Tokina Cinema uses the proprietary ACCU-ND world class electrolytic coating to deposit rare earth metals onto the glass surface to create hyper neutral density filters that have industry-leading virtually zero color shift. They have exceptional IR attenuation across the visible spectrum and well past near IR. The deposit method holds neutrality that is free of color shift over time.
ACCU-ND technology has been used on major feature films, commercials, TV shows, and independent projects that demand the full color spectrum designed by the camera manufacturer without IR light contamination.
