650nm 5mW Red Cross-hair Laser Diode Module Class: IIIa
This diode can be powered using a 3.3v-5v power source, great for cnc machines and other devices that have a laser guidance or targeting system. It also has a lens that allows the light to refracted into a cross-hair shape that can be adjust for focus. The cross beam has an emitting angle of 48° resulting a smaller distance when the diode is closer to the object.
These diodes are 5mW output, and have a safety label marked on them. For more information on laser safety and ratings check out the Wikipedia page

Safe use guidance - general
A laser rated as class 3R or lesser rating is low powered. It normally would not harm the eyes during a momentary exposure of less than 1/4 second. This is well within the aversion response, where a person turns away and/ or blinks to avoid bright light.
Do not deliberately look or stare into the laser beam. Laser protective eyewear is normally not necessary. A laser rated at class 3R or less is not a skin or materials burn hazard.
However, a laser rated at class 3R or lesser rating can be a distraction, glare or flashblindness hazard for pilots and drivers. NEVER aim any laser towards an aircraft or vehicle that is in motion.
ONLY ALLOW USE BY RESPONSIBLE PERSONS. This is not a toy. Children can safely use a laser rated at Class 3R or lesser rating, but only with continuous adult supervision.
