Description
- Eliminates haze.
- Serves as a lens protector.
- Hardened optical glass.
- 4 times the breaking strength.
- 8 Layer Waterproof Multi-Coating.
Absorbs the ultraviolet rays which often makes outdoor photographs hazy and indistinct. A muliti-purpose fine-weather filter for color as well as black and white films. Also serves as a permanent lens protector. Hardened Glass: Hardened optical glass that has 4 times the breaking strength in ANSI standardized testing (ANSI Z80.3 : 2001) where a steel balls of varying size and weight were dropped from a height of 50 inches onto the glass. Hardened 8 Layer Waterproof Multi-Coating that is Scratch & Stain Resistant: Newly developed industry leading 8-layer multi-coating yields an average light transmission rate of 99.35% between 400 and 700nm (visible spectrum). These coatings greatly reduce reflections off the surface of the glass allowing you tocapture more light in your photos. As with all HOYA multi-coatings, HD HMC is applied in a furnace at high he at, bonding the coating to the surface of the glass. This process is called "hard coating" and it is far more durable than other coating techniques.
