Double-auto-collimation optical system checking and regulating tube

Abstract

The invention discloses a double-auto-collimation optical system checking and regulating tube which relates to the technical field of measuring devices which are characterized by adopting an optical method. The tube comprises a shell, wherein two auto-collimation optical systems are arranged in the shell; a first auto-collimation optical system and a second auto-collimation optical system respectively irradiate light which is emitted from a light source onto a measured reflective mirror through optical devices; and an included angle which is formed by two light rays emitted by the first auto-collimation optical system and the second auto-collimation optical system is an acute angle. The checking and regulating tube adopts a light splitting principle and two groups of light splitting prisms; antireflection films are formed on incident and emergent surfaces through vacuum laser so as to make up the light energy loss which is caused by light splitting; a light splitting film is coated on a gluing layer, the thickness of the film is controlled so as to enable the light splitting ratio to reach 1:1; one light path provides high-precision auto-collimation to a target, so that the target is enabled to be clear and stable, and a problem of cross reticle superposition verification is solved; and the other light path provides a reading micrometer function so as to solve a zero position error verification problem.

Problems solved by technology

At present, all measurement methods and methods are verified by multi-collimator technology. This technology cannot completely cover equipment and parameters, and requires repeated erection and repeated leveling. The repeatability, reliability and consistency cannot be guaranteed. The measurement equipment is very It is huge, expensive, and has very strict environmental requirements. It can only be built in a laboratory in a special environment, and cannot meet the measurement requirements of the aiming equipment.

[0003] The design of conventional inspection and adjustment tubes must meet one condition: the focal length of the inspection and adjustment tube is more than 2 to 3 times the focal length of the tested collimator. The miniaturization and reliability design of the tube have brought great problems, which cannot meet the needs of the implementation of measurement guarantee; in addition, ordinary inspection and adjustment tubes do not have the function of micrometer measurement, and cannot realize the verification of "reticle overlap". It needs to be equipped with additional equipment such as T3000A or T5100A. This equipment is as high as hundreds of thousands, and the verification cost is extremely high

The inspection and adjustment tube designed with a single optical path cannot provide quantitative angle measurement and reading functions, cannot realize the verification of the zero position error of the azimuth and zero calibration light pipes, and cannot cover the verification of the pitch deviation in the case of one leveling and one erection

[0004] In the traditional aiming equipment verification device, the aiming target group adopts a distributed installation method, that is, multiple collimators are installed on the same bracket through their respective fixing parts, which may easily cause changes in the technical parameters and relative positions of the aiming target group. Moreover, the requirements for the operating environment temperature are very strict, which cannot meet the accompanying measurement guarantee work.
