Device for inserting optical and mechanical components into a sleeve

The invention relates to a device for inserting optical and mechanical components into mounting sleeves. The components are introduced upward from below into the mounting sleeve through a lead-through opening having movable locking elements. Although the locking elements allow the insertion of the components, they prevent the locking elements from leaving the mounting sleeve. The mounting sleeve is thus successively filled with insert parts. This type of insertion to a large extent counteracts the generation of dirt particles, in particular between the insert parts, and is outstandingly suitable for automation.
