Laser Head Copper Pointer Sight 5V

A focused red laser dot in a small copper barrel, running directly from 5V with no driver circuit needed. Pairs with a laser receiver module to make a beam-break detector for alarms, counters and gates, and is also used for pointing, alignment and distance-trigger projects. The lens screws in and out to focus the dot at your working distance. Standard laser safety applies: never aim it at eyes or reflective surfaces. Runs directly from 5V, no driver circuit needed; Adjustable focus for different working distances; Copper housing dissipates heat well; Pairs with laser receiver modules for beam-break sensing
