Problems solved by technology

Only industrial lasers cannot be used for lighting demonstrations, because their beams are too thin and cannot be used for long distances due to the divergence angle.
In addition, because it needs to scan various patterns in the demonstration field, the existing light demonstration beam expander system cannot meet the needs of these occasions

Embodiment Construction

[0012] Further details will be given below in conjunction with the preferred embodiments shown in the accompanying drawings.

[0013] Such as Figure 1-Figure 3 As shown, the embodiment of the present invention provides a laser beam expander system, which is applied to lighting demonstration occasions such as advertisements or stage demonstrations. The beam expander system includes a laser 1, a lens and a vibrating mirror. The lens includes a first lens L1 and a second lens L2, and the two lenses are located on the same optical axis; the first lens L1 is a biconcave lens, and its curved surface faces away from the light. The direction of incidence, and the first lens L1 is a beam expander, and its beam expansion factor is 8 times; the second lens L2 is a meniscus lens, and its curved surface faces the direction of light incidence; the first lens L1 and the second lens The interval between L2 is d2, and its value is: 60.0mm±5%. The diameter of the beam emitted by the laser 1 ...

Abstract

The invention provides a laser beam expanding lens system, comprising a laser, lenses and a oscillating lens, wherein, the two lenses are located at the same optical axis; the first lens is a double concave lens, and the curved surface backs the incident direction of the light; the second lens is a meniscus-type lens, and the curved surface faces the incident direction of the light; the first lens is the beam expanding lens; through arranging the meniscus-type lens and the double-concave lens, and through adjusting the distance between the lens as the precision adjustment light beam, the emitted light beam is lead to display light beam with clear light, in order to meet different needs. The laser beam expanding lens system is used as advertisement demonstration, stage demonstration and other occasions, therefore, the invention is widely used, the scanning of the laser beam expanding lens system is flexible, and patterns of various colors and designs can be rapidly weaved through the oscillating lens.

Description

technical field [0001] The invention relates to an optical lens, in particular to a laser beam expander system for lighting demonstration. Background technique [0002] With the application of laser as lighting demonstration, in recent years, the fastest growing stage lighting demonstration system has been widely used in advertising demonstrations, stage demonstrations and other occasions. Because the demonstration site is small, it does not require a large beam of light and a long-range distance effect like a city demonstration. Therefore, the demonstration system must be small and flexible in scanning. Only industrial lasers cannot be used for lighting demonstrations, because their beams are too thin and cannot be shot far due to the divergence angle. In addition, because it needs to scan various patterns in the demonstration field, the existing light demonstration beam expander system cannot meet the needs of these occasions. Contents of the invention [0003] The tec...
