Abstract
A lens cap for protecting a lens having an optical portion, the lens cap having a base with a spring membrane, and a sidewall arranged to surround the optical portion, so as to create a cavity between the base and the optical portion. The spring membrane arranged to be movable between a deformed position wherein the spring membrane is deformed toward the optical portion, and a rest position wherein the spring membrane extends away from the optical portion.
Claims19
A lens cap for protecting a lens having an optical portion, the lens cap comprising:
- a base with a spring membrane;
- and
- a sidewall extending from the base and dimensioned to fit around the lens, where the spring membrane is arranged to be movable between:
- a first position where the spring membrane is arranged to be concave and at a first distance from the optical portion, and
- a second position where the spring membrane is arranged to be convex and at a second distance from the optical portion, the second distance being greater than the first distance.
A lens having an optical portion at one end and a lens cap covering the optical portion, the lens cap comprising:
- a base with a spring membrane;
- and
- a sidewall extending from the base and dimensioned to fit around the lens, where the spring membrane is arranged to be bistable and movable between:
- a first position where the spring membrane is arranged to be concave and at a first distance from the optical portion, and
- a second position where the spring membrane is arranged to be convex and at a second distance from the optical portion, the second distance being greater than the first distance,
- wherein the second position of the spring membrane is arranged to face away from the optical portion.
