The Hoya 77mm UV and IR Cut Filter allows only the visible spectrum of light rays to enter the camera and get captured by the sensor. It does this when the lens filter is attached to your lens. Both higher frequency ultraviolet rays and lower frequency infrared light rays are blocked out by using the UV and IR Cut Filter. the CCD and CMOS sensors found in our cameras are extremely susceptible to catching UV and IR rays, there just outside the visible spectrum and have a very negative impact on image quality.

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 remodelled. 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 colour 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, colourless 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 over layer is thick, so this filter doesn't suit use by a wide-angle lens. It is suitable for heavenly body photography.

Key Features:

• Produces better accuracy of colour in digital images than found in most traditional IR filters, when using colour CCD or CMOS camera sensors that are particularly susceptible to UV and IR rays.

• Only cuts through those light rays that fall within the visible spectrum of light, this filter blocks both ultraviolet rays found below 390 nm, as well as infrared rays above 700 nm

• This combination filter cuts through atmospheric haze to a greater degree than otherwise found.

• Compatible with stackable standard filters for a better combination of effects.

• Provides support with low-profile and a rigid aluminium filter ring.

An Important Note Regarding Wide-Angle Lenses:

Increasing the angle of incidence, meaning light rays entering the filter from an extreme angle as is the case with super-wide and ultra-wide angle lenses, leads to an increasing colour shift as the angle increases. This is based on the physics of light and the nature of the coatings. All UV-IR cut filters have the same properties in this regard. It is not recommended this filter be used with lenses having a field of view greater than 60 degrees.

Please Note: The UV-IR CUT filter is intended for use with digital SLR cameras and cine cameras that do NOT have an IR filter installed in front of the sensor. Colour balance effects can occur when this filter is used with cameras that have an IR filter installed in front of the sensor. Please consult your camera's owner’s manual before use.

Available in sizes 49mm through 82mm.
