PROPERTY TESTING APPARATUS FOR PHOTOCURABLE RESIN, RETAINER USED IN THE TESTING APPARATUS AND PROPERTY TESTING METHOD

摘要

A retainer for use in measuring a force generated between a photocurable resin and a pressing member by a detector includes: a pressing member that has light transmission characteristics and is pressed to the photocurable resin; and a light irradiation block that is provided between the detector and the pressing member and irradiates light emitted from an external light source onto the pressing member in a state of being not contacting a light source and an optical transmission line including an optical fiber.
