Optical Substrates made of High-Quality Glass

Substrates made of various special glasses

Optical substrates are base glasses for optical coatings and precision optics for light and laser applications in science, research, and industry. Below, please find a list with links to our standard materials suitable for the production of substrates:

Wafer substrates made of specialty glass


In many applications, only one side of a substrate material must have high surface quality and flatness because a substrate is usually not used for transmission. However, our glass substrates can also be double-side polished (see "Optical Windows"). We can customize them for unique surface quality or flatness requirements. Furthermore, we can apply custom coatings in a custom coating run. We manufacture high-quality optical substrates and also optics with laser quality from nearly any suitable glass material available on the market.
