The present invention relates to an anti-counterfeiting marker which consists of a glass block. The inside of the glass block is provided with an even number of laser damage points which are arranged on a plane or more than two planes. The glass block is mixed with metal. In the method of producing the anti-counterfeiting marker, a laser is used for producing an even number of laser damage points in the glass block; a vibrating mirror and an F-Theta lens are arranged between the laser and the glass block; the output interface of the vibrating mirror is connected with the output interface of the F-Theta lens; a carving path is preset in the computer according to the carved picture; the laser emits laser pulses onto the vibrating mirror; the laser focuses in the glass block and forms a fusing and exploding point after passing through the vibrating mirror and the F-Theta lens; the computer is used for controlling the rotation of the vibrating mirror so as to control the moving track of the laser; ultimately the glass block is treated through heat and color treatment. The anti-counterfeiting marker can engrave the trademark or identification mark in the glass block, and has excellent anti-counterfeiting effects.
Description
Technical field: [0001] The invention relates to the field of physics, in particular to laser processing technology, in particular to an anti-counterfeit marker and a manufacturing method thereof. Background technique: [0002] Anti-counterfeiting technology has penetrated into daily life. The existing anti-counterfeiting technologies include physical anti-counterfeiting, chemical anti-counterfeiting, biological anti-counterfeiting, etc. Physical anti-counterfeiting technology is the application of mechanical, light, heat, electricity, magnetism, sound and computer-aided identification in physics. The anti-counterfeiting technology established by the system, such as special printing graphics, watermarks, laser holographic images, optically variable films, super anti-counterfeiting marks, magnetic passwords, etc. Chemical anti-counterfeiting technology is to add substances that can cause chemical reactions under certain conditions in anti-counterfeiting marks. Such as photoch...
