Abstract
A package includes a) a tray that transmits less than about 0.5% of selective actinic radiation and having a top surface and at least two recesses in the top surface, each recess adapted to hold a light-curable material, b) a rigid plate covering the recesses that transmits less than about 0.5% of actinic radiation and transmits at least part of the visible light spectrum, such that the plate is sufficiently transparent to permit viewing inside the recesses, c) an arrangement for maintaining the plate in contact with the top surface of the tray to permit the plate to slide relative to the tray and filter incident radiation entering the recess, and d) a light-curable material in at least one of the recesses, that is curable upon removal of the rigid plate and exposure to sufficient actinic radiation.
