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.
- Custom optical wafer manufacturing and polishing
- Diameters up to 450mm
- Thickness down to 0.1mm
- High-volume capabilities
Sydor Optics also offers a variety of glass wafer services including wafer thinning back-grinding, ultrasonic cleaning & spin rinse drying in a cleanroom environment, cleanroom packaging and CNC machining for mechanical alterations such as flats, notches & bevels. Additional customizations can be made utilizing laser cutting & marking capabilities for adding features such as serial numbers, custom shapes and patterns or laser dicing. All Sydor Optics glass wafers go through a meticulous metrology and inspection process to ensure that your products are in spec and of the highest quality possible.
Available Material Types
Based upon customer demand, Sydor Optics offers Glass Wafers made from the following substrate materials. Of course, if you don’t see a material you need, please contact a Sales Engineer, who will gladly discuss additional options that may be available.
- Crystal
- Magnesium Fluoride (MgF2) Wafers
Popular Materials - Display Glass Wafers
- Fused Quartz WafersFused Quartz is made using high quality, natural quartz powders with several fusion methods. Quartz material is stronger than glass, can be used at high temperatures (<1050°C) and has a high average transmission of over 80% from 260nm to 2500nm. The various qualities of fused quartz allow for use in a wide range of applications from semiconductor applications to lower precision window applications in hostile environments.
