The Tiffen T1 127 mm infrared filter is a high-tech filter designed to eliminate infrared contamination at 680 nm. This filter will help you maintain your colour spectrum when shooting dark fabrics. You will notice that blacks appear true without colour cast from the red end of the spectrum.

This filter was created to capture a much broader colour spectrum than previous infrared filters - particularly with digital camcorders. Colour shift is a critical factor in digital photography, particularly when processing the infrared spectrum - and even more important when shooting in HD technology.

Unlike traditional cameras, the CCD or CMOS sensors of a digital camera are, by nature, sensitive to infrared contamination. Manufacturers attempt to avoid this problem by incorporating an infrared-absorbing filter above the image sensor. As these filters do not have a sharp cut-off at infrared wavelengths, a compromise must be made not to exclude visible red wavelengths. Despite these precautions, some infrared wavelengths pass through, resulting in image contamination.

Tiffen's Water White glass, using their ColorCore technology, is characterised by high transmission quality. Generally, it transmits 98 to 99% of light. It also features anti-glare and anti-reflective qualities that make it useful in a wide range of applications, including the film industry, shop windows and art exhibitions. The glass is virtually flawless and is becoming increasingly present in digital equipment.



- Helps eliminate red contamination on dark products and fabrics

- Ideal for digital photography

- Can be used permanently with most digital cameras

- Tiffen's ColorCore technology is produced by a process that involves permanently laminating the filter material between two pieces of optical glass ground flat to tolerances of one ten-thousandth of an inch, then mounted in precision aluminium rings
