Lens Bending - Is it really a good thing???
Right! So I have mentioned lens bending and its effect on aberrations. Is this what I was talking about? Well, no. Obviously not. Lens designers bend rays, not lenses! Or do they? Lens element bending does have a profound effect on aberrations, and if combined properly, multiple bent lens elements can balance the aberration content. Different optical glasses such as crowns, flints, and short flints can be used in combination with element bending to provide overall balanc

So, you are a seriously technical person, but have more questions than answers when it comes to light, optics, and illumination. You’ve attended, and maybe aced, Physics 101 where you learned that light travels faster than anything else in the universe, and that lenses bend light….or at least slow it down. But when it comes to making the light form good images, or using LEDs to light something, or piping light to a display, you get more than just a little frustrated. Well,
