METHOD OF DIP-COATING A LENS

摘要

A method of dip-coating a lens includes the steps of: immersing the lens (10) in a coating solution bath (2) having a horizontal coating solution surface (4), and withdrawing the lens (10) from the bath (2) through the solution surface (4). The step of withdrawing is performed with a movement of the lens such that the orientation of the lens (10) varies continuously, from a position in which the optical axis (A) of the lens (10) is inclined upwards and towards the concave surface (12) of the lens (10) when the lens (10) starts emerging from the bath (2) to a position in which the optical axis (A) of the lens (10) is inclined upwards and towards the convex surface (11) of the lens (10) when the lens (10) finishes emerging from the bath (2).
