제목: Advances in Low Thermal Expansion Materials for Telescope Applications

초록

The Korea Institute of Photonics and Technology is at the forefront of optical research, particularly in the development of advanced optical materials. This presentation focuses on ceramic optical materials characterized by very low thermal expansion coefficients, which are crucial for large-diameter mirror applications in space telescopes. We will examine several materials, including ZERODUR, ULE, CLEARCERAM-Z, and SiC, which are commonly used in optical devices for space applications.

We will discuss the manufacturing processes and unique properties of these low-expansion materials, along with practical case studies showcasing the production of large telescope mirror materials. Furthermore, the presentation will provide an overview of the current technological advancements in low expansion materials, highlighting their significance in enhancing the performance of astronomical instruments
