Abstract

The utility model discloses a device for generating parallel light paths in a vertical direction, which comprises a laser source, a holophote and an oil immersion lens. The laser source corresponds to the holophote, and the oil immersion lens is correspondingly arranged below the holophote. Incident laser emitted by the laser source in a horizontal direction is reflected via the holophote and vertically irradiates to the surface of the oil immersion lens, and vertical reflecting laser is returned. On a long light path, the incident laser and the reflected laser are assuredly coincident completely. By the aid of the device, light paths which are severely vertical or parallel to the ground can be obtained. In a laboratory, the device can be used for measuring parallelism of an experimental platform. In field experiments, the device can ensure verticality of high buildings relative to the ground.

Description

The generation device of vertical direction parallel light path
Technical field
The utility model relates to a kind of generation device of vertical direction parallel light path, belongs to the device that utilizes light path to measure levelness and verticality.
Background technology
Prior art: the guaranteeing of the horizontal accuracy of the catoptron of horizontal surface realized by the catoptron level is installed on the experiment porch, and the levelness of experiment porch is generally calibrated by using the mercury level to discuss.
The defective that exists: even large-area experiment porch can guarantee certain levelness, but the levelness that is fixed on the small size catoptron on the experiment porch can only be finely tuned by mechanical hook-up and be realized, be difficult to the high levelness of maintenance, promptly enable to finely tune the levelness that guarantees that mirror surface is certain by mechanical hook-up, but the fine setting needization regular hour.
The utility model content
The utility model purpose is to carry at the defective that prior art exists, and utilizes the surface reflection of oily mirror, produces strict vertical parallel light path, utilizes three beams vertical parallel light can find telescopical focus.
The utility model adopts following technical scheme for achieving the above object:
The generation device of the utility model vertical direction parallel light path is characterized in that comprising LASER Light Source, completely reflecting mirror and oily mirror, the wherein corresponding setting of LASER Light Source with completely reflecting mirror, and oily mirror correspondence is arranged at the catoptron below.
Described completely reflecting mirror and oily mirror are at 45 mutually.
The utility model utilizes this light path can obtain and the strict vertical or strict parallel light path in the face of land.In the laboratory, can be used for measuring the depth of parallelism of large tracts of land experiment porch.Experiment can be guaranteed the verticality on the high-lager building and the face of land in the open air.
Description of drawings
Fig. 1: the utility model structure drawing of device.
Fig. 2: the utility model light path produces process flow diagram.
Embodiment
As shown in Figure 1, the device of the generation of vertical direction parallel light path comprises LASER Light Source 1, completely reflecting mirror 2 and oily mirror 3, wherein LASER Light Source 1 and completely reflecting mirror 2 corresponding settings, and oily mirror 3 correspondences are arranged at catoptron 2 belows.
Described completely reflecting mirror 2 and oily mirror 3 are at 45 mutually.
As shown in Figure 2, horizontal direction laser is incided on the 45 degree mirror surfaces, the angle of accurately regulating minute surface incides on the oily mirror minute surface laser vertical, lens paper moves around on long light path, incident laser and the laser beam by oily mirror surface reflection are overlapped fully, the light path of guaranteeing downward incident like this is strict vertical with the face of land, and it is parallel with face of land strictness also to guarantee to incide the preceding light path of 45 degree catoptrons simultaneously.
