Optical Polycarbonate lenses for Camera High Transmittance high quality          The polycarbonate ,with its unique high light transmittance, high refractive index, high impact resistance, size stability and easy processing, occupies an extremely important position in this field. The optical lenses made of optical polycarbonates, not only can be used in cameras, microscopes, telescopes and optical test equipment etc, but also be used in office equipment and appliances fields such as movie projector lens, duplicator lens, infrared automatic focus projector lens, laser beam printer lens, various prism, and multi-faceted mirror and so on. And its application market is extremely wide.        The polycarbonate has another important application. That is the material of lens for children glasses, sunglasses, safety mirrors and adult glasses in optical lenses. In recent years, in the world glasses industry, the annual growth rate of polycarbonate consumption has remained over 20%, which shows great vitality of market.                         Charateristics of Polycarbonate board:        Impact resistance: The impact of PC board up to 3kg/cm. The impact strength of PC board is 250-300 times as common glass, is 20-30 times as acrylic sheets, is 2 times as toughened glass. And almost it’s no fracture risk. Falling the hammer with 3kg and two meters above it, that’s no crack. So it enjoyed the reputation of being of "safety glass" and "ring steel".          Resistance to flammability: PC board itself is not spontaneous combustion and have automatic quench. It accord with European Union ROHS instruction and strict UL safety standard, and UL94 fire prevention grade up to levelV0, levelV2, level HB. PC board itself is lighted 580°C. Remove from the fire source, it will be self-extinguish. It won't produce toxic gases, nor foster the fire spread when it’s burning.           Energy Saving: It keeps building cool in summer, and it keeps them warm in winter. The thermal conductivity (K value) of PC board is less than common glass and other plastics. The effect of heat insulation is 7%-25% higher than glass with equal level. The rate of heat insulation is highest to 49%. Thus it can reduce heat loss greatly, suit for buildings with warm equipments, belongs to environmental protection material.            High refractive index
