METHOD FOR PROVIDING ANTIREFLECTION FILM ON SYNTHETIC RESIN LENS

摘要

PURPOSE:To obtain a film thickness layer having good uniformity by changing a pulling speed with the angle between the liquid surface of an organopolysiloxane resin soln. and the lens face. CONSTITUTION:An organopolysiloxane resin layer is dip-coated on a synthetic resin lens. The pulling speed is changed according to the contact angle between the lens surface and the surface of the coating soln. in this stage. The figure shows relative diagram between the contact angle and the pulling speed.
