Title: Compact Luminescent Lens Design for Laparoscopes

Invention: University of Arizona researchers have developed a more uniform illumination system for better medical images. The system directs outgoing rays from the fiber bundle to provide more uniform illumination, even with extended non-lambertian sources.

Background: Aspherical lens are typically used to correct spherical and other aberrations. They are inexpensive and fabricating them into an array can improve the image.

Applications:

  • Fiber bundle based illumination and imaging
  • Laparoscopy

Advantages:

  • Brightness is uniform across the object of interest
  • Inexpensive to fabricate
