MSE Supplies offers low stress perforated silicon nitride membrane windows. A layer of silicon nitride is deposited onto the silicon and go through patterning and etching process (MEMS process) in order to manufacture desired shape of silicon nitride membrane window. Perforated silicon nitride membrane window offers excellent optical clarity, high mechanical strength, resistance to high temperature (up to 1000°C) and corrosion, which make it suitable for harsh environments. It has holes that perform better in terms of optical properties, which makes it suitable for material characterization applications. It is often used for microscopy (TEM, SEM, AFM/SPM, etc.), spectroscopy, optical sensing, and many other applications.
