Metalens Arrays as a Higher Performance Solution for Microlens Arrays

Microlens arrays are traditionally used in a range of applications from CCD and CMOS imaging sensors to Shack-Hartman wavefront sensors. However, they are limited in resolution, field of view, depth of field etc… due to their conventional optical architecture.

As micro-displays have continued to increase in pixel density requirements, this conventional architecture has become more inadequate. Consequently, resulting in the need for a new kind of technology – Metalens technology. The benefits of this technology includes:

  1. Reduced track length and weight in optical systems
  2. Greater design flexibility
  3. Added functionalities
  4. Shorter focal lengths
  5. Smaller Diameters
