Ultra-flat Quartz Coated Glass Substrates

Spectroscopy Equipment, Substrates and Fabrication

High-quality quartz coated glass substrates

Ultra-flat glass substrates available to purchase in three dimensions

These ultra-flat glass substrates are coated with a 20 nm layer of synthetic quartz.

For many applications standard glass is simply not good enough due to either surface roughness or wettability. These synthetic quartz covered substrates are useful for a variety of activities such as absorption/PL measurements, OFET fabrication and surface profilometry where superior wettability and/or flatness are required.

The substrates come with small squares of ITO (Indium Tin Oxide) in the corners to help identify the SiO₂ coated side.
