ColdQuanta’s high-quality glass cells offer a new level of optical access to in-vacuum experiments. 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.
This cell family is designed to be used with readily available microscope objectives, including the G Plan APO 20x and 50x ULWD objectives from Mitutoyo, which allow the user to access samples at 0.3 and 0.5 NA, respectively. The cell is fabricated to ensure excellent parallelism between the two large faces, making it possible to image or project light through two faces of the cell with almost no astigmatism. 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.
