HOYA UV & IR Cut 77mm filter

HOYA UV & IR Cut 77mm filter

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. Filters of this nature are used mainly in cinema and video production because many of these cameras do not have a built-in IR filter in front of the image sensor. 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 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. Filters of this nature are used mainly in cinema and video production because many of these cameras do not have a built-in IR filter in front of the image sensor. 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 effect of the filter is achieved mainly though the multi-layer coatings on the surface of the filter. Hoya begins with crystal clear, colorless optical glass and then bonds coating to this filter that block both UV and IR light rays outside of the range mentioned.

There is light incidence angle dependence in the transmission factor because overlayer is thick, so this filter doesn't suit use by a wide-angle lens.

It is suitable for heavenly body photography.
