Hi,
I would like a cyan (465–495nm-ish) laser for casual use (i.e., actually pointing with it in public settings where people won't be wearing safety googles)—necessitating an output power of 5mW. Whereas, the (few) cyan laser products that exist are either expensive (example: Laserglow...
Hi,
My name is Ian. I'm a computer science / optics Ph.D student.
My main work is on figuring out how to take geometric descriptions of things and turn them into photorealistic pictures. Most people use approximations to do this, but I've found that being a little more careful with accurately...
How to solve questions of the form "Is (*)mW at (*)nm brighter than (*)mW at (*)nm?"
Hi,
I've seen a lot of questions of the form: "Is (*)mW at (*)nm brighter than (*)mW at (*)nm?" (ex 1, 2, 3, 4, 5, 6, etc.).
The first thing to know about is the luminosity function, which basically says how...
