About micro lens arrays

A micro lens arrays (MLA) is an optical element in which multiple micro lenses are arranged and arrayed to achieve specific optical functions by adjusting their shapes, focal lengths, etc. They significantly improve the integration and performance of optical devices. Its main functions are light collection and diffusion, and it is used in a variety of fields and applications as described below.

Applications

  • CCD/CMOS image sensor
  • Optical communication equipment (collimation, coupling lens, etc.), optical interfaces, CPO (co-packaged optics)
  • Digital cameras
  • High brightness LED, organic LED

AGC's micro lens arrays

Fearures

  • Lenses with submicron level accuracy can be formed.
  • High accurate and various lens intervals (array pitch) can be arranged.
  • Not only single-sided arrays but also double-sided arrays can be manufactured.
  • Antireflection coating can be applied by surface coating.
  • Micro lens array with a lens pitch of several ten μm can be formed.
  • Supports customized design with function addition according to applications.
    • ・Gapless
    • ・Lens space light shielding
    • ・Square lens
