Abstract
A zero-clearance, axially displaceable aligning mount system for optical components includes an unthreaded mount receptacle having a transverse orifice and includes an aligning mount carrying lens elements or lens combinations. A cured plastic casting compound forms a thread substitute in the region of the transverse orifice and beyond it. Coating of this region with an antiadhesion agent, prior to application of the casting compound in pasty form, prevents the molded threads from sticking.
Claims17
An axially displaceable aligning mount system for at least one optical component, comprising:
- an aligning mount configured to receive the at least one optical component, the aligning mount including cylindrical end regions having a guidance diameter and including a transport thread in a central region of the aligning mount, a diameter of the transport thread being no greater than the guidance diameter;
- and
- a mount receptacle including:
- a cylindrical orifice having the guidance diameter and being unthreaded;
- at least one transverse opening in a central region of the mount receptacle;
- a one-piece threaded segment at least partially disposed in a region of the transverse opening facing the transport thread and in a region of the transport thread.
A method for manufacturing an axially displaceable aligning mount system for at least one optical component, comprising:
- preassembling an aligning mount having the at least one optical component disposed therein and a transport thread;
- applying an antiadhesion coating to the transport thread;
- disposing the preassembled aligning mount in cylindrical opening of a mount receptacle, the mount receptacle having at least one transverse opening opposite the transport thread;
- introducing a plastic casting compound into the transverse opening and against the coated transport thread;
- and
- forming a one-piece threaded segment by allowing the plastic casting compound to cure.
