Fisheye lens for UAV

Blogger's name savision
How to make your UAV have wider FOV? You should make a change of your lens of your UAV. 
I ever purchased some kinds of fisheye lens to replace the original onein our UAV, but the result is not satisfactory, the FOV isn't wide enough for me, and I found the image is blur, especially the edge. 
Last month, I purchased a 1.05mm fisheye lens  SA-010528FEB  from Fuzhou Siaon Optoelectronic Technology Co., Ltd.
The lens is very goods, with 245°x245°x245° FOV, 10MP resolution, 1/2.3" format.
I try it in my UAV. the image is better than before. If you want to make a change of your lens in UAV, you could make a try of the fisheye lens from Fuzhou Siaon.

Siaon Optoelectronic provide a series of precision optical components


Polarizing Cube Beamsplitters split randomly polarized beams into two orthogonal,linearly, polarized components-S-polarizedlight is reflected at a 90deg. Angle while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prisms.

Fuzhou Siaon Optoelectronic Technology Co., Ltd. provide Right Angle Prisms


Right angle prisms are used to deviate light by 90 degree or 180 degree. Depending on the orientation of the prisms, right angle prisms produce the inverted left handed image. Utilizing the character of critical angle, highly-efficient reflection inside is one of basic function of right angle prisms. Right angle prisms are easy to be mounted, have better stability and hardness for mechanical stress, are used in telescope and other optical system.
