Flsheye Lens f4.9mm F1.7 FOV 180deg WaveLength486-656nm YY4917
A fisheye is an extremely wide-angle, very-short-focal-length lens with a field near/equal to 180°. The source describes its front element as having a short diameter and a parabolic protrusion resembling a fish eye. Images either fill the frame or form a circle; both show strong distortion and perspective convergence, often used for special effects. Huge coverage suits surveillance, satellite positioning, robot navigation, miniature intelligent systems and engineering surveys. Full-space coverage and continuous real-time acquisition also suit defense information-gathering needs. Fisheyes project onto domes/irregular screens, including full spheres, hemispheres and spherical caps in museums/exhibitions. Common dome arrangements use one projector near the center, two at opposite poles or multiple blended projectors, often four, five or more.
