Thermal despace compensation systems and methods

摘要

Techniques are disclosed for systems and methods to provide thermal despace compensation for optics assemblies, such as devices including one or more lenses and/or optical devices. A thermal despace compensation system may include one or more interfaces substantially situated between optical devices that expand and contract with changing temperature according to their coefficients of thermal expansion (CTEs). Each interface may be implemented with one or more shapes and/or interfaces adapted to provide a compensation despace to compensate for thermal expansion and contraction and/or reduce optical defects caused by changes in temperature of the various optical devices.

主权项

1. An optics assembly comprising:
a lens with a first coefficient of thermal expansion (CTE) and comprising a first interface; an optical device, substantially aligned with the lens along an optical axis of the optics assembly, with a second CTE and comprising a second interface; and at least one spacer arranged between the lens and the optical device and comprising a third interface that mates with and slides on adapted to mate with and slide relative to the first interface of the lens and a fourth interface that mates with and slides on adapted to mate with and slide relative to the second interface of the optical device, such that the at least one spacer is configured to slide relative to the lens and the optical device to provide, at least in part, a compensation despace to reduce one or more optical defects caused by changes in a temperature of the optics assembly.
