Method for measuring optical property of transparent flexible substrate, involves scattering incident light beam on substrate in mounting surface and measuring scattered light received by receiver from substrate at preset angle

摘要

A light beam (1) from a light source (2) is transmitted on transparent flexible substrate (3), and the transmitted portions of beam from substrate are received as light rays (4) in a receiver (5) and subsequently evaluated. The light beam is transmitted to a substrate mounting surface (8) at an incidence angle with respect to plumb (7). The incident light beam is scattered on substrate in mounting surface and the measurement of scattered light (9) received by receiver from substrate at preset angle is performed.
