Abstract: Fluid mechanics principle about the optic micro-lens generated on needing positions is researched.A set of surface equations of optic glue drip,which spreads on horizontal plane under surface tention,is given.The equations set reflect relationships between coordinates of an arbitary point on the surface.A numerical calculation method of the equations set is proposed.Some surface shape parameters of the glue drip are calculated for different performance parameters,such as volume,contact angle and character length.Some shape curves and curvature radius curves are given.Results show that the contact angle and character length decrease,spread radius increase and thickness decrease,and non-sphere performance is strengthened.The intensity of the micro lens increases and the contact angle and character length decrease by mixing appropriate amount nanometer quartz powder into the glue.The bond strength between the glue and the glass increases and the contact angle decreases by milling or roughing the glass face.
