I want to ship (at my expense both ways) a solar panel and a voltmeter; which I use as non-linear way to measure laser power, so they can find out how accurate it is for me.
I've measured four lasers with it by connecting the voltmeter to the solar panel to measure its output voltage while lasers are pointed at it.
These are the results:
1. My 100mV green measures ~115mV-135mV then drops to ~108mV.
2. My 75mW green CNI measured ~66mV-103mV.
3. My 200mW (rated with 1.5Vs) red measures, ~180mV with 1.2Vs
4. And someone else's 300mW 980nm "lab" laser measures 330mV-332mV
I need the person I send to have a proper and accurate laser measuring device, lasers at different wavelengths, and a high post count (for credibility). I'm willing to pay ~$5 for this plus the shipping charges.
Please respond if interested.
