Laser cross light source

The utility model discloses a debugging structure of a laser cross-hair light source, belonging to the technical field of optical equipment. The debugging structure of the laser reticle light source includes an outer cylinder 1, a horizontal cylindrical mirror and a vertical cylindrical mirror are arranged in the head of the outer cylinder 1, and the head of the outer cylinder 1 is provided with a 45 ° double saw seam debugging structure; the upper end surface of the head of the outer cylinder 1 is respectively provided with a vertical laser line accuracy adjustment hole 2 and a horizontal laser line accuracy adjustment hole 3, the vertical laser line accuracy adjustment hole 2 and the horizontal laser line accuracy adjustment hole 3 are respectively provided with 2, which are symmetrically distributed along the diagonal line, the two sides of the head of the outer cylinder 1 are respectively provided with vertical laser line and horizontal laser line clip angle accuracy adjustment hole 4. The structure of the utility model is simple, the debugging method is convenient and efficient, the precision is high, and the laser line is long.

Compared with the general light, the laser crosshair light source has four characteristics:

(1) High brightness

Due to the strong emission capacity and high concentration of energy of the laser cross-hair light source, the brightness is very high, it is hundreds of millions of times higher than the ordinary light source, tens of billions of times higher than the brightness of the sun's surface. Brightness is an important indicator to measure the quality of a light source. If a medium-intensity laser beam is converged, a high temperature of thousands to tens of thousands of degrees can be generated at the focus.

(2) good direction

After the laser crosshair light source is emitted, the divergence angle is very small. The laser emits 20 kilometers, and the spot diameter is only 20-30 centimeters. When the laser hits the moon 380000 kilometers, the spot diameter is less than 2 kilometers.

(3) good monochromaticity

The color of light is determined by the different wavelengths of light, and different colors are reflected by the different wavelengths of light acting on human vision. The wavelength of the laser is basically the same, the spectral line width is very narrow, the color is very pure, and the monochromativity is very good. Because of this characteristic, laser is widely used in communication technology.

(4) good coherence

Coherence is the commonality of all waves, but due to the different qualities of various light waves, their coherence is also high and low. Ordinary light is spontaneous radiation light, does not produce interference phenomenon. Laser is different from ordinary light source, it is stimulated radiation light, with strong coherence, so called coherent light.
