Requirements and effect of lens coating

Plus Film Workshop and hardened workshop on the environment requires a high degree of. Are used no dust environment, are pressure airflow, makes dust full caot into, on workshop of temperature, and humidity has instrument strictly of monitoring regulation, because plating film on lenses of clean degree rely on is large, slightly dust of lenses surface plating film Hour easy shedding formed surface highlights, so staff wearing special of electrostatic clothing, prevent exteal environment into workshop Si will hair Sang of dust fall to Cheap Ray Ban Sunglasses lenses Sang, Coating before United Kingdom clean lens apart piece by piece with high pressure air guns, implied by removing surface impurity, and officers confirm that the lens is in line with coating conditions, qualified on the coating of the lens hood, and operations persoel film workshop is not even free to speak, avoid saliva contamination lenses.

Ian sequence steps ended Hour, lenses was into imports vacuum plating film machine, perfect of sealed sexual can makes machine within reached height vacuum State, main used of is ion vacuum plating film technology, advanced of ion source bombardment (with argon ion) makes lenses surface reached clean and no rugged of phenomenon, such makes sputtering up of film layer can full of and lenses bonding, to reached firmly of effect, automatic of production can strictly to control film layer of color of consistency, plating film Hour of Cheap Ray Bans lenses apart from beautiful , Can has various color outside, most main features is reduction anti-increased through, elimination no plating film lenses surface will produced of reflective phenomenon, increased into people eye of light, make wearing who depending on property more clear bright, seven to nine layer of plating film material makes eventually lenses can has high strength, and 96%-99% of high transmission rate, and anti-electromagnetic waves radiation, and waterproof anti-fog, multiple effect.

Each batch plating film of lenses end Hour, also to sampling lenses film layer of adhesion, and wear degrees and firm degrees, detection requirements are must above GB, to wear for cases, is used 0000# wire down, weight about 750g in must of speed down back mill 1 minutes, number about 120 times around, test of results is with within eye observation is has mill hurt of traces, wear test of purpose is make wearing who in using wipe films hard wipe out classified hurt, such lenses of hardness will qualified, certainly film layer of firm degrees also critical, with 4.5 % Salt water (pure water) at 100 degrees c conditions for 12 minutes every two minutes to come up with stimulus 20 seconds of immersion in cold water, then put into boiling salt water, repeated 6 times, watch for stripping, inspection and testing of qualified Ray Ban Sunglasses to be approved into the packaging sector, prepare reporting-as-finished.
