Description
- Traitées AR pour offrir <0,5% de réflectivité par surface entre 350 - 700 nm
- Minimisent les aberrations sphériques et la coma
- Lentilles DCX en Silice Fondue UV disponibles
- D’autres options de traitement disponibles : Non Traitées, MgF2, VIS 0°, NIR I, NIR II, VIS-NIR et YAG-BBAR
Les Lentilles Biconvexes (DCX) avec Traitement VIS-EXT TECHSPEC®, également appelées lentilles double-convexes (DCX), ont deux faces positives et symétriques avec des rayons égaux des deux côtés. Ces lentilles sont généralement recommandées pour les applications d’imagerie finie avec un rapport conjugué (rapport entre la distance de l’objet et la distance de l’image) compris entre 0,2 et 5. Pour un rapport conjugué de 1, les aberrations telles que l’aberration sphérique, l’aberration chromatique, la coma et la distorsion sont minimisées ou annulées grâce à la conception symétrique de la lentille. Les Lentilles Biconvexes (DCX) avec Traitement VIS-EXT TECHSPEC sont disponibles dans une variété de substrats et d’options de traitement pour les spectres visible et NIR.
