Ophthalmic lens tinting machine
Programmable machine for solid and graduated tinting of ophthalmic lenses
APPLICATION SECTORS
optics (lenses, sun lenses etc.)
The machine is made of AISI 304 stainless steel (EN 1.4301) throughout. This unit uses water-soluble dyes. IRIDE LAB can create solid and graduated tints of any intensity required. The unit is composed of nine 8-litre pots, each designed to hold up to 4 pairs of lenses. The pots can be replaced with pots containing a different dye in just a few minutes. Each pot rests on a heating plate that keeps the dye at the preset temperature. A laminar flow circulation system keeps the dye constantly in motion, avoiding turbulence but maintaining uniform dye distribution. A suitably designed overflow keeps the dye level constant. The automatic evaporation compensation replenishment system operates without affecting the dye temperature. Each pot has is own IRIDE GRAD lifting system, designed to follow all operator-programmed process curves. Tinting curves can be customized in terms of solid or graduated tints, colour, intensity, and size and position of the transition zone, and even in accordance with the lens material and type. Once the tinting process has been programmed, it can be stored on a PC and retrieved as necessary. The electromechanics of the lifting system ensure soft movements along its whole path, so as to prevent the creation of horizontal lines. The unit is also equipped with an extractor hood to remove fumes and a containment tray to prevent spillage of chemicals. The system is fully automatic and is controlled through a PC interface.
