I'm looking to buy a 520nm laser diode pen style pointer powered by common batteries like AAA or AA. Do they exist?
The reason is I plan to use this once in a while at star parties and I only turn them on very briefly to avoid too much disruptions. So there is no need for long duration lithium rechargeable batteries. Rather I prefer the convenience of AAA or AA which I have alot of at home.
I see laserland has a 520nm laser pointer on ebay for $24 but it uses 16340 batteries.
o-like has a $99 120mW for $99 and uses 18650.
I already have DPSS green pointers using AAA. They work fine but I just want to have a laser diode version.
Any suggestions?
