I'm interested in these red lasers on ebay:
eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices
650nm 50mW Industrial Red Laser Line Module Power Plug - eBay (item 180521164574 end time Oct-13-10 09:02:48 PDT)
But I noticed they project lines, not the standard "dot." Is this easy to modify? I thought to get a line you needed to put a filter or different lens in front of the laser.
Also, do you think these are designed for 100% duty cycle? Many of the auctions mention that the laser needs cooling, but these do not...
Thanks!
