Tiffen 4x5.65" T 1/2 IR Filter

Professional Infrared Control for Digital Cinema

The Tiffen 4 x 5.65" T1/2 IR Filter is a precision-engineered solution for digital cinematography, designed to eliminate near-infrared and infrared contamination. Modern digital sensors are highly sensitive to red hues, which often leads to unwanted IR light reaching the sensor. This contamination causes noticeable color shifts, particularly in shadows and dark areas where blacks can appear muddy or magenta.

By utilizing the T1/2 IR Filter, near-infrared waves starting at 680nm are reduced by approximately 45%. This attenuation continues until reaching a nearly flat state between 775nm and 800nm, ensuring only the visible spectrum reaches your camera sensor. This process preserves color accuracy and maintains deep, natural blacks across the entire frame without the need for dichroic coatings.

Built to the highest standards, this filter is crafted from Water White glass for superior optical clarity. Tiffen uses their proprietary ColorCore technology, laminating the filter substrate between 2 pieces of optical glass and grinding it to a precise tolerance of 1/10,000th of an inch. This ensures consistent performance and durability for professional production environments.
