IOL Materials
Each intra-ocular lens manufacturer faces a series of complex choices in deciding which material(s) to use for the production of intra-ocular lenses. The choice of materials includes: PMMA (Polymethyl methacrylate) Silicone (molded, using Optoform 80 or Nanoform 200) Hydrophobic polymers Hydrophillic polymers Factors in the choice of material include: Biocompatibility of the material with the [...]

Mold Insert Materials
Molding ophthalmic lenses is a complex process which requires the combination of (a) significant experience in machining precision molds / inserts (b) extensive expertise in polymerization processes, and (c) combining both of the above with successful ophthalmic lens designs in a controlled and repeatable molding process. Non-ferrous metals: Most molds / inserts are manufactured in [...]
Electro-Optics Materials
(Materials for machining with monocrystalline diamond) Electo-optics manufacturers require complex geometries combined with dimensional accuracy in the sub-micrometre range. The optical surface qualities needed are beyond the limits of conventional cutting tools. However, ultra-precision machining using single crystalline diamond tools allows: the manufacture of complex geometries surface roughnesses in the nanometer range dimensional accuracies in [...]
