The anti-counterfeiting market is growing rapidly, and microlens arrays are consistently ranked among the most secure optical technologies available. Their unique combination of overt and covert effects makes them incredibly difficult to replicate. Now, that formidable level of protection doesn't have to come from an outside supplier. The strategic advantage is unlocked by bringing microlens production in-house. This gives you ultimate control over your security, IP, supply chain, and costs...

In optical films and holography, “recombination” sounds esoteric, but it is simply the point where ideas in the design office become real square metres of structure. It is also where most projects quietly succeed or quietly die. Two families still dominate: thermal recombination and UV recombination. Both can produce good work. Both have long production histories. But they behave very differently once you start asking for tighter tolerances, higher brightness and more demanding substrates....

We have now upgraded the platform with higher speed and improved angular control. In practical terms, this means tighter registration and more predictable results when scaling a master. The attached video provides a brief view of the upgraded system in operation. At XRD Nano, we take a long-term view. We keep proven machines current by integrating new technology where it adds measurable value, and we continue to add capability to new machines so customers can produce distinctive masters for...
