Formatt 4x4" CC025B Color Compensating 025B Blue Schott-Desag B270 Crown Optical Glass Filter

• Color Correction filters are specifically designed to affect the color sensitivity of film emulsions

• A typical designation for one of these filters is CC30M; The "CC" stands for Color Compensating; The "30" stands for a density of 0.30 and the "M" is for magenta

• Formatt manufactures three types of Color Correction Filters - Color Temperature Conversion, Light Balancing and Color Compensating

• Optically consistent from filter to filter

• Formatt filters use the finest materials together with state of the art production techniques; This has resulted in a standard of optical perfection unmatched anywhere else

• All Formatt filters are manufactured using Water White Schott optical glass that is precision polished and ground to ensure absolute optical flatness and optimum performance

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.
