Description
Description du produit
Objectif télécentrique liquide avec mise au point électronique pour la vision par machine de haute précision
La série VT-TLL-23 est un objectif télécentrique liquide au montage C 2/3" conçu pour la vision par machine de précision, la métrologie et l'inspection automatisée. En intégrant la technologie d'objectif liquide, elle permet une mise au point électronique rapide et une profondeur de champ étendue tout en maintenant des performances d'imagerie télécentrique sur toute la plage de mise au point.
Disponible en grossissements de 0,4X à 4,0X, la série VT-TLL-23 offre une résolution optique élevée avec un MTF >de 0,3 @100 lp/mm, garantissant une netteté d'image excellente pour la mesure de précision et l'inspection des défauts. Une version à illumination coaxiale optionnelle est disponible pour les surfaces réfléchissantes et les applications d'inspection exigeantes.
Contrairement aux objectifs télécentriques conventionnels qui nécessitent une remise au point mécanique, la conception à objectif liquide permet un ajustement rapide et répétable de la distance de travail sans compromettre le grossissement, la télécentricité ou la qualité de l'image.
