Method for coating lenses with lenslets with an improved control on power shift

Abstract

The disclosure relates to a method for coating an optical lens having a main surface at least partly covered with lenslets. The optical lens is dipped in a coating fluid, withdrawn to reach an initial position defined so that said main surface faces towards a first, horizontal, direction, and the coating fluid coating said optical lens is dried. After withdrawing the optical lens and before or while drying the coating fluid, the optical lens is tilted to a final position defined so that said main surface faces upwards towards a final direction having an angle comprised between 80° and 100° with respect to the first direction, the first and final directions defining a vertical plane. Alternately or in combination, while withdrawing said optical lens, part of the coating fluid is removed from the optical lens by sliding said optical lens along a mechanical blade.
