Embodiment Construction

[0013] The surface of the anti-counterfeiting label described in the present invention is a concave or vaporized layer, and the graphic resolution is 0.2 mm. It consists of the mask transmission part with characters and patterns and the remaining total reflection part to form the co of the output mirror 1 of the resonant cavity. 2 The laser anti-counterfeiting marking machine is vaporized, the co 2 The resonant cavity of the laser anti-counterfeiting marking machine is composed of the total reflection part of the above-mentioned output mirror 1 and another reflector 2. The above-mentioned output mirror 1 is made of gallium arsenide or zinc selenide crystal material, and its mask is partially plated with a transmission medium Gallium arsenide or zinc selenide film, the total reflection part is coated with total reflection film gold, and the transmittance range of the output mirror is 20-80%.

Abstract

A laser false proof mark with picture output features as the mark surface being a hollow or evaporation layer with picture resolution ratio of 0.2 mm. It has been formed by evaporating CO2 laser false proof mark shooter of cavity resonator output mirror formed by mask film transparent part with letter and picture characteristics and the rest of all reflection part. The abovesaid CO2 laser false proof mark shooter has specialized as that it is formed by all reflection part of optical output mirror being structure by mask film transparent part with letter and picture characteristics and the rest of all reflection part and an other reflection mirror. It can be used in stead of the laser holograpy trademark which is not good in effect for false proof.

Description

technical field [0001] The present invention relates to anti-counterfeiting marks and special equipment, in particular to a graphic output laser anti-counterfeiting mark and a co 2 Laser anti-counterfeiting marking machine. Background technique [0002] Traditional laser anti-counterfeiting marks are generally holographic plane patterns with low resolution, and special tools are required for identification, which is difficult for ordinary people to identify, and its anti-counterfeiting effect is not ideal, and it is easy to be imitated. Contents of the invention [0003] The object of the present invention is to provide a laser anti-counterfeiting mark with high graphic resolution and concave-convex graphic output, which is easy to identify and has good anti-counterfeiting effect. [0004] In order to achieve the above invention, the present invention adopts the following technical solutions: a graphic output laser anti-counterfeiting mark, which is characterized in that ...
