Glass Wafers

Aside from standard size glass wafers such as 100mm, 150mm, 200mm and 300mm, Sydor Optics can provide custom wafers with diameters up to 450mm and thin wafers with thicknesses down to 0.1mm.

Custom Glass Wafer Fabrication

Sydor Optics has decades of experience polishing precision glass wafers. Aside from standard size glass wafers such as 100mm, 150mm, 200mm and 300mm, Sydor Optics can provide custom wafers with diameters up to 450mm and thin wafers with thicknesses down to 0.1mm (± 0.003mm).

With the largest collection of double-sided grinding and polishing machines in North America, Sydor Optics has the flexibility to easily ramp up wafer manufacturing from prototype to high-volume production. Regardless of the size or scope of your project, our experienced engineers and technicians will guide you every step of the way.
