Focus Lens CO2 laser cutting machine features:! Import antireflection film processing technology through the high quality, stable performance materials:! CO2 imports of zinc selenide (ZnSe) focusing lens specifications: effective focal length (EFL) Tolerance: ± 2% Dimensions Diameter tolerance: +0.000 "-0.005" thickness ± 0.010 "edge thickness variation (ETV) <= 0.002" Aperture :( polished) 90% surface type precision diameter :( radial deviation / irregularity) @ 0.63μm plane side: a convex side stripe striped /0.5: changes in surface quality with a radius of 20-10 antireflection film reflectivity / surface @ 10.6μm <= 0.20% energy saving lamps require laser marking anti-counterfeiting technology in environmental protection and energy saving lamps LED on is has a unique advantage, compared to ordinary bulbs: diminished power fiber laser coders Humen brand, but energy savings are generally higher: usually 8w energy saving lamp power consumption equivalent to conventional bulbs 16W power consumption. But according to Xinhua Guizhou reports: CFL passing rate less than 50% by mass worrying! Xinhua Guiyang, February 15 (Reporter Li Qian Yu) Guizhou Industry and Commerce announced sampling of recent energy-saving lamp market situation shows that the passing rate of less than half of energy-saving lamps. Remind the business sector, the purchase of energy-saving lamps to be spotted identify fiber laser coders, the failure of energy-saving lamp life is short, and not saving. Guizhou AIC has drawn 65 batches of energy saving lamps (lamps), the presence of substandard batches of 37 indicators, the failure rate was 57%. From sampling situation, the presence of energy-saving lamps lamp power, energy efficiency rating and other identification confusion, poor quality power cable, operator incoming inspection and acceptance certificate and invoice or poor execution, the product involves a number of brands. Sampling staff analysis, from the lamp power, the initial luminous efficiency, energy efficiency rating and other substandard indicators look Changan fiber laser coders accessories, there is some enterprises in order to raise prices to low-power light indicates that power is increased, the product difference compared with rated power It is large; some companies to reduce costs, with ordinary halogen calcium phosphate powder instead of high energy-saving effect of the three-color phosphor, so that the luminous flux up to standard, when the user started using the brightness is good, but soon slowly down the dark, And life is short. Humen fiber laser coders brand, fiber laser coders, laser light is provided by a small clan of Dongguan City, a small family of laser equipment Limited. Dongguan City, a small family of laser equipment Limited (www.laser6000.com) strong, credible, in Dongguan, Guangdong and other welding equipment and equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead a small family of laser and you hand into the brilliant, for a better future!
