Optical Substrates made of High Quality Glass

Substrates made of various special glasses

Optical substrates are often used as base glasses for optical coatings and precision optics. But also many scientific applications require glass substrates. Below please find a list with links to our standard materials:


Optical glass substrate


Please select a glass substrate:

BK7 substrates

Quartz glass substrates and quartz microscopy slides

Selected float glass substrates

BOROFLOAT® substrates

MEMpax® substrates

B270 Superwite substrates

1737F substrates

EAGLE2000 substrates

7059 substrates

D 263T substrates

AF 32 eco substrates

AS87 eco substrates

Borosilicate glass substrates

Infrared blocking substrates

Partially transmitting substrates

ITO-coated substrates

Substrate made of ULE™

Substrate made of ZERODUR®

Multilayer broadband antireflection coated substrates

Wafer substrates made of specialty glass


In many cases only one side of a substrate must have a high surface quality or flatness because a substrate usually is not used in transmission. However, if required our glass substrates can of course be double side polished (see "Optical Windows"). They can be customized for special surface quality or flatness requirements. Also custom coatings can be done per coating batch. We manufacture high quality optical substrates of nearly any suitable glass material available on the market.
