FAQ
What is a quartz glass plate?
A quartz glass plate is a flat fused silica optical component featuring high purity, excellent light transmission and superior heat resistance.
What is the difference between quartz glass and ordinary glass?
Quartz glass delivers far higher temperature tolerance, lower thermal expansion and much better UV transmittance than conventional glass.
What is the maximum operating temperature?
Continuous working up to 1100°C, short instant exposure up to 1300°C.
Can quartz glass plates withstand thermal shock?
Yes. Its ultra-low thermal expansion coefficient gives excellent thermal shock resistance.
