Low expansion optical materials, as their name implies, are known for an impressively low coefficient of thermal expansion and are very resistant to high-temperature thermal shock. Typically, low expansion materials have a near zero coefficient of thermal expansion. Ceramic glass substrates are generally engineered to retain their mechanical and optical properties – especially reflected wavefront – even during extreme temperature changes.
The material has very high mechanical strength, high chemical durability/resistance, and superior machinability characteristics. These materials can be available in sizes up to 8 meters in diameter with the bulk of the mirror substrates ranging in the in the 1 – 2 meter range.
