thanks! I wanted mile to be portable and handy so I can take it to the mall when shopping for a laser.
let me know if you have any questions I'll be glad to answer
Nice job on building your LPM.
I would make a few suggestions for more accurate readings....
1) the OPHIR Head should be completely out of the enclosure
to have all sides at ambient temperature equilibrium.
2) Pictures #8, #12,#16 and #17 show the Laser's beam profile
OFF the Sensor's active area center. You will get erroneous power
readings if not centered. The OPHIR heads are calibrated by OPHIR
at the exact center of the sensor.
3) In picture #9 you are WAY too close to the Sensor to get an
accurate reading. At that distance and Laser Power you are no
doubt adding radiated heat from the Laser LD and Laser head
to the actual Laser Power reading.
4) the cover was nicely designed but goes back to suggestion 1).
