Abstract
The utility model provides a green light reticle laser demarcation device light source. A beam splitter prism is arranged on a laser, and is formed by butting a parallelogram and an isosceles right triangle; cylindrical mirrors are arranged on an adjusting head; and a cylindrical mirror a and a cylindrical mirror b are arranged vertical to each other. On the basis of a green light point light source, the beam splitter prism is adopted for directly partitioning a point light source into two points, and reticles which are vertical to each other are directly formed through two cylindrical mirrors which are vertical to each other. Due to the adoption of the laser demarcation device light source, the blank of the domestic industry is filled up, the production efficiencies and productivities of domestic measuring instruments are increased greatly, and a solid foundation is laid for the popularization of a laser precision measuring instrument in China.
Description
Technical field
The utility model relates to the accurate laser measurement instrument.
Background technology
Laser level is a common measurement instruments in work such as building, decoration, building maintenance, article installation, and the level LASER Light Source is its core component, and its precision directly influences accuracy of instrument.In these measuring processes, often use laser point light source, horizontal line, perpendicular line light source again.Green glow is because its line matter is beautiful, and the environment for use brightness limit is little and be widely used in surveying instrument.At present, because there is not green (light) laser, the green-light source of being done is that the infrared laser by the 808nm wavelength comes through crystal double frequency entirely, and green glow cross curve light source industry is blank especially.
Summary of the invention
The purpose of the utility model provides a kind of new construction green glow cross curve laser level light source, can satisfy the requirement to the light source precision, has improved product stability.
The technical scheme that realizes the utility model purpose is: a kind of new construction green glow cross curve laser level light source; Amici prism is arranged on the laser instrument; Amici prism adopts parallelogram and isosceles right triangle butt joint to form; Cylindrical mirror is arranged to be regulated on the head, and wherein cylindrical mirror comprises cylindrical mirror a and cylindrical mirror b and cylindrical mirror a and cylindrical mirror b vertical setting each other.
The utility model forms on the green glow pointolite basis through crystal double frequency at the 808nm infrared laser, forms two points through Amici prism, directly forms orthogonal cross curve through two orthogonal cylindrical mirrors again.It is blank to have filled up domestic industry, has improved domestic surveying instrument production efficiency and productive capacity greatly, popularizes at home for the accurate laser measurement instrument and has laid solid foundation.
Major technique and performance index
The design of selecting for use of optical system and mechanical realization is satisfied the requirement of different clients to physical dimension on the one hand, reaches the purpose of exquisite appearance, on the other hand, satisfies the requirement to the light source precision.Only the quality of guaranteed standard point and precision could be passed through the precision that Amici prism guarantees two points, and then realize the precision of line source, reach precision index, realize the functional effect of green glow cross curve level light source, have improved product stability greatly.

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, green glow cross curve laser level light source, its assembling sequence are that Amici prism 2 places on the laser instrument 1, and cylindrical mirror 3 places regulates on 4 cylindrical mirror 3a and the orthogonal setting of cylindrical mirror 3b.
As shown in Figure 2, laser instrument 1 is that the 808nm laser instrument sends the green glow pointolite after through crystal double frequency.As shown in Figure 3, Amici prism 2 is arranged on the laser instrument 1, adopts the butt joint of parallelogram and isosceles right triangle to form, and its surface forms semi-transparent semi-reflecting effect through special coating film treatment.Thereby realize that a standard point through the Amici prism 2 a part of transmissions in back, part reflection, forms two standard points.As shown in Figure 4, cylindrical mirror 3 is arranged at regulates on 4 cylindrical mirror 3a and the mutual vertical setting of cylindrical mirror 3b.As shown in Figure 5, regulate 4 be used for regulating cylindrical mirror 3 the position, the light positive that makes two standard point light sources forms orthogonal cross curve green-light source well through orthogonal cylindrical mirror 3a and cylindrical mirror 3b.
