Formatt BF6X6HM4 - HItech Glass 6.6x6.6

Formatt Hot Mirror Filter - Some digital still cameras can have increased sensitivity to infrared light that may cause color rendition problems. The Formatt Standard Hot Mirror filter is designed to remedy this problem by reflecting most infrared light.

- Prevents excessive infrared filtration from reaching the digital sensor of your camera

- Helps provides a truer digital image


Absorbing Cell Technology

- The secret to Formatt's consistency in filter design lies in its unique "Absorbing Cell Technology" (A.C.T.); this unique process allows color correct dyes to be applied to optically pure, wafer thin absorbing cells and offers a controllability that ensures the smoothest grad lines and consistent color across the whole filter surface.

- This process is revolutionary compared with conventional filter dying techniques by eliminating the need to directly coat the glass surface itself; the repeatable performance gained through A.C.T. ensures that at any time you have to swap like filters for like filters mid shoot you can do so with confidence with no discernable differences in color or density.

- Each filter is guaranteed flatness to a maximum 2-wave value and comes with an individual reading from a laser interferometer; every filter is carefully verified with a densitometer and spectrophotometer to ensure consistent and accurate transmission, before leaving the factory - the result is an absolute purity of image that eliminates any unwanted colorcast caused by conventional greenish soda-lime glass.
