TMC 730 SERIES Vacuum Compatible CleanTop
Several new proprietary design features, cleaning methods, and a vacuum pump-down procedure achieve a level of vacuum compatibility previously unattainable.
Though this new design does not require baking (and is incompatible with baking), engineers at University of Texas' Petawatt Laser have achieved 8 x 10-7 torr in a 7-foot diameter, 380 cubic foot chamber containing a 14-foot long CleanTop Optical Top.
Closely correlated with their vacuum compatibility is the fact that these tops only out-gas extremely small amounts ensuring they do not damage optics. The top for the Petawatt Laser application was demonstrated to cause less than a 0.1% loss in optical transmission of a test optic.
