Abstract
A method of optically centering a lens, in which each lens is placed between two clamping pipes, after which the clamping pipes are moved towards each other. A pressurized fluid flows between the lens and bearing surfaces on the pipe ends to eliminate friction which would prevent accurate centering. The lens may then be cemented to the lower clamping pipe as a lens mount. A number of mounting rims may be similary stacked in sequence on the mount to form a lens assembly.
