I using nubm44, driver 4.5A and cylindrical lens 3x purchased by opt laser.
At 2m the beam spot is about 7mm, but it have lost power, without lens the beam bigger but much powerful.
In your video you burn at 16 feet (5m), how?
Where can I wrong?
Hello
for the M140 diode i has a good hosting (like as attachment), after several minutes, the temperature is ok.
For i want to buy this for NUBM44 Heat Sink for 12 mm Modules or you know something else?
Ok, I'm looking for e better heatsink.
What is the maximum operation temperature?
I have added a thermometer, so I can stop using when the temperature is reached and the fan still working to lowering the temperature
Yes, this is what i'll do.
Yesterday i received the diode, but i don't use before that i receive the goggle, because the actual goggle is not enough protection for that diode
OK, so if I reduce the distance at maximum 2 meters I can obtain a good compromise between power and beam diameter, with three element lens + 3X cylindrical lens, right?
