Abstract
This installation includes: a light source; means for storing film photoresist for exposure and exposed photoresist; a film carrier for positioning said film photoresist at an exposure plane; a projection lens capable of projecting the digital images at the exposure plane; a liquid crystal matrix where the various digital images to be exposed are displayed; a retractable mirror oriented at 45° to an optical axis of the projection lens; and an image analysis device positioned symmetrically to said exposure plane with regard to the plane containing said mirror when the latter is in place on the optical axis. When said mirror is positioned on the optical axis, the image analysis device is suitable for receiving the image transmitted by the liquid crystal matrix issuing from the projection lens. The signals thereby detected are processed using an associated software, for setting the characteristics of the optical members of the installation.
