Abstract

1284182 Photo-electric testing CANON K K 20 March 1970 [20 March 1969] 13731/70 Heading G1A [Also in Division H1] The haze ratio of a polyester film A is measured by first placing the film across the aperture 12 of an integrating sphere 11 and measuring the illuminance at a given wavelength for light passing through another aperture 14 and then moving the film to the other aperture and again measuring the illuminace of the sphere, Fig.2 (not shown).
