Performance is Ok for this price, I got what I expected. - Can be focused within app 1mm, but do not expect a perfect circular dot, - Visual brightness seems to be even less than a keychain type laser marker, but power is OK when you try it on dark material. - Power is just enough to burn a non reflective black (matte dark color) paper, wood or plastic, it takes 5-10 seconds to see smoke or discolorizution. I focused it to a distance of 8-10cm. - Connections of driver module marked on the base of the plastic support of the driver module (sorry, this may be obvious for others, but it took some time for me to find out it.)

  • inverse2k1 Hello Mr. Selcuk,actually, based on your description, it looks like your module is quite a bit underpowered compared to the specifications. At 500mW any kind of black plastic should smoke almost instantly. Also, if the focus is correct you should be able to see a bright yellow spot of smoldering very hot plastic.What you describe is what you should expect from about 50mW of power, so ten times less than what is declared. I suspect your power supply is either not calibrated or the diode is bad
