Aspheric lens with solid shell and liquid inner core

A method for manufacturing an optical lens, comprising:

• processing a sheet of optical material to form a plurality of aspheric-shaped shells;
• assembling the plurality of aspheric-shaped shells with an optical plate to produce a lens assembly;
• processing the lens assembly to produce a lens housing that includes a single one of the aspheric-shaped shells and a portion of the optical plate;
• and
• processing the lens housing by providing a viscous fluid within a cavity between the single one of the aspheric-shaped shells and the portion of the optical plate.

A system for maintaining pressure within an optical element, comprising:

• an optical lens comprising:
• an aspheric-shaped shell formed of an optical material;
• an optical plate connected to the aspheric-shaped shell;
• and
• a viscous fluid fluidically sealed in a cavity between the aspheric-shaped shell and the optical plate;
• and
• a capsule attached to the optical lens, the capsule includes the viscous fluid,
• wherein the capsule is configured to maintain a constant pressure within the cavity between the aspheric-shaped shell and the optical plate over a range of operating temperatures of the optical lens.

A method for manufacturing an optical lens, comprising:

• processing a sheet of optical material to form a plurality of aspheric-shaped shells;
• processing the plurality of aspheric-shaped shells to produce individual ones of the aspheric-shaped shells;
• processing the individual ones of the aspheric-shaped shells by providing a viscous fluid into the individual ones of the aspheric-shaped shells;
• and
• providing, for each of the individual ones of the aspheric-shaped shells, a spherical lens,
• wherein the viscous fluid is within a cavity between the aspheric-shaped shell and the spherical lens.
