Note:
The modules are tested and the output power are measured by laser power meter before sending out.
Please don’t compare the power of this one with a none-measured laser.
If you doubt the output, please have the laser you recieved checked by laser power meter.
If there is any problem, please feel free to contact us. We will solve the problem asap.
Comparing with the 638nm with the 650nm laser, the 638nm is much more brighter than the 650nm laser at the same output. the 638nm 150mw is more brighter than 650nm 200mw. but the heat the 638nm is 80% of the 650nm one.
