The production of ophthalmic lenses requires different marking processes. For example, technical engravings or brandings for spectacle lenses. For contact lenses the UDI marking is a FDA requirement. 3D-Micromac offers ophthalmic marking solutions for laser engraving of all types of ophthalmic lenses, e.g. prescription and sunglasses, or contact lenses. All systems use UV lasers for permanent marking  and guarantee:
Reliable process stability
Highest engraving precision
Accurate contrast adjustment
Maximum throughput
Top availability
Flexibility in system configuration
Simple retrofitting
The customer can choose between premium quality excimer laser systems and high quality maintenance-free DPSS laser systems. Both are suitable for production of technical engravings and visible brandings on blocked and unblocked lenses as well as contact lenses. Using excimer laser systems the engravings will be generated by cold laser ablation of 193 nm UV radiation. This results in a superior engraving quality considering all cosmetic aspects without any heat affection and micro cracks.
