Product Highlights

  • Enables Use of ND Without IR Pollution
  • Maintains Color Fidelity
  • For HD Camera Without Internal IR Filter
  • ColorCore Water White Glass




Unlike photographic film, the imaging devices in hi-definition cameras are inherently sensitive to infra-red light.


Because of this, IR pollution has become a significant issue, particularly for those hi-definition cameras that do not incorporate an internal IRThe Hot Mirror (HM) filter can be used individually, stacked with our new IR ND Filters (IRND), or as a Hot Mirror IRND all in one combination filter (HMIRND). Tiffen IRND filters provide a true neutral density beyond the visible range into the near infra-red. IRND filters incorporate Tiffen’s unique ColorCore™ technology that sandwiches the coating within the filter and allows for easy cleaning without fear of damaging the filter as with surface coated filters. These innovative new filters are made from the finest optically pure glass and are ground and polished to the highest possible standards of flatness and perfect parallelism.

IR ND filters and IR 85ND filters eliminate Infrared bleed above 700nm. This is particularly important as it now allows for the use of the heavier grades of Neutral Density filters needed for these hi definition cameras while, at the same time, maintaining complete color balance.

Tiffen’s new Hot Mirror filters (HM) are available as a stand alone filter or in combination, as HMIRND.3, HMIRND.6, HMIRND.9, HMIRND1.2, HMIRND1.5, HMIRND1.8, and new HMIRND2.1.

Available in popular motion picture sizes.

Tiffen filters are used in almost every major movie and TV production around the world. Tiffen has been honored with two Technical Achievement Awards from the Academy of Motion Picture Arts and Sciences: one for innovative product design, and the other for its unique lamination process which gives complete control over filter color and density. In 2000, the Academy presented Nat Tiffen with a Scientific and Engineering Award for consistency in filter quality. Tiffen also received a 1998 Emmy Award for Engineering Excellence, as well as numerous awards for innovation filter technology. blocker. To combat this issue, Tiffen has developed a special Hot Mirror filter that completely blocks IR thru the entire spectrum. These Hot Mirror filters are the perfect solution for IR pollution with no appreciable reduction in visible light transmission.




The Tiffen Hot Mirror IRND 0.3 Filter is a combination of both a hot mirror infrared control filter and a 0.3 neutral density 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 neutral density filter to counter the increased light sensitivity afforded by the HD sensor, the effects of infrared pollution become more apparent. This filter combines an ND filter with a comparable IR control filter to eliminate the spill of infrared light reaching the sensor while still maintaining the extra exposure benefits of a neutral density filter. The hot mirror filtration incorporates a dielectric mirror in order to combat the effects of both near and far infrared 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 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch.


Infrared control filter helps to block infrared 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.
     0.3 neutral density filter provides a 1 stop exposure reduction.
Ideal for use with HD cameras without an integrated infrared-blocking filter.
Hot mirror filter blocks infrared pollution from both near and far regions of the spectrum while allowing all visible light to pass.




IR pollution is a significant issue in many of today’s hi-definition cameras which are inherently sensitive to infra-red light, particularly those that do not incorporate an internal IR blocker (single CMOS cameras). The TIFFEN Hot Mirror Infra-Red Neutral Density (HMIRND) Combination filter is the COMPLETE solution to the IR pollution problem addressing this issue in both the Near IR and IR regions of the spectrum. Each HMIRND filter blocks unwanted IR light and has matched IR and ND components to assure accurate color reproduction in the near infra-red region. In addition, The Tiffen Hot Mirror (HM) filter is offered as a stand alone filter for those looking to block just the IR portion of the spectrum, with no appreciable loss of light transmission.

 

TIFFEN Hot Mirror and Hot Mirror IRND combination filters incorporate Tiffen’s uniqueColorCore™ technology that sandwiches the coating within the filter and allows for easy cleaning without fear of damaging the filter as with surface coated filters. These innovative new filters are made from the finest optically pure glass and are ground and polished to the highest possible standards of flatness and perfect parallelism.


Tiffen’s Hot Mirror (HM) and Hot Mirror Infra-Red Neutral Density (HMIRND) Filters are available in popular motion picture sizes and 77mm wide angle. HMIRND Filters are available in 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, and 2.1 Densities.

 

NOTE: TIFFEN Hot Mirror (HM) Filters can be stacked with TIFFEN Infra-Red Neutral Density (IRND) Filters – Introduced in 2007 - to achieve the same results as the all in one combination TIFFEN Hot Mirror Infra-Red Neutral Density (HMIRND) Filters.

 

 




The Tiffen Company, the industry leader in photographic glass filters for the Motion Picture and Broadcast industries for 70 years, has done it again with its latest innovation in filter technology.  Tiffen has now addressed the problem of IR pollution with the introduction of its exclusive Hot Mirror and Hot Mirror IRND filters. Unlike photographic film, the imaging devices in hi-definition cameras are inherently sensitive to infra-red light.

Tiffen Hot Mirror Infrared Neutral Density Filters 0.3-2.1 reduce the amount of light passing through the camera lens without changing the color of the scene, while also reducing the amount of infrared light entering the camera. Especially useful in bright light conditions to help prevent over exposure. Allows proper exposure at wider lens openings, for reduced depth-of-field, and to highlight a key subject by making foreground and/or background out of focus. Permits slower shutter speeds for blurred motion effects in still photography.


The introduction of the hot mirror enables powerful filtration that is unparalleled to conventional IRND filters.
