Abstract
The invention discloses a cylindrical lens which comprises a lens body, wherein an arc surface is arranged on one end face of the lens; the length a of the lens and the width b of the lens are both 10mm; the radius R of the arc surface of the lens is 10-14mm. The cylindrical lens has the advantages that the structure is simple, emitted laser beams can be changed from point shapes into thin strip shapes when the cylindrical lens is installed in a laser nozzle emitting the laser beams on a sensor, the radiation surface of the laser beams for air is increased, and detection precision of an environment tester is improved.
Description
Technical field
The present invention relates to sensor field, relate in particular to a kind of for the post mirror in the sensor.
Background technology
Along with the continuous progress of science and technology, people improve constantly the technical level of environment measuring, particularly the detection of air pollution degree.In order to detect the content of particle in the air, people carry out sample detecting by the environmental testing instrument to air, by the sensor that is arranged in the environmental testing instrument airborne granule content are analyzed.Its method is, air feeds in the sensor by the valve on the sensor, discharged by the gas outlet on the sensor, and the laser beam on this moment sensor passed the air of circulation again, and the reflection case by laser beam detects airborne granule content.
At present, be point-like after the beam of sensor inner laser goes out, therefore, it is smaller to wear the face of penetrating air, and test accuracy is lower, influences testing result.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of laser beam that can make to become face by point, the post mirror of increase laser-beam irradiated face.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of post mirror, comprise lens body, and described lens one end face is provided with arc surface.
Further, described length of lens a and width b are 10mm.
Again further, described lens arc surface radius R is 10～14mm.
Compared with prior art, usefulness of the present invention is: this post mirror is simple in structure, it is installed in the laser mouth of launching laser beam on the sensor and the laser beam that penetrates can be become fine strip shape by point-like, increase laser beam to the shadow surface of air, improved the accuracy of detection of environmental testing instrument.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of post mirror of the present invention structural representation;
Fig. 2 is a kind of post mirror side structure synoptic diagram;
Fig. 3 is a kind of post mirror structure synoptic diagram.
Among the figure: 1, lens; 2, arc surface.
Embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
Fig. 1, Fig. 2 and a kind of post mirror shown in Figure 3 comprise lens 1 body, and described lens 1 one end faces are provided with arc surface 2; Described lens 1 length a and width b are 10mm, and arc surface 2 radius Rs of described lens 1 are 10～14mm.
Its concrete use-pattern is as follows, the post mirror is installed on the environment measuring instrument sensor in the laser mouth, and the laser mouth is mapped to laser beam on the plane of post mirror, because post mirror other end is circular-arc, therefore, can make the laser beam of point-like become fine strip shape, the laser beam of fine strip shape is passed the detection gas in the sensor, has increased the contact area of laser beam and air, if contain solid particle in the air, laser beam will be blocked, and can not pass through reflection, thereby realize the detection of particle in the air.
This post mirror is simple in structure, and it is installed in the laser mouth of launching laser beam on the sensor and the laser beam that penetrates can be become fine strip shape by point-like, increases laser beam to the shadow surface of air, has improved the accuracy of detection of environmental testing instrument.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
