50mW 532nm Green Laser Module (3V 11.9mm)
Involvement:Expert (understands the inner workings) - Ownership:more than 1 month
Pros:Ready to attach to power source. Bright enough to see beam in most lighting conditions. Small enough to fit into many types of enclosures.
Cons:If you value your eyes, get some goggles that cover 532, 808 and 1064nm... or use a piece of heat absorbing glass in front of the laser as a filter.
OtherThoughts:Limited focusing range, leads need to be re-soldered right out of the package. Not truly 50mW output. 50mW Input current would be a more precise description.
Easy to use/setup, can be focused, very bright, some burning ability. Great for doing F/X, general experimentation, astronomy.
Bottomline:Limited focusing range, leads need to be re-soldered right out of the package. Not truly 50mW output. 50mW Input current would be a more precise description.
