Lens Design: Considerations for Lens Maker

AI Thread Summary
Lens makers must consider various factors when designing lenses, including chromatic aberrations, glass type, focal length, lens thickness, magnification, and resolving power. Additionally, the radius of curvature, lens shape (cylindrical, spherical, or plane), and type (convex, concave, dichromatic, or achromatic) play crucial roles. Coatings are important for minimizing light scattering and reflections, while the design must account for the focal plane and the wavelengths intended to pass through. Emerging technologies, such as metamaterials, offer innovative alternatives to traditional lens designs, potentially enhancing performance in radar and telecommunications. Overall, a comprehensive understanding of these elements is essential for effective lens design.

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

Coatings
 
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.

Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
