Hello everybody...
Would u please help me with some qurstions...
1) On E-bay i ve seen some laser diodes with 300, 500, 1000, mW power but the prices are only a couple of dollars - no higher than 10$, but in stores or some shops relative prices for mentioned powers are too high ! So what does that mean ? why there is such desripancy ???
2) Also please have a look on some phots attached.... I was trying to run IR laser had...to track the light beam I was watching through mobile cam, when I put my cam as close as possible onto the laser diode I saw folloing little dots... what does thease dots are ? Its good its bad ?
Thanks
