Membrane Window Products

Norcada provides high-quality ultra-clean silicon nitride membrane windows for the X-ray microscopy and TEM analysis research communities.

• The silicon nitride membrane is robust and low stress (~250MPa), and is ideally suited for a wide range of microscopy and spectroscopy work such as TEM, X-ray, IR and UV.
  
  
• Standard silicon nitride membrane windows are fabricated on 200µm thick square silicon support frames (2.65mm, 5mm, 7.5mm, and 10mm).
  
  
• Standard nitride window sizes include 0.25mm, 0.5mm, 1.0mm, 1.5mm, 3.0mm, and 5.0mm.  Nitride thickness available range from 50nm to 500nm.
   
  
• All nitride windows are cleaned vigorously to remove any organic residue, and carefully inspected and packaged to make sure particle contamination is minimal.
  
  
• Development work is also currently underway for Nitrogen-Free Membrane Windows, to further enhance our product offering for the TEM microscopy and X-ray spectroscopy research communities.
