Description commune pour les Produits de la même Famille

Disponibles avec ou sans traitement antireflets à large bande
Idéales pour applications à large bande
Tailles de 5 mm de diamètre à carrés de 50 mm disponibles
Fenêtres en Silice Fondue UV λ/4 ou λ/10 aussi disponibles

Les Fenêtres 1λ en Silice Fondue UV TECHSPEC^® sont fabriquées avec précision en utilisant de la silice fondue synthétique. En plus d’une forte transmission, la silice fondue synthétique de ces fenêtres optiques fournit des propriétés thermiques plus élevées, une pureté exceptionnelle et une excellente durabilité environnementale pour toutes applications exigeantes. Les fenêtres sont idéales pour les applications à large bande sensibles aux coûts et sont disponibles sans traitement ou avec des traitements antireflets à large bande. Les Fenêtres 1λ en Silice Fondue UV TECHSPEC^®ont des tailles allant de 5 mm à 100 mm de diamètre. Des fenêtres λ/4 ou λ/10 UV en silice fondue sont également disponibles.

Remarque : Les nouveaux ajouts à cette famille de produits peuvent être précisés avec une spécification de distorsion du front d'onde transmis (TWD) au lieu d'une planéité de surface. Pour plus d'informations sur la différence entre ces deux spécifications, consultez notre note d'application Comprendre les fenêtres optiques.
