Haida NanoPro UV/IR Cut Filter 77mm

The Haida 77mm NanoPro MC UV/IR Cut Filter is a specialized ultraviolet and infrared control filter designed for both digital cinematography and still photography. When recording video with a CCD or CMOS camera, multi-stop neutral density filters are often employed to maintain proper exposure by compensating for increased light levels. This allows the camera lens’s iris to be widened, achieving a shallower depth of field. However, as more light is transmitted through multi-stop neutral density filters, visible light is progressively reduced, while infrared light continues to pass through. This imbalance increases the proportion of infrared light reaching the camera sensor, potentially leading to undesirable color shifts in the footage. These effects are especially noticeable in darker areas of the frame, such as shadows, where black tones dominate.

• Ultraviolet light waves are blocked at 390 nanometers, reducing bluish cast of daylight when recording video or still photos.
• Useful with CCD or CMOS sensors, infrared light waves are blocked at 750 nanometers to filter out infrared light pollution that cause color shifts frequently associated with high-definition recording with multi-stop neutral density filters.
• Does not require adjustments to exposure while in use.
• Eight layers of interference coatings on both front and rear surfaces limit light that falls on a digital camera sensor to the visible spectrum.
• Constructed from optical glass for clarity as well as color fidelity.
• Multi-coated to prevent internal ghosting and reflections.
• Nano coating provides an additional layer that results in an improved beading effect when in contact with water or oil for greater cleaning efficiency.
• Thin, aluminum-alloy filter ring helps to prevent vignetting while remaining durable and lightweight.
• 77mm front filter threads allow for use with other filters.
• Plastic filter case for storage and transport.
