Due to their excellent infrared properties, large-size formability, and low cost, mid-infrared transparent glass become the key window materials for many important military systems. It′s still a great challenge to fabricate the IR-transparent glass with high-properties and large size. With the great development of infrared technology and electro-optical countermining technique, the infrared windows with the capacity of radar latent and electro-magnetic shielding (EMS) are essentially required. In this paper, the research progress to face the above challenge is demonstrated and reviewed, especially which are done in our group. The prospect of mid-infrared glasses toward advanced applications is expected.
