Präzise λ/4-Fenster aus N-BK7

×
  • Runde und rechteckige Fenster von 2 mm bis 200 mm
  • 8 breitbandige Antireflexionsbeschichtungen erhältlich
  • Weltgrößte Auswahl an Standardfenstern aus N-BK7
  • Auch als ultradünne N-BK7-Fenster lieferbar

Die TECHSPEC® präzisen λ/4-Fenster aus N-BK7 eignen sich ideal für Industrielaser und Laser mit niedriger Leistung. Durch die engen Toleranzen ergibt sich eine minimale Streuung und Verzerrung. Die breitbandigen AR-Beschichtungen erweitern den Einsatzbereich dieser Präzisionsfenster auf das sichtbare Spektrum und NIR-Spektrum. Die TECHSPEC® präzisen λ/4-Fenster aus N-BK7 werden rund oder rechteckig mit Größen zwischen 2 mm und 200 mm angeboten.

Bitte beachten Sie: Neue Produkte, die zu dieser Produktfamilie hinzugefügt werden, können mit der transmittierten Wellenfrontverzerrung (TWD) und nicht mehr mit der Oberflächenebenheit spezifiziert sein. Weitere Informationen über den Unterschied zwischen den beiden Spezifikationen finden Sie unter Grundlagen optischer Fenster.
