A novel imager uses a tunable fluidic lens and fixed lenses for versatile camera and microscope functions. This compact device offers an ultrawide autofocusing range and high-resolution imaging capabilities.

Area of Science:

  • Optics and Photonics
  • Microscopy and Imaging Technologies

Background:

  • Traditional imaging systems often face limitations in terms of size, versatility, and autofocusing range.
  • Miniaturization of optical devices is a key challenge in developing portable and high-performance imaging solutions.

Purpose of the Study:

  • To develop a highly versatile and compact imager.
  • To integrate a tunable fluidic lens with fixed lenses for broad imaging applications.
  • To achieve both regular camera functionality with ultrawide autofocus and microscopic imaging capabilities.

Main Methods:

  • The imager was constructed using a tunable fluidic lens combined with three fixed lenses.
  • The device was designed for a small volume (< 1 cm³) and a short total track length (12.5 cm).
  • Performance was evaluated for both camera and microscope modes.
