Test Results of maXYZmodules 150mW RED
Here are some test results from my friend kevin from "Junktronix "
Who graciously tested of one of our modules for us...
This is a typical 150 RED.. nothing special , just a pick out of the pile..
Enjoy ...As we do...
As quoted from Kevin below:
Had some time to play in the lab today and here's what I found. The first 5 pictures are of my OSA:
#1 - module running at 9V, after 20 minutes warmup. Lasercheck reads 141mW @ 661nm
#2 - module running at about 6.2V, lasercheck reads 77mW @ 659nm (Diode running SINGLE MODE)
#3 - module at 9V, cooled to 18C, lasercheck reads 143mW @ 660nm
#4 - module at 9V, cooled to 14C, lasercheck reads 147mW @ 659nm
#5 - 2mW hene for reference. Notice much narrower scan width (1nm across entire screen versus 10nm for diode data)
The next 3 are from my beam profiler
#1 - module running at 9V
#2 - 3D view of above
#3 - 2mW hene (I'm having problems setting the gain so this is not the best data, but shows that the beam is round and gaussian)
My 30 second analysis: the diode is single mode when run near it's rated power, but becomes multimode when driven harder.
