It's fine, I'll keep it. I would recommend checking the output of other lasers you meter against the pics on DTR's site, whenever you're using the same diode. If your numbers consistently show higher mW output than his pics at the same current, and with the same lens type, there's a good chance your LPM is inaccurate. I also recommend getting copper modules for your diodes.Maybe your LPM is wrong, or my one is wrong!
but I see the sensor distance you measure is far away from me!
I have to measure at such a close distance because my sensor is small, if far away the laser will cover the sensor, so it will deviate power!
You asked me to set 1.8A, I did!
All my parameters are based on LPM!
If you are not satisfied with the product, please send it back to me then I will refund you! thanks very much!
