Description commune pour les Produits de la même Famille

Versions traitées antireflets UV-VIS et UV disponibles
Distorsion du front d'onde transmis λ/10
Dimensions allant de 5 à 150 mm de diamètre
Fenêtres en Silice Fondue 1λ ou λ/4 également disponibles

Nos Fenêtres λ/10 en Silice Fondue UV TECHSPEC^® se caractérisent par un parallélisme et une qualité de surface indice laser. Par ailleurs, ces fenêtres limiteront la distorsion du front d'onde transmis à λ/10. Les caractéristiques de transmission supérieures, les excellentes propriétés thermiques et les spécifications de fabrication haute tolérance font de ces fenêtres un excellent choix pour les applications plus exigeantes. Les Fenêtres λ/10 en Silice Fondue UV TECHSPEC sont disponibles dans des tailles allant de 5 à 150 mm de diamètre. Ces fenêtres sont offertes sans traitement ou avec des traitements anti-reflets optimisés pour le spectre UV ou visible.
