Specifications for Fisheye lens

 

360 degrees Circular Fisheye lens Compatible to all Brand projectors High quality low cost

A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image;
Fisheye lenses achieve extremely wide angles of view by forgoing producing images with straight lines of perspective (rectilinear images),
opting instead for a special mapping (for example: equisolid angle), which gives images a characteristic convex non-rectilinear appearance.

Applications for Fisheye lens :

*Some planetariums use a form of fisheye lens to project a two-dimensional film image of the night sky onto the interior of a dome. The Navitar HemiStar 6.75 mm Fisheye lens is used for dome projection.

*Flight simulators and visual combat simulators use fisheye lenses like the Navitar HemiStar in order to create an immersive environment for pilots, air traffic controllers, or military personnel to train in.
Similarly, the IMAX Dome (previously 'OMNIMAX') motion-picture format involves

*Scientists and resource managers (e.g., biologists, foresters, and meteorologists) use fisheye lenses for hemispherical photography to calculate plant canopy indices and near-ground solar radiation. Applications include evaluation of forest health, characterization of monarch butterfly winter roosting sites, and management of vineyards.

*Photographers and videographers use fisheye lenses so they can get the camera as close as possible for action shots whilst also capturing context, for example in skateboarding to focus on the board and still retain an image of the skater.
