Ice 150 x 150mm UV/IR Cut Filter

The Ice 150 x 150mm UV/IR Cut Filter is an ultraviolet and infrared control filter that is useful for digital cinematography and still photography. While recording video with a CCD or CMOS camera, multi-stop neutral density filters are used to maintain proper exposure by compensating for increased light levels when widening the camera lens' iris to obtain a narrower depth of field. As the increased amount of light passes through multi-stop neutral density filtration, visible light is progressively blocked, while infrared light is allowed to pass through. As the proportion of infrared light that reaches the camera sensor becomes greater, the results can show unwanted color shifts, particularly in dark areas of the frame, such as shadows where the appearance of black is dominant.

When the Ice 150 x 150mm UV/IR Cut Filter is applied, ultraviolet light waves and infrared light waves are suppressed, helping to ensure that light falling on a camera sensor is limited to the visible spectrum. When used along with multi-stop neutral density filters, potential infrared color shifts are prevented or minimized, preserving color accuracy throughout the frame. This filter may also be used to help ensure that the appearance of unwanted blue casts is reduced while recording video or still photos under daylight that also features intense ultraviolet light.

This filter cuts UV rays below 390nm and above 750nm, providing 99.4% light transmission between 400-700nm. The front surfaces of the filter include seventy layers of interference coatings, which limit the light that falls on a digital camera sensor to the visible spectrum. This filter is constructed from optical glass for clarity and color fidelity. This 150x150mm filter is 2mm thick and fits filter holders, including the Haida Haida M15, Kase K150P, LEE SW150, and more.
