The following UV370 - ultraviolet absorption optical glass coating uv main features:

Raw materials: ultraviolet optical glass, optical properties

Color: optical flat flatness, the better the lens itself color reduction

The surface of the glass: parallelism and aperture have reached the top standard

Antireflection film: double-sided multi-layer + waterproof, original "U" type coating

Black: black lens edge circle, reduce the stray light

Very low reflection: through rate ≥ 99.2% ≤ 0.3%, reflectivity

High quality mirror ring: milling flower frame, matte black optical grade oxidation
