Abstract:
1. An apparatus, comprising: a work area; an uncaging light source that directs uncaging light at the work area or a selected portion thereof, wherein optical power density of the uncaging light is substantially uniform over the entire work area; an optical meter that monitors the uncaging light; and, an exposure controller that controls optical energy density of the uncaging light to which the work area or the selected portion thereof is exposed, whereby the work area is exposed to a desired optical energy density selected by a user of the device, wherein the exposure controller controls the optical energy density of the uncaging light by controlling the optical power density of the uncaging light and/or an exposure time, which exposure time is an amount of time to which the work area or the selected portion thereof is exposed to the uncaging light, and wherein the exposure controller accepts a signal from the optical meter.
