HOYA, the world renowned optical glass manufacturer,
presents an innovative high definition line of filters..

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.
HIGH TRANSPARENCY POLARIZING FILM
The polarizing film is the same as that used in the latest high definition LCD TV screens.
It has 25% higher light transmission than standard polarizing film
used in current photographic filters.

 

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 to capture more light in your photos.
As with all HOYA multi-coatings,HD HMC is applied in a furnace at high heat, 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. The chemistry of the top layer is formulated not just to be more durable but to be resistant to oil stains. This means that finger prints and other oils are much easier to remove.
