The Hoya UV - IR Cut is a specialized filter that has the ability to cut both UV rays below 390nm and IR rays above 700mn leaving just the light rays in the visible spectrum passing through the filter and into the camera.
This filter is used on a digital camera and the video, which do not have an IR protection filter toward an image sensor or were remodeled. This is important because unfiltered CCD and CMOS sensors are extremely susceptible to UV and IR rays just outside the visible spectrum that can have a very negative impact on image quality.
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 visible 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.
The Hoya UV & IR Cut filter is available in sizes 49mm through 82mm.
