Ｃ Ｃ Ｄ 用于天文领域已经有近２０ａ （ 年） 的历史， 随着 Ｃ Ｃ Ｄ 技术的发展， 作为重要参数之一的量子效率也得到极大提高， 已经有许多效率在蓝端超过９０ ％ 的芯片应用于天文观测。本文介绍了提高 Ｃ Ｃ Ｄ 蓝端量子效率的多种方法， 包括电极减薄、 Ｌｕｍｏｇｅｎ 镀膜、 Ｃ Ｃ Ｄ 减薄、紫外预照、电子预注入和增透膜等技术等等。可以看到， 采用 Ｃ Ｃ Ｄ 减薄、电荷注入和选择合适的增透膜可以使量子效率接近１００ ％
C C D has been used in the field of astronomy for nearly 20 years. With the development of C D technology, the quantum efficiency as one of the important parameters has also been greatly improved. There have been many efficiencies of more than 90% The chip used in astronomical observations. This article describes several ways to increase quantum efficiency at the C C D blue end, including electrode thinning, Lumogen coating, C D thinning, UV pre-irradiation, electron pre-injection and AR coatings. As can be seen, using C C D thinning, charge injection, and the selection of a suitable AR coating can bring about a quantum efficiency close to 100%
