Laser anti-wrinkle is controlled by computer, low carbon dioxide laser energy, can accurately control the depth of the skin surface vaporization, complete separation vaporization, no carbide anti-wrinkle facial skin care technology. Laser technology is used to eliminate wrinkles, it is after laser technology applied to clinical, and after improvement, improve, and constantly updated results. Laser optical filter is used to eliminate wrinkles technology already quite mature now. Automatic laser welding machine. If your frames is to be able to cooperate with automatic laser welding machine makes the corresponding fixture, and need large quantities of production quickly, then using automatic laser welding machine will be a good choice. With laser, spot welding machine, automatic laser welding machine needs to have a jig to cooperate, belong to the continuous seal welding, advantage is computer control, to achieve mass production quickly, can save a lot of time and manpower costs. And the automatic laser welding machine and do you have a hard and soft light road or YAG solid state laser and optical fiber transmission of the laser welding machine. Optical fiber transmission of the laser welding machine output would be more to the relatively stable, the price is more expensive, you can choose according to own actual situation accordingly. Color filter is usually installed in the front of the light source, make the human eye can receive light saturation of a color. With infrared filter, green, blue, etc. With UV filter, VD filter, compared to those who take the floorboard of color filter. Filter such as contrast, color filter, LB filter, etc. Working principle of the color filter is made from optical substrate, such as acrylic and polycarbonate and glass. Through the stack up, substrate and absorbent material or thin film deposition can staining; The coating can be passed or prevent special wavelength of visible light, infrared and near infrared spectroscopy, through color filters (red R) , green, G) , blue, B) Three kinds of color layer provides hue, form the color images. TFT LCD panels are able to produce color change, mainly from the color filter ( 滤色器; CF) ; The LCD panel is through the back light light penetrates it or not, and therefore produce picture, the picture presented at this point the only black, white dichromatic, in addition, still need through the color filter red ( R) , green, G) , blue, B) Three kinds of color layer provides hue, form color display screen.
