Description

  • Tailles circulaires et carrées de 2 mm à 200 mm
  • 8 options de traitements antireflets à large bande disponibles
  • La plus grande sélection au monde de fenêtres standard N-BK7
  • Également disponibles : Fenêtres Ultra-Minces N-BK7

Les Fenêtres de Précision λ/4 en N-BK7 TECHSPEC® conviennent parfaitement aux applications laser industrielles et de faible puissance. Leur concept à tolérances étroites produit une distorsion et une dispersion du rayon minimes. Les options de traitement à larges bandes élargissent la gamme de ces fenêtres de précision grâce au spectre visible et infrarouge proche. Les Fenêtres de Précision λ/4 en N-BK7 TECHSPEC® sont proposées dans des tailles circulaires et carrées allant de 2 mm à 200 mm. 

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.
