A lithographic apparatus is disclosed that includes an imprint template and a radiation source configured to cure photosensitive material, the radiation source including a laser or a light emitting diode. The process includes an interrelationship among at least four bath vessels, each of which has a molten metal bath. The first plurality of bearing mount actuators is configured to adjust the radial position of the first bearing assembly. A spoiler is pivotally mounted at the rear of the shell, and is interposed between the rear of the leg portion and the rear of the inshoe. These materials have increased photographic speed especially in the infrared region of the electromagnetic spectrum. An active ventilation unit is attached with a body wall which includes a portal housing defining a portal, a portal cover and a portal cover actuator for selectively adjusting the portal cover to thereby increase or decrease the unobstructed size of the opening of the portal.
