Laser Engraving Crystal

Crystal engraving is the laser to the laser machine will be a certain wavelength into the crystal, crystal makes specific parts of the inner fine bubbles burst, and sketched out a crystal processing preset shape, also refers to this process of crystal crafts.
Crystal laser engraving principle
These glass and crystal crafts are made by computer controlled laser engraving machine. As a matter of fact, most of the handicrafts we see are not genuine crystals, but man-made crystals. "Laser" is the most useful tool for "inner carving" of artificial crystals (also called crystal glass). Laser engraving technology is used to engrave plane or three-dimensional patterns in the inner part of crystal glass.
Sculpture is an ancient art, carving techniques are carved from the outside, from the outside of the material carved out of the desired shape, while the laser can be like Sun Wukong, "deep into the hinterland" to show their hands and feet. Careful observation of these glass crystal products, not completely around the "open for knife" and, in this regard, laser than Sun Wukong also a monkey into someone's belly when there are gaps do! Laser engraving principle is also very simple. Can be laser engraved glass, its energy density must be greater than a critical value, the glass damage threshold and laser or, somewhere in the energy density associated with it in the same spot size of a laser beam spot, the smaller places produce more energy density. In this way, through the appropriate focus, can make the laser energy density before entering the glass and reach the processing zone below the damage threshold of the glass, and in the hope of processing area is more than the critical value, the laser pulse is generated in a very short period of time, the energy will instantly make the water crystal heat burst, resulting in small white spots inside the glass, carved out of a predetermined shape, while the rest of the glass or crystal will remain intact. In fact, this is the laser assisted imaging technology. With the development of technology, color engraving is also expected to be realized.
Colored crystal inner carving
It is inevitable that the inner sculptures of crystal glass become more colorful. The carved crystal glass handicraft has a strong effect on the reflection and refraction of light, optical principle and the blank part has better performance on the transparent light, by the micro control circuit in accordance with the three color palette principle, respectively, control of several colors of light, color mixing in "carving" image, a variety of beautiful changes color, so that the original image carved white showing the effect of a riot of colours, The brightness dazzles the eyes.
