Abstract

The invention discloses an ultralow-temperature collimator device in a vacuum environment. The ultralow-temperature collimator device comprises: a supporting cylinder device; a first reflecting mirror which is arranged at one end of the supporting cylinder device; a second reflecting mirror which is arranged at the other end of the supporting cylinder device, wherein the reflecting surface of the first reflecting mirror is opposite to the reflecting surface of the second reflecting mirror; and a cooling device which is arranged on the outer side of the supporting cylinder device in a surrounding mode. The ultralow-temperature collimator device in the vacuum environment can have the same change rate in the ultralow-temperature environment, and the overall precision of equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of photoelectric measuring instruments, in particular to an ultra-low temperature collimator device in a vacuum environment. Background technique [0002] Collimator is a commonly used measuring instrument, mainly an optical instrument used to generate parallel light beams. It is an important tool for installing and adjusting optical instruments, and is also an important part of optical measuring instruments. The micro-eye lens, or microscope system, can measure the focal length, discrimination rate and imaging quality of the lens group. [0003] For the general collimator in the ordinary laboratory environment, the ambient temperature difference is small, which basically has no effect on the uniformity of the collimated light emitted by the collimator. Uncontrollable deformation occurs at ultra-low temperature, which causes the focal plane to drift, and the parallelism of the outgoing light decreases, ther...
