ULTRA PRECISION LENSES & OPTICAL PRODUCTS
Our strengths in advanced ultra-precision mould design, mould manufacture and moulding allow us to provide solutions ranging from multi-cavity optical moulds with demanding toricity tolerances and high volume, to single-cavity micro fresnel lenses with nanometer scale features, as well as optical tech for microfluidics.
Example: IOL lens casts, Contact lens casts, Blister packaging, etc.
MICRO FRESNEL LENS
The Micro Fresnel Lens shows our true capabilities in mould making. The 4-cavity mould produces a micro Fresnel lens with a diameter of 2.5 mm and runs fully automatically at a 6.5 second cycle time with auto degating. The surface features on the lens surface are between 450 nm and 910 nm deep, with the ability to go smaller.
OPTICAL INSERTS
Micro Systems can supply optical inserts for conventional and micro moulds. In certain applications, we can supply hardened stainless mould steel inserts, directly machined, without the need to carry out any manual polishing operations.
