Abstract

A method for coating a plurality of optical lenses having at least one main surface at least partly covered with lenslets, the method comprising: - dipping (DIP) at least one first optical lens from the plurality of optical lenses into a coating fluid, - withdrawing (WDW) the at least one first optical lens from the coating fluid at a controlled withdrawal speed, - measuring (MEAS) a thickness of a coating layer deposited on the at least one first optical lens, - determining (ADJ) an adjusted withdrawal speed based on the measured thickness, and - repeating the steps of dipping (DIP), withdrawing (WDW), measuring (MEAS) and determining (ADJ) on at least other optical lenses from the plurality of optical lenses, using the adjusted withdrawal speed during the withdrawing step (WDW).
