OPTICAL STRUCTURE FOR AEROSPACE ENGINEERING

摘要

PURPOSE: An aerospace optical structure is provided to comprise a separable lens barrel and connect a spider supporting sub-reflector to a connecting member, thereby minimizing geometrical or dimensional deformation of the spider. CONSTITUTION: An aerospace optical structure comprises a lens barrel(10), a main reflector(20), a sub-reflector(30), and a spider(40). The main reflector is installed in the inside of the lens barrel and arranges an image in focus by collecting light. The sub-reflector magnifies the image arranged on the focus. The spider fixes the sub-reflector in the inside of the lens barrel. The lens barrel is comprised of a combination of a plurality of lens barrel members(10a). Each lens barrel member is combined with insertion through a hinge joint(60). One side of the spider is connected to the sub-reflector. The other side of the spider is connected to the hinge joint.
