ABSTRACT:
A system and method for mounting the strip seal on the side of a pass-through positioning stage. The strip seal can effectively provide support to a cover of the stage and be magnetically coupled to the cover and base for an enhanced seal and added support. Accordingly, the tendency for the stage to sag and vibrate during operation is mitigated. Moreover, a side-mounted strip seal is exposed to a reduced amount of debris that accumulates on the top of a stag, and thus is less susceptible to contaminants entering the interior of the stage. As such, and in connection with a variety of other means for reducing contamination, the stage can operate for longer periods of time without wear and/or maintenance, etc.
