Abstract

The invention is suitable for stage lighting demonstration and provides a laser beam expanding device. The laser beam expanding device comprises a first lens and a second lens which are positioned on the same optical axis; the first lens is a biconcave lens, and the second lens is a meniscus lens of which the convex side is bent towards the emergent direction of rays; and the distance d2 between the first lens and the second lens is more than or equal to 25mm and less than or equal to 35mm and the first lens is a beam expanding lens. The invention also provides the demonstration system. In the demonstration system, a first vibrating lens is arranged on the output optical path of the second lens, and a second vibrating lens is arranged on the reflection optical path of the first vibrating lens. The laser beams emitted by the laser beam expanding device are parallel to each other and are suitable for stage demonstration. The parallel light beams can be strafed randomly in the 180-dgree range in the spatial vertical direction after being reflected by the first vibrating lens. The parallel light beams can be strafed randomly in the 360-dgree range in the spatial horizontal direction after being reflected by the second vibrating lens, and patterns of various designs and colors can be quickly formed by using laser of different colors.

Description

technical field [0001] The invention belongs to an optical path adjustment device, in particular to a laser beam expander and a demonstration system. Background technique [0002] The laser color is bright and saturated, suitable for stage lighting demonstrations. However, the laser beam emitted by the laser is thinner and diverges due to the divergence angle. The stage lighting needs parallel light beams, so that the demonstration system can quickly compile patterns of various colors. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a laser beam expander that can expand the diameter of the laser beam to more than 4 times the original and emit in parallel. [0004] Another object of the embodiments of the present invention is to provide a flexible scanning demonstration system. [0005] The embodiment of the present invention is realized in this way. A laser beam expander includes: a first lens and a second lens, t...
