This is a replacement sensor for your JeVois camera. It features a fisheye lens with a wider field of view than the original: 120 degrees horizontal. Because of the very wide field of view, straight lines in the world are distorted and appear as curved in the image. This is common to all wide-angle fisheye lenses and is known as barrel distortion. JeVois provides an algorithm for the correction of barrel distortion, which runs on the GPU inside JeVois (see http://jevois.org/moddoc/DemoGPU/modinfo.html ).
Note that the lens has been adjusted at the factory for a focusing distance of 30cm to infinity. In addition, we asked the factory to NOT glue the lens once focused. So, you will be able to easily change focus by simply turning the lens. Once you have found your optimal setting, you should fix the lens using a small drop of glue, paint, nail polish, etc on the thread (as was done with the standard lens pre-installed in JeVois).
Purchase this if you are interested in a wider field of view than the original lens, with the awareness that you will likely need to spend some CPU or GPU resources de-warping the barrel distortions. Note how objects in front of JeVois will appear smaller with this lens compared to the original lens. But in exchange, you will see much more broadly to the sides of the optical axis.

Note: opening the case of your JeVois camera voids your warranty. So please proceed with caution.
