lenses for lasers insted of just seperating the colors

[Mr. Universe]

Instead of just separating the colors you should be able to increase or decrease the size of the beam like a microscope(Makes tiny light big) and a telescope(Makes big light tiny) while retaining the original color with a lens . I was looking forward to making my cars have actual head lights instead of tracers, but all i get are rainbows!

In actuality: In lens telescopes, the colors DO get seperated (slightly).
You should stick to parabolic reflectors.

I just tried it and it just reflects a straight line back.

That's also how it works in real life.
In real life, the light bulb radiates light, meaning all the light spreads out from the start.
