冯·阿登纳为成本敏感型行业提供闪光灯式退火处理工艺

对于大面积基片,冯·阿登纳 开发了高效率低成本的闪光灯式退火处理解决方案,这种方案已经在最宽 3.8 米基片的建筑玻璃镀膜中得到证实。 (图 1)。  

对于小面积基片,例如半导体行业中使用的基片,闪光灯式退火处理工艺已经成功实现商业化。但是,对于宽度超过 1.5 米的基片而言,目前的闪光灯式退火处理解决方案成本太高,因为必须组合多个闪光灯阵列。复杂的设备组装会带来巨额的资本支出,而成本敏感型行业的公司基本无力承担。对于大面积基片,冯·阿登纳 提供适用于宽度不超过 3.8 米的基片的退火工艺。

The effort to build the LSST is a partnership between public and private organizations. Financial support for LSST comes from the National Science Foundation, the Department of Energy, and private funding raised by the LSST Corporation, a non-profit 501(c)3 corporation formed in 2003, with headquarters in Tucson, AZ. Contributions from private foundation gifts, grants to universities, and in-kind support from laboratories and other LSST Member Institutions were key to early construction and critical developments. 

With the help of the LSST, the scientists are aiming at mapping the Milky Way, other smaller objects (such as asteroids that might get close to the earth) in our solar system and changes in the night-time sky. Beyond that, they will look for dark matter and dark energy and want to observe short-time phenomena such as supernovae.

The Large Synoptic Survey Telescope is a mirror telescope with three mirrors: the primary mirror with a diameter of 8.4 meters, into which the 3.4 meter tertiary mirror is integrated, and the secondary mirror, which has a diameter of 5 meters. The site of observatory is located on the ridge of the Cerro Pachón mountain in northern Chile at an altitude of 2,682 meters. Due to the extremely dry climate of this region, the night-time sky is very clear. That is why there are already several observatories in northern Chile, two of which are also on the Cerro Pachón. The construction work on the LSST started in July 2014, the laying of the foundation stone was in April 2015. The first light, i.e., the first use of the telescope for testing purposes, is planned for 2019 and full science operations will begin when construction is completed in 2022.

The LSST will have a field of view of 3.5 degrees, which is considerably wider than those of other telescopes of a similar class (the sun and the moon have a diameter of 0.5 degrees when observed from the earth). That is what will enable the LSST to record the entire visible sky in only three nights in the first place. The images will be captured by the largest digital camera ever built. It has a focal plane with a diameter of 0.64 meters and a resolution of 3.2 billion pixels. The camera is expected to produce up to 30 terabytes of data per night.

Mirror Coatings for Maximum Reflectivity

冯·阿登纳 针对高生产率和大面积基片提供独特的闪光灯工艺,它具有以下优势: 

  • 通过最大程度缩短周期,提高生产率
  • 实现卓越的电子和光学性能
  • 借助冯·阿登纳灯阵概念,实现很高的均匀性
  • 通过不超过 3.8 米的灯阵长度,进行大区域 R2R & S2S 工艺
  • 面向成本敏感性行业的高效机器设计 

该技术也可应用于其他膜层系统。在实验室规模上,闪光灯式退火处理工艺显著改进了透明导电层的传输和导电性。
