High definition:(a).the size
of nano metal oxide is ****0nm, and visiblerange is ******0 nm,less than visible range,
light through the lens is
the linear transmission, transmission rate is much higher than
the traditional lens.（b）.The lens
use CR**9 material,the refractive index is 1.*9, abbe numberas high as *8,blend in he
nanoparticles with high image quality
