Basic information you should know about Fisheye Lens

2018-08-04 16:14:06 216

Fisheye lens is a short focal length (f = 6-16mm) camera lens with wide field of view (FOV of approximately 180°, could even be 270°). Front of the lens looks like a bulging Fisheye which it’s so called Fisheye lens. It’s a super- wide-angle imaging lens that can capture the image that ordinary lens incapable to capture.

Most commonly used lens are design to project straight line in every direction, while these lens has image distortion exists only around the screen and it’s relatively mild. However, distortion is an inherent characteristic for Fisheye lens. The image capture by Fisheye lens will have exaggerated distortion on the edges that is shown in an arc-shape. Unlike the ultra-wide-angle lens that loses light on all four corners, the main feature of the Fisheye lens is allowing screen brightness uniformity.

 

 

Based on the above characteristics, Fisheye lens can be used in many fields:

1. Cinema

2. Meteorological

3. Planetarium

4. Testing Technology

5. Medical

6. Fire Monitoring

7. Security Surveillance: Fisheye has steady focus. Simply put it in a place that needs to be monitored, and it does not need to move or rotate. Information can be captured from any angles in a hidden place.

8. Alert Applications: Fisheye lens can be putted at major intersections, terminals, border and coastal defense stations. The advantage of Fisheye lens is that it can work 24/7 by itself.
