Tiffen 4 x 4" Hot Mirror Filter

You can now effectively address the issue of infrared (IR) pollution in high-definition cameras with Tiffen's exclusive 4 x 4" Hot Mirror and Hot Mirror IRND filters. Unlike traditional photographic film, the imaging sensors in modern high-definition cameras are naturally sensitive to infrared light. This sensitivity can lead to IR pollution, a significant concern especially for cameras that lack an internal IR blocker.

Tiffen's innovative Hot Mirror filter is specifically designed to combat this issue, offering a comprehensive solution that blocks IR across the entire spectrum. These filters are the ideal remedy for IR pollution, ensuring no appreciable reduction in visible light transmission.

The 4 x 4" Hot Mirror (HM) filter can be utilized individually, stacked with Tiffen's new IR Neutral Density (ND) Filters (IRND), or combined as a Hot Mirror IRND all-in-one filter (HMIRND). Tiffen's IRND filters deliver a true neutral density beyond the visible range, extending into the near infrared.

These filters are crafted using Tiffen's unique ColorCore technology, which embeds the coating within the filter. This innovative design allows for easy cleaning without the risk of damaging the filter, a common concern with surface coated filters.

Tiffen's filters are made from the finest optically pure glass, ground and polished to the highest standards of flatness and perfect parallelism. The IR ND filters and IR 85ND filters effectively eliminate infrared bleed above 700nm. This feature is crucial as it allows for the use of heavier grades of Neutral Density filters required for high-definition cameras, while maintaining complete color balance.

Tiffen's 4 x 4" Hot Mirror filters (HM) are available as a standalone filter or in combination, as HMIRND.3, HMIRND.6, HMIRND.9, HMIRND1.2, HMIRND1.5, HMIRND1.8, and HMIRND2.1. These filters are the perfect solution for photographers and videographers looking to achieve the highest quality images and videos, free from the effects of IR pollution.
