Abstract

The invention provides a detection device and method, wherein the detection device is simple in structure and accurately detects parallelism of two split beams at the two sides of a prism of a detected lens. A main body of the detection device comprises an autocollimator, an angular instrument, a plane detection platform, a three-dimensional autocollimator adjusting base and a lens base; the detection device is combined with the detection method, and the absolute value, in the horizontal direction and the vertical direction, of the parallelism of the split beams of the optical lens can be detected. Non-contact type measurement is adopted for the detection device and method, the device is convenient to put up and dismount, easy to operate, good in detection repeatability, high in precision and low in cost, repeated accuracy can reach 2', and main components, namely the autocollimator and the angular instrument, of the device can be dismounted in any time and used for other detection purposes.

Description

technical field [0001] The invention belongs to the technical field of lens optical axis parallelism detection, and in particular relates to an optical lens sub-beam parallelism detection device and a detection method thereof. Background technique [0002] Night vision devices are widely used in the military field due to their superior night observation capabilities. However, in recent years, night vision devices have also been used by many law enforcement officers, police, judicial, hunting, firefighting, forests, etc., and are also widely used in various monitoring fields, and are also used in high-end cars. The binocular monocular type is currently a more popular optical path structure. The optical path of the objective lens is separated by a right-angle prism to separate two lines of light in the same straight line and opposite directions. The performance of the objective lens after assembly, especially the horizontal and vertical directions of the two lines of light Th...
