During stunts which can damage a lens, Schneider Optical Flats protect expensive front elements and other filters while providing the truest image, free of unwanted color shifts. The Schneider Optics 6.6x6.6 In. Optical Flat Clear Glass Filter made from Schneider's clear optical glass, these filters minimize or eliminate the need for laboratory color correction caused by filter variations. Both the front and rear surfaces of these solid-glass (non-laminated) filters receive Schneider's hard anti-reflective (AR) coating, which measurably improves light transmission.
