材料简介

      Introduction

黑色石英玻璃材料同时具备 ,   高纯度、高光学吸收率、高发射率 以及

低热导率，

因此可提高工艺环境的热均匀性，屏蔽过程中向外辐射热量，

从而增加热管理的自由度。此外，较其他黑色陶瓷其加工性能更优。

Ultra-low expansion quartz glass with a diameter of more than 1meter, It has a near-zero thermal expansion coefficient in the room temperature range, and the zero expansion point temperature range is controllable. As a mirror of precision optical system, laser resonant cavity and other components, it is used in space-based space telescopes, optical components for semiconductor lithography equipment, atomic clocks and other fields.
