mot of the information on lenses is geared towards making a tiny spot, for burning stuff, or making a cool laser beam at night...
I have ben seeing "flashlight" lasers around... but they are expensive...
I just thought it would be "neat" to have a little "flashlight" that had an adjustable beam size (spot-ish... up to, i dont know, a coupel of degrees cone would be good)
I have been seeing them in green (the commercial ones), but really, red would be kinda cool too.
i CANT be the only guy here, that ever wanted to make a "flashlight laser" since they sell the dang things... when i think about it, it just seems a matter of getting a host module that has the "proper" lens...
most "specs" will brag up how TIGHT their lens can take the beam down... no one really "brags" that they can go up to a couple degrees spread...
what on a lens would indicate it had this ability?
(I figured if i went "uncoated" glass... when i built a different color one next time, it would just be a matter of picking a different driver)
==================================================
is there a particular "generic" module host, that one could use for this?
(i usually think in terms of to-18)
===================================================
i mean, how COOL would it be, to have a little green or red flashlight... and you can POINT up on the hill across the river, at what you are talking about...lol
