Rear Focal Plane of A Lenticular Network
The focal length of the lens is calculated from the lensmaker's equation, which in this case simplifies to:
- ,
where is the focal length of the lens.
The back focal plane is located at a distance from the back of the lens:
A negative BFD indicates that the focal plane lies inside the lens.
In most cases, lenticular lenses are designed to have the rear focal plane coincide with the back plane of the lens. The condition for this coincidence is, or
This equation imposes a relation between the lens thickness and its radius of curvature .
