About Tiffen Hot Mirror/IRND Filter

Let the Tiffen 4 x 4" Hot Mirror IRND 2.1 Filter elevate your photography and cinematography experience. This high-quality, durable filter is designed to be versatile and effective, offering a true neutral density that extends beyond the visible range into the near infra-red.

The Hot Mirror (HM) filter can be used individually or stacked with Tiffen's innovative IR ND Filters (IRND), or even as a comprehensive Hot Mirror IRND all-in-one combination filter (HMIRND). This flexibility allows photographers and cinematographers to adapt to a variety of lighting conditions, ensuring optimal image quality at all times.

The IRND filters are a testament to Tiffen's unique ColorCore technology, which encapsulates the coating within the filter. This feature not only enhances the filter's durability but also allows for easy cleaning without the risk of damaging the filter, a common issue with surface-coated filters.

Crafted from the finest optically pure glass, these filters are ground and polished to the highest possible standards of flatness and perfect parallelism. This meticulous attention to detail ensures that the IR ND filters and IR 85ND filters effectively eliminate Infrared bleed above 700nm. This is a crucial feature for high-definition cameras, allowing for the use of heavier grades of Neutral Density filters while maintaining complete color balance.

Tiffen filters are trusted by professionals worldwide and are used in almost every major movie and TV production. The brand's commitment to quality and innovation has been recognized with multiple awards from the Academy of Motion Picture Arts and Sciences and the Academy of Television Arts and Sciences. With the Tiffen 4 x 4" Hot Mirror IRND 2.1 Filter, you're not just investing in a piece of equipment, but a legacy of excellence in filter technology.
