Abstract

método de revestimento de lentes com lenslets com um controle melhorado do deslocamento de potência. um método de revestimento de uma pluralidade de lentes ópticas tendo pelo menos uma superfície principal pelo menos parcialmente coberta com lenslets, o método compreendendo: - imersão (dip) de pelo menos uma primeira lente óptica da pluralidade de lentes ópticas em um fluido de revestimento, - retirada (wdw) da, pelo menos uma, primeira lente óptica do fluido de revestimento a uma velocidade de retirada controlada, - medição (meas) de uma espessura de uma camada de revestimento depositada na, pelo menos uma, primeira lente óptica, - determinação (adj) de uma velocidade de retirada ajustada com base na espessura medida, e - repetição das etapas de imersão (dip), retirada (wdw), medição (meas) e determinação (adj) em pelo menos outras lentes ópticas da pluralidade de lentes ópticas, usando a velocidade de retirada ajustada durante a etapa de retirada (wdw).
