玻璃透镜的品质鉴定Quality appraisal of glass lenses
ITEM低端玻璃透镜Low-end glass lens高端光学玻璃透镜High-end optical glass lens from KINGLUX
加工工艺Processing Technology①无退火工序，透镜应力弱，防爆性能弱，易碎No annealing step ,lens stress weak , explosion-proof performance is weak , fragile①经过保温带工艺退火，透镜应力强，防爆性能好，不易摔碎After annealing process , the lens would be strong,good explosion-proof performance, and not fragile
②工序，模压-粗磨-倒边-抛光，所有工序均为一出多，产品精度低，一致性差 Process：  molding – roughing – bevelling – polished , all the processes are more than one , precision products is low, poor consistency②工序，原材料抛光-模压-退火-敲边-粗磨-倒边-精磨-抛光-超声波清洗，所有工序均为一出一，保证产品精度以及一致性   Process： polishing materials – molded – annealing – Knock side – roughing – bevelling – grinding – polishing – ultrasonic cleaning , all the processes ensure product accuracy and consistency
②普通模具材料，模压成型透镜表面精度低Common mold material  lens is of low surface accuracy ③透镜模具采用日本进口特殊模具材料，模压成型的透镜表面精密度高Japan imported special lens mold material ensure lens high surface accuracy 
原材料选择Raw material selection普通低价高硼硅3.3棒料，气泡，杂质，黑点，水纹等瑕疵多Common low-cost high borosilicate 3.3 bar , bubbles/ inclusions /black spots/waterlines and other defects more采用高端特级精品高硼硅玻璃3.3棒料，透光率高，无气泡，杂质，黑点，水纹等瑕疵  Using premium quality borosilicate glass 3.3 bar , high transmittance, no bubbles /impurities/ black spots/ waterlines and other defects
