Laser engraving machine is a certain wavelength of the laser into the glass or crystal inside, make specific parts of the interior of the occurrence of fine bubbles burst form, which outlines the shape of a pre-processing technology, also refers to this process processing out of handicrafts.
Crystal laser engraving principle
These glass, crystal products with a computer-controlled laser engraving mechanism made of. In fact, most are not usually seen in a real crystal crafts, but man-made crystal. "Laser" is artificial crystal (also called "crystal glass") in "Carving" the most useful tool. Laser engraving technology, or three-dimensional pattern of "carving" inside the crystal glass.
The carving is an ancient art of carving are generally moment from the outside, from outside material carved out of a desired shape, and laser but can be like the Monkey King "into the hinterland" to display their hands. Carefully inspected, the glass around the crystal products totally not for "graver" out of the opening, on this point, the laser also clever than the Monkey King, the monkey to fall in the stomach when people should have slit the job too! Laser engraving is actually very simple principle. To be able to laser engraving glass, its energy density must be greater than the glass damaged a critical value, also known as the threshold, and the laser energy density somewhere and it's about the size of the point of the spot, with a laser beam spot is smaller where the energy density produced greater. Thus, by properly focused, it could make the energy density of the laser before entering the glass and reaches the processing zone below the damage threshold of the glass, and then processed in the desired region exceeds the critical value, the laser in a very short period of time to produce a pulse, its energy can be broken in an instant to make the crystal is heated, resulting in a very small white spots inside the glass carved out of a predetermined shape, and the rest of the glass or crystal intact intact. In fact, this is the laser engraving assisted imaging technique. With the development of technology, it is expected to achieve a color engraving.
Color crystal engraving
Crystal glass engraving work becomes richer in color it is inevitable. Engraving crystal glass products utilizing part of the light has a strong reflection, refraction, and the blank portion of the light has good permeability optical principle can by micro-control circuit in accordance with the principle of three-color palette, a few were controlled colors of light, in the "engraving" image blending, change a variety of brilliant colors, so that the original engraving white image showing a colorful, dazzling effect.
