Beschreibung Produktfamilie

  • Dicke 0,2 mm
  • Präzises N-BK7-Substrat
  • Extrem leicht

TECHSPEC® Ultradünne N-BK7-Fenster sind unsere dünnsten Fenster und haben nur 1/10 der Dicke unserer standardmäßigen N-BK7-Fenster. Durch die extrem geringe Dicke eignen sie sich ideal für Anwendungen mit kritischen Gewichts- und Platzvorgaben. Durch ihre engen Toleranzen weisen sie zudem eine minimale Strahlverzerrung und Streuung auf. Sie werden unbeschichtet oder mit einer Antireflexionsbeschichtung aus MgF2 geliefert. Wenn Sie kundenspezifische Größen oder besondere Beschichtungen benötigen, wenden Sie sich bitte an unser Vertriebsbüro.

Hinweis: Die ultradünnen N-BK7-Fenster sind extrem empfindlich, bitte mit Vorsicht behandeln.
