Abstract

L'invention concerne un module de lentille (10). Le module de lentille (10) comprend un barillet de lentille (100), une lentille et une bague de pression (300). Le barillet de lentille (100) comprend une paroi supérieure (110) ayant une ouverture (111) et une paroi de cylindre (120) se courbant et s'étendant à partir des bords de la paroi supérieure (110). La paroi supérieure (110) et la paroi de cylindre (120) sont reliées et jointes pour former une cavité. La lentille et la bague de pression (300) sont logées à l'intérieur de la cavité. De plus, la bague de pression (300) comprend une surface externe (310) en butée contre la paroi de cylindre (120). La paroi de cylindre (120) comprend une surface de butée (1211) en butée contre la surface externe (310). Le module de lentille (10) est également pourvu d'une rainure de réception de colle (101). La rainure de réception de colle (101) est formée par dépression sur au moins l'une de la surface externe (310) et de la surface de butée (1211). De plus, la bague de pression (300) est également pourvue d'un trou d'injection de colle (350) en communication avec la rainure de réception de colle (101). Pendant l'assemblage, une colle est injectée dans la rainure de réception de colle (101) à partir du trou d'injection de colle (350) pour relier la bague de pression (300) au barillet d'objectif (100), ce qui permet de fixer la lentille à l'intérieur du barillet de lentille (100) ; de plus, la colle en excès dans la rainure de réception de colle (101) est reçue à l'intérieur du trou d'injection de colle (350), empêchant ainsi la colle de déborder sur une partie optique de la lentille et d'affecter l'imagerie du module de lentille (10).
