Abstract

The application relates to a method for calibrating an apparatus (10) for the additive production of an optical element, in particular a spectacle lens, in a printing process by applying droplets of printing ink (23), the apparatus (10) comprising a print head (12) with a print head nozzle arrangement (26) which has a plurality of print head nozzles (30.n.m) for producing droplets of printing ink (23). According to the invention, a mean droplet volume Vm of the printing ink droplets (23) is determined as a calibration variable of the apparatus (10) for additive manufacturing of the optical element. The invention also relates to the manufacture of an optical element, in particular an optical element from the group consisting of a lens, intraocular lens, contact lens, spectacle lens and an apparatus (10) for the manufacture of an optical element, in particular a spectacle lens.
