This is a 488nm laser pointer with a nice brass host, activated by a side button. The beam is very bright at night and easily visible indoors, even during the day! Our 488nm pointers are built to feel nice and heavy in your hand - the build quality is MUCH better than your typical pointer. Beam specs are excellent - with good divergence, and with less of the annoying box reflection compared to other green and blue laser diodes. These can be powered with either 2xAAA batteries or 1x10440 and a dummy battery. Batteries should be inserted with the positive side facing the front of the laser!
