Corning publishes a white paper "Improving iris recognition with liquid lens technology." The main highlights are:

  • Liquid lens-based AF allow the optical system to maximize the sharpness of an image. This compact, low-cost, and low-power solution extends the iris reading distance from a few millimeters to several meters.
  • COVID-19 has escalated the already growing demand for non-contact identification systems.
  • Liquid lenses possess a fast response time, as low as 10 ms. This feature enables auto-focus and continuous focus for biometric applications.
