Gas-Assisted Embossing and UV Curing Combine to Make Microlens Arrays

Facebook Twitter LinkedIn Email

Technique may allow low-cost, high-throughput manufacturing.

Hank Hogan

Individual microlenses may be small, but a large array of them can have a big impact — and present some big challenges. Because microlens arrays are a key optical component in large-format LCD TVs and elsewhere, there is a need for low-cost and high-throughput manufacturing methods. As a variety of techniques have been tried, the challenges of each have become apparent. The least expensive methods suffer from control problems, while those offering the best control lack throughput or are costly. Researchers formed a microlens array using a method that integrated gas-assisted embossing and...Read full article
