Being made with an import 635nm red laser diode within 5mW to 100mW, not the same as a simple red laser pointer only used for temporary positioning works, this pro red cross laser alignment is always trying to make continuous red laser beam and red cross line projection from beam aperture. It is allowing quite easy screw of adjustable focus optic lens, the most concentrated red laser light is just converting highly fine red cross line source in distance. In occasion that it is operating with high attention to laser safety issue and wearing correct laser safety goggles, high power red cross laser makes safe and quick measurement in all application fields perfectly.
