Optical Lens Design

Gogsey

What considerations would a lens maker need to take into account when designing a lens?

So on top of the chromatic aberrations, glass type and focal length, I have:

Lens Thickness
Magnification
Resolving Power
Radius of Curvature
Shape(ie cylindrical, spherical, plane)
Type(ie convex, concave, dichromatic, achromatic)
Multi-layered lens
Other types of aberrations.

Is there any of these that are not required, or any that I've missed?

Thanks

And...
1) scattering of light by the lens surfaces
2) bouncing around within the lens
3) light coming in at oblique angles and hitting the tube holding the lens(es).

#1 & #2 are influenced by the coatings.

Also if the focal plan is flat or not flat,
Where the lens is designed to be focused (infinity or closer)
The wavelengths that are to be passed through.

Probably more.

Just to add a twist on lenses; metamaterials can be used.

It doesn’t look like a lens; it looks more like a tiny set of Venetian blinds. It’s not even made of traditional lens materials such as highly polished glass or plastic. But a new generation of lenses has the potential to make big changes in radar and telecom systems by offering greater detail and a wide field of view, according to engineers from Duke University.
