Our gold (Au) material is 99.999% pure and is deposited onto Borosilicate glass coverslips (Gold Seal®) using electron beam evaporation. We use a thin layer of chromium (99.99%) as an adhesion promoter for all our coatings. All substrates are pre-cleaned using an ion source for quality assurance.
At Substrata/Angstrom Engineering, we take pride in offering high-quality substrates at affordable prices.
