Overview

Overview

 The Tiffen Water White T1 IR Filter - 4x5.65 absorbs infrared energy, making it ideal for use with digital cinema cameras with sensor that are particularly sensitive to the IR spectrum. 

CCD and CMOS sensors are made from silicon, which is inherently sensitive to infrared energy; subsequently, digital camera manufacturers have worked diligently in making sensors that see only the visible spectrum. These cameras have very effective internal hot mirrors, blocking wavelengths above 700mm (a gradual cut off, intentionally made to preserve the red response).
 
NTSC and PAL formats have limitations (bright reds in particular) due to narrow bandwidth, and reds have a tendency to smear. However, with the advent of digital cinematography and digital television, today’s cameras need to capture a much wider color gamut. To preserve as much of the camera’s enhanced red response as possible, a small portion of light must pass through the edge of the visible spectrum, causing the camera to see red where the naked eye cannot. Opening up this color channel leaves images vulnerable to IR contamination (dark fabrics in particular), where greens become a reddish, muddy brown and blacks take on a magenta hue.
 
With the Tiffen T1 IR filter, capturing subtle hues of red are effortless, while maintaining crisp blacks and assisting the camera in capturing the wide color gamut for which it was designed, with minimal light loss (1/2 stop). The T1 IR filter is manufactured using Tiffen’s proprietary ColorCore™ technology, where each effect is captured between two pieces of Water White glass. This process allows Tiffen to grind and polish both surfaces, providing the cinematographer with perfect parallelism and worry-free handling.
 
NOTE: The T1 IR filter contains no dichroic coating, meaning it will not vignette green, magenta, or cyan at wide angles. The T1 IR filter can be stacked with Neutral Densities up to 0.9 (however, for best results, it is recommended to use the Tiffen Full Spectrum IRND’s if heavier densities are required).
