Abstract
An optical unit that includes a lens and a frame that is configured to support the lens; wherein the lens has a coefficient of thermal expansion (CTE) of a first value; wherein the frame has a CTE of a second value; wherein the first value differs from the second value; and wherein at least one of the lens and the frame comprises a flexible interface for compensating for differences between thermal expansions of the lens and of the frame.

An optical unit that comprises a lens, a flexible interface and a frame that is configured to support the lens;
- wherein the lens has a coefficient of thermal expansion (CTE) of a first value;
- wherein the frame has a CTE of a second value;
- wherein the first value differs from the second value;
- wherein the lens and the frame are mechanically coupled to the flexible interface;
- and wherein the flexible interface is configured to compensate for differences between thermal expansions of the lens and of the frame.
A method for operating an optical device, the method comprises:
- supporting a lens by a frame;
- wherein the lens has a coefficient of thermal expansion (CTE) of a first value;
- wherein the frame has a CTE of a second value;
- wherein the first value differs from the second value;
- and compensating, by a flexible interface, for differences between thermal expansions of a lens and a frame.
