Title (EN) APPARATUS AND METHOD FOR PRECISELY EXPOSING RADIATION SENSITIVE MATERIALS
(FR) APPAREIL ET PROCEDE PERMETTANT D'EXPOSER AVEC PRECISION DES MATERIAUX SENSIBLES AUX RADIATIONS
Abstract:
(EN) Radiant energy is directed from a source (14, 16) to an illumination plane (28) where the light receiving ends of groups (36) of optic fibers are arranged in coplanar striations (100), after which the radiant energy passes through the groups of optic fibers into individual exposure columns (40) and on to an exposure plane (42) where a radiation sensitive sample is exposed in individual areas to different, readily adjustable levels of illuminance from each of the groups of optic fibers.
(FR) L'énergie radiante provenant d'une source (14, 16) est dirigée sur un plan d'éclairement (28) où les extrémités de groupes (36) de fibres optiques recevant la lumière sont disposées de manière à former des stries coplanaires (100). L'énergie radiante traverse ensuite les groupes de fibres optiques, atteint des colonnes d'exposition individuelles (40) et continue jusqu'à un plan d'exposition (42) où chacun des groupes de fibres optiques expose des zones individuelles d'un échantillon sensible aux radiations à différents niveaux d'éclairement aisément réglables.
