In standard experiment with prism, you can create a rainbow from a thin beam of white light. Is it possible to design a lens that will create a rainbow from a broad beam? Even if it is only at a fixed distance from the lens?

A "Rainbow from broad beam" is an optical phenomenon that occurs when light is refracted and dispersed by water droplets in the atmosphere, creating a spectrum of colors visible to the human eye.
A "Rainbow from broad beam" forms when sunlight passes through water droplets in the air, causing the light to be refracted and dispersed into its component colors. The water droplets act like tiny prisms, separating the white light into its visible spectrum.
The colors of a "Rainbow from broad beam" are red, orange, yellow, green, blue, indigo, and violet. These are the same colors that make up the visible spectrum of light.
No, a "Rainbow from broad beam" can only be seen from a specific angle. The angle between the observer, the sunlight, and the water droplets must be around 42 degrees for a rainbow to be visible.
No, the shape and size of a "Rainbow from broad beam" can vary depending on the size and shape of the water droplets in the air, as well as the angle at which the light is hitting the droplets. They can also appear as full circles in certain circumstances, such as when viewed from an airplane.
