Blue and Yellow Laser Pointers

[Kiessling]

Isn't 5mW the upper legal limit of those things outside your own home?

P.S.: I always thought they are called "pointers" for exactly that reason. At least that's what I use mine for ... /ubbthreads/images/graemlins/smile.gif

Edinburgh instruments is the other distribution outlet for httP://www.cnilaser.com

I'm not sure how much that yellow cost (I guess about £180/£200 ish) as I don't have Adobe reader lol but do you know how much they want for the CNI PGL3?

£490!

 

[Bond007]

Duh, I've just noticed the price of the yellow is at the top of the page!

 

[laserman2000]

Why are most yellow laser pointers either <1mw, or <2mw?
I want a 5mw or more!

 

[laserman2000]

Is it possible to change the crystal in a green laser and turn it blue or yellow. I believe it might work with yellow, what craystals would you need?

i've used a red pointer 10 years ago in my classroom. i was a 5th grade classroom teacher. i occasionally use my red pointer, but not in this school. i just got a green laser pen, i'll be using this real soon, to point out thing in the classroom.

If they were easily availiable, would you buy a blue?

 

[Bond007]

I certainly would like one if they were "easily available", but then the same could be said for an Aston Martin V12 Vanquish.

If I win the lottery, I'll certainly own a nice bluey then /ubbthreads/images/graemlins/grin.gif

 

[laserman2000]

I'd prefer the car!

If you won the lottery you wouldn't have to choose

 

[Bond007]

Looking back on that last post of mine, I might be able to afford the blue laser, the car AND a few extra brain cells /ubbthreads/images/graemlins/smile.gif
