Abstract
The utility model provides a laser illumination night vision telescopic range finder. The laser illumination night vision telescopic range finder comprises a laser receiving module for receiving reflected light of an illumination object, wherein the laser receiving module comprises an illumination object lens group, a receiving lens and a laser receiving tube; the receiving lens is arranged on the emitting light path side of the illuminating object lens group and is used for receiving laser; the laser receiving tube is arranged on the emitting light path of the receiving lens; a semi-transparent and semi-reflection mirror, a beam expanding lens group and a laser tube for providing illumination are sequentially arranged along an optical axis on the emitting light path side of the illumination object lens group; and the receiving lens is arranged on a reflection light path of the semi-transparent and semi-reflection mirror. According to the laser illumination night vision telescopic range finder, the laser tube for providing the illumination, the beam expanding lens group and the reflection mirror are only additionally arranged in the laser receiving module of a traditional laser telescopic range finder, so that the laser illumination night vision telescopic range finder is simple in structure, easy for realization and low in cost; more importantly, night illumination is realized and the acceleration of the construction progress is facilitated; and particularly, due to the adoption of night illumination, infrared imaging can be avoided, further the cost is reduced and the popularization and application are facilitated.
Description
Technical field
The utility model relates to a kind of laser range finder, specifically is that a kind of laser with illumination functions stadimeter of looking in the distance is the laser lighting night vision stadimeter of looking in the distance.
Background technology
The existing domestic and international tradition stadimeter of looking in the distance does not have night vision function, can not realize using night, has limited the operation period, influence construction speed, and uses infrared imaging mostly, and the cost height is difficult to popularize.
The utility model content
The purpose of the utility model is that a kind of laser with illumination functions stadimeter of looking in the distance is the laser lighting night vision stadimeter of looking in the distance; Do not have night vision function to overcome the stadimeter of looking in the distance at present, can not realize using night, limited the operation period; Influence construction speed; And using infrared imaging mostly, cost is high, the problem that is difficult to popularize.
For reaching above-mentioned purpose; The utility model provides a kind of laser lighting night vision stadimeter of looking in the distance; Comprise and be used for receiving the catoptrical laser pick-off module of illumination thing; This laser pick-off module comprises the illumination objective lens group, be arranged on this illumination objective lens group the emergent light trackside reception laser receiver lens and be arranged on the laser pick-off pipe on this receiver lens emitting light path, it is characterized in that: along being disposed with semi-transparent semi-reflecting lens, expanded beam lens group on the optical axis of the emergent light trackside of said illumination objective lens group and being used to provide the laser tube of illumination; Said receiver lens is arranged on the reflected light path of said semi-transparent semi-reflecting lens.
The utility model has the advantages that: just, existing laser increased laser tube, expanded beam lens group and the reflective mirror that illumination is provided in looking in the distance the laser pick-off module of stadimeter, and simple in structure, be easy to realize; With low cost; Priorly realized night illumination, helped the lifting of construction speed, especially had the night illumination just need be by infrared imaging; Reduced cost undoubtedly, be beneficial to and apply.

Description of reference numerals: 1, telephotolens; 20,21, the prism group; 3, graticule; 4, the eyepiece group; 5, diversing lens; 6, the emission laser tube; 7, the illumination objective lens group; 8, semi-transparent semi-reflecting lens; 9, expanded beam lens group; 10, laser tube; 11, receiver lens; 12, the laser pick-off pipe.
Embodiment
Traditional laser stadimeter of looking in the distance, its distance measurement function mainly is made up of Laser emission module and laser pick-off module, wherein; The Laser emission module, as shown in Figure 1, by telescopic ocular 1; Prism group 20,21, graticule 3, eyepiece group 4; Diversing lens 5, emission laser tube 6 constitutes, and main task is an emission laser radiation object; And the laser pick-off module is mainly by illumination objective lens group 7; Receiver lens 11 constitutes with laser pick-off pipe 12, and its main task receives through the irreflexive laser of object, this shows; Night vision illumination is not provided in the total system; Must influence laser and look in the distance operation period of stadimeter, influence construction speed, for this reason; Present embodiment improves the light path system of laser pick-off module; Specifically be along having set gradually reflective mirror 8, expanded beam lens group 90,91 on the optical axis of the emergent light trackside of illumination objective lens group 7 and be used to provide the laser tube 10 of illumination, simultaneously receiver lens 11 has been arranged on the reflected light path of reflective mirror 8, not influenced the reception of 12 pairs of reflector lasers of laser pick-off pipe.
The laser that present embodiment the provided stadimeter of looking in the distance has just increased laser tube, expanded beam lens group and the reflective mirror that illumination is provided in existing laser is looked in the distance the laser pick-off module of stadimeter, simple in structure; Be easy to realize, with low cost, priorly realized night illumination; Help the lifting of construction speed; Especially there has been the night illumination just need be, reduced cost undoubtedly, the laser that helping present embodiment is especially provided the applying of stadimeter of looking in the distance by infrared imaging.
To sum up, the laser that present embodiment provided is looked in the distance stadimeter owing to have a night illumination function, therefore is referred to as the laser lighting night vision stadimeter of looking in the distance.
