Red laser modules have two wavelengths optional: 635nm and 650nm diode laser module. The visibility 635nm is higher than 650nm almost 1.5~2 times for human eyes. Because the eye safety request of laser power most prefer 635nm for better pointing visibility but higher cost. The 650nm laser module would be more cost effect. New released SMD laser module is prepared by integrating laser diode with surface mount technology. Besides of friendly SMD interface, industrial users also appreciate flexible housing structure.

Here list the standard red diode laser module.
