I thought I had considered that when I mentioned splicing the cables together. By having each cable feed into one main cable of the same diameter, you end up with a smaller surface area where the radiation exits the cable. Wouldn't that decrease the radiation that entered the box?

Since radiation depends on surface area, I assumed that the cables would not radiate inward, is this incorrect?

I'm hoping I'm in the right forum for this, but here's my question. Optical cable can guide radiation to a point, which is the basic of my thoughts. Say you had an insulated box. On the inside of this box, is a liter of water in the shape of a cube, giving it a surface area of .06m^2. From the...

In my understanding of it, spherical aberration is caused by the spherical curvature, and non-spherical curves in lenses don't show it. Even without the spherical aberration though, it still seems like the focal point of the lens would be skewed by the variously angled rays of light refracting...

But a plano-convex lens does have a focal point, which is where I'm confused.

Then in the case of a plano convex lense, wouldn't the light refract differently upon exit than upon exit, causing a very blurred focal point?

Well in that diagram it shows the light refracting twice, but the second refraction refracts the light inward, instead of outward.

Not quite, I'm asking why, in lens diagrams, the rays are only seeming to refract once, and not straighten out some after the light exits the lens.

Right, that's exactly what I'm saying. My main question though, is why does that not happen to a degree in one of the standard basic lenses, because in a biconvex lens, the light does not leave the lens at an angle somewhat unrelated to the angle it entered at, because the light would be bent...

No, because light would not need to hit at a specific point for the concentration to occur, the light would enter at the same angle it left at, meaning it would be concentrated, but moving linearly. And doesn't the point in which the image appears to be coming from apply mainly to diverging...

In a standard biconvex lens, yes, but not in a plano-convex or a negative meniscus lens, which still have a focal point that seems to disregard both refractions. And I don't believe it's true that you must have a focal point to concentrate light. You would need a focal line(which could probably...

I've been doing some calculations on lenses, and I'm a little confused about some of the diagrams I've seen. Looking at a ray diagrams, I see the light passing through the lens, at one angle, and then converging on a focal point from there. Using snells law to calculate refraction through the...
