Product Description

Product Description

ColdQuanta’s high-quality glass cells offer a new level of optical access to in-vacuum experiments, while our high clearance option also provides maximum mechanical access within vacuum. Assembled with an optical contacting process, the cells provide high-quality AR coatings while maintaining very high optical flatness in the cell walls, enabling minimal optical distortion through the cell. The cells are connected to the flange through an anodic bond to a silicon transfer, and have no epoxy or frits, giving them excellent outgassing properties.
