Among all visible lasers, 5mW blue laser pointer is just my favorite laser pen. Besides its bright blue laser beam emitting, i am totally attracted by its charming sapphire blue laser light emitting at night. It is only a Class IIIa laser, but not a burning laser. But its performance at night is pretty cool.
in full darkness, sapphire blue laser beam is full of the room. Besides its forma application of presentation, this
5mW blue laser pointer is making great performance in laser show, laser display, lab experiment. Laser amateurs can just enjoy the fun freely from this cool laser.
