What is special about best laser torch?
Laser lamps, including gun and laser source. In this cylinder, the first focusing indoor and outdoor lenses are installed to reconstruct the homogeneous lens, the second focusing lens and the focusing lens. The design of the laser light source is to place the first focusing lens inside, provide a central lens at the end of the cylinder and attach the focusing lens to the lamp. This practical new design is intended to provide a uniform laser lamp with a large radiation range controlled by the radiation range. Laser is a special light source, Laser has many properties: first of all, laser is monochromatic or monochromatic. Some lasers can simultaneously produce lasers of different frequencies, But they are isolated and used separately. Second, laser is a coherent light. Characteristic of coherent light is that all its light waves are synchronous and the whole beam looks like a column. Third, the laser is highly concentrated, which means The researchers develop and use lasers of different wavelengths and frequencies, of which 400-1100 nm can be used for visual mapping of camouflage materials.

The best laser lanterns are used in police stations. It is especially suitable for the display of sweat in the palm. If the palm is printed on paper, the sweat of the palm remains on the paper. The best new laser lamps use several lenses to align, homogenise and reinforce the laser so that the last 20 cm lens has more than 1 cm diameter. A uniform lens is created, from one strip to an elliptical laser beam, The elliptical laser is circular and the circular laser point is amplified after focusing. In the area of 20 cm the diameter of the spot has changed by at least ten cm.The frequency range of the Laser pointer generated by the laser light source 2 is 400 ~ lloo nm, preferably the laser frequency is 445 nm or 450 nm; The cylinder I is successively provided with a first focusing lens 11, a shaping homogenizing lens group 12, a second focusing lens 13 and a focusing lens 14 from the inside to the outside, the laser light source 2 is arranged on the inner side of the first focusing lens 11, the end of the cylinder I is provided with a lamp cap 15 for focusing, and the focusing lens 14 is fixed on the lamp cap 15, wherein the first focusing lens 11 The second focusing lens 13 and the focusing lens 14 are convex lenses. The shaping homogenizing lens group 12 is composed of two homogenizing lenses 121 or a single lens arranged in parallel. Preferably, the second focusing lens 13 is an aspherical convex lens for focusing and further shaping the elliptical laser emitted by the shaping homogenizing lens group 12 into a laser with a circular spot.
