Product Family Description

  • Ultra-Thin 0.20mm Thickness
  • Precision N-BK7 Substrate
  • Extremely Lightweight

TECHSPEC® Ultra-Thin N-BK7 Windows are our thinnest windows available and are at least 1/10 the thickness of our traditional N-BK7 windows. Their extremely thin designs make them ideal for both weight and size sensitive applications. Additionally, their high tolerance design yields minimal beam distortion and scatter. They are available uncoated or with a MgF2 anti-reflection coating. For custom sizes or coating options, please contact our Sales Department.

Note: The Ultra-Thin N-BK7 Windows are very fragile. Handle these windows with care.
