UV-IR 55mm Hoya MC
HOYA has introduced the
new Hoya UV & IR Cut filter in 49mm through 82mm sizes. This
specialized filter has the ability to cut out both UV rays below 390nm
and IR rays above 700mn leaving just the light rays in the visible
spectrum passing through the filters and into the camera. This is
important because CCD and CMOS sensors are extremely susceptible to UV
and IR rays just outside the visible spectrum that have a very negative
impact on image quality.
The Hoya UV & IR Cut filter blocks
both UV rays and IR rays yielding clearer and sharper pictures outdoors.
This filter can reduce the effects of atmospheric haze to an even
greater degree than a standard UV filter.
The Hoya UV &
IR light transmission curve shows the sharp-cut nature of the filter
glass and coatings as well as the consistent light transmission in the
visible spectrum. This curve demonstrates a more even light transmission
than the closest competitor. This means that sharper images with more
depth and finer, richer color gradations are possible with the Hoya UV
& IR Cut filter.
