauptmerkmale
✔ Flüssigkeitslinsentechnologie
Elektronischer Fokus ermöglicht eine schnelle, präzise und wartungsfreie Fokusanpassung.
✔ Erweiterte Schärfentiefe
Erhält scharfe Abbildung über einen größeren Fokusbereich, was die Inspektionseffizienz verbessert.
✔ 2/3"-C-Mount-Kompatibilität
Optimiert für Industriekameras mit Bildsensoren bis zu 2/3".
✔ Vergrößerung von 0,4X bis 4,0X
Unterstützt eine breite Palette von Machine-Vision- und Präzisionsmessanwendungen.
✔ Hohe optische Auflösung
MTF >0,3 @100 lp/mm für genaue Kantenerkennung und Abbildung feiner Details.
✔ Optionale Version mit koaxialer Beleuchtung
Ideal für reflektierende, polierte und metallische Oberflächen.
