Product 8/27

The LS21-BL 2.1mm monofocal lens for 1/4" and 1/3" CCD cameras, can be used to provide an extremely wide field of view. However, the picture will have an "artificially" wide field of view with a fairly severe curvarture of the video image. Unfortunately, there is NO way to provide such a wide viewing angle without this type of distortion.
This is a fixed lens with one specific field of view. There is no way to adjust the lens focal length for a dynamic viewing angle.
