The FJI series is a fisheye lens with an ultra-wide angle of view of 180°.

In conventional surveillance, multiple camera systems were required to cover all directions centered on the camera, but this 180° angle of view lens can cover with one unit. The lightweight and compact design makes it possible to monitor applications in confined spaces. In addition, since the image around the 180° is extremely clear, it can be used in combination with an image processing device to detect scratches on the inner wall of pipes, etc.

Usage

  • Various security
  • medical nursing monitor
  • Buckeye for automobiles, etc.
  • Internal inspection of pipes, etc.
  • Inner surface inspection of various containers
  • others

Optical design method

This fisheye lens is designed with the equidistant projection method (EF-theta lens).
Equidistant projection y'=fθ (y': image height f: focal length θ: half angle of view)
