Tiffen 105mm Coarse Thread Hot Mirror IRND 0.9 Filter (3-Stop)
Key Features
  • Enables Use of ND without IR Pollution
  • Maintains Color Fidelity
  • For HD Camera without Internal IR Filter
  • ColorCore Water White Glass
The Tiffen 105mm Coarse Thread Hot Mirror IRND 0.9 Filter is a combination of both a hot mirror infrared (IR) control filter and a 0.9 neutral density (ND) filter. A hot mirror IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination. When using a standard ND filter to counter the increased light sensitivity afforded by the HD sensor, the effects of IR pollution become more apparent. This filter combines an ND filter with a comparable IR control filter to eliminate the spill of IR light reaching the sensor while still maintaining the extra exposure benefits of an ND filter. The hot mirror filtration incorporates a dielectric mirror in order to combat the effects of both near and far IR regions of the spectrum.

Tiffen W105CHMIRND9 Overview

The Tiffen 105mm Coarse Thread Hot Mirror IRND 0.9 Filter is a combination of both a hot mirror infrared (IR) control filter and a 0.9 neutral density (ND) filter. A hot mirror IRND is ideal for HD cameras, which have greater low-light sensitivity and, subsequently, an increased susceptibility to IR contamination. When using a standard ND filter to counter the increased light sensitivity afforded by the HD sensor, the effects of IR pollution become more apparent. This filter combines an ND filter with a comparable IR control filter to eliminate the spill of IR light reaching the sensor while still maintaining the extra exposure benefits of an ND filter. The hot mirror filtration incorporates a dielectric mirror in order to combat the effects of both near and far IR regions of the spectrum.

This filter is constructed from Water White glass and is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

IR control filter helps to block IR pollution from affecting the color fidelity of imagery; this enables a wider color gamut and truer colors, especially noticeable in the darker regions of the image.
0.9 ND filter provides a 3-stop exposure reduction.
Ideal for use with HD cameras without an integrated IR-blocking filter.
Hot mirror filter blocks IR pollution from both near and far regions of the spectrum while allowing all visible light to pass.
