PC LENS (POLYCARBONATE)
We have both goodquality and competitive price.

Characteristics:
It is converged by flexible carbonic ether annulations and unmovable dual phenol. It's molecular weight is between 20000-38000. The refractive index under test condition of 25c is 1. 586The lens made by this type of material is called space lens.

Advantages:
1. Light: 57% lighter than traditional glass lens:
2. Safe: It's performance of impact-resistance 60 times of glass lens. And the thickness in 2. 5cm can be made into bullet-proof glass.
3. Thin: The thinness is equal to cr-39lens high index1. 6.
