Abstract
A MEMS based alignment technology based on mounting an optical component on a released micromechanical lever configuration that uses multiple flexures rather than a single spring. The optical component may be a lens. The use of multiple flexures may reduce coupling between lens rotation and lens translation, and reduce effects of lever handle warping on lens position. The device can be optimized for various geometries.
Claims15
-11. (canceled)
A device for use in an optical assembly, comprising:
- a multi-part lever structure coupled to a substrate by a base, the multi-part lever structure including a first flexure coupled to the base, an elongate arm, and at least a second flexure and a first member coupling the elongate arm to the first flexure;
- and
- a lens coupled to the multi-part lever structure.
A structure for use in optically aligning two optical components, comprising:
- an elongate arm;
- a first flexure extending from the elongate arm in a first direction;
- a second flexure extending from the elongate arm in a second direction, the second direction being different than the first direction;
- a first member extending from the first flexure, with a mount for an optical component coupled to the first member;
- a second member extending from the second flexure;
- a third flexure, a third member, and a fourth flexure coupling the second member and the first member;
- and
- a fifth flexure coupling the second member to a base.
-30. (canceled)
A device for use in aligning optical components, comprising:
- a platform for receiving an optical component;
- means for flexibly coupling the platform to a base;
- an elongate arm coupled to the platform, the elongate arm terminating in a handle;
- and
- means for flexibly coupling the handle to other portions of the elongate arm.
