Chris, by expander lens do you mean a collimator lens that is further away giving the divergence of a BE? I see you got more of these OPSL laser modules.

Very nicely done. I wasn't planning on watching your entire video, but it was so instructive I couldn't help myself. Thanks.
Heater voltage is 1.5V-2.0V. Try 3.0V at your own risk.
Not all of them have the output expander lens, mine didn't but another user on Discord did have one on his.
I got 90mW - 110mW of power for different units at spec. current max (480mA, 23°C, Heater = current optimized at ~60mA).
I was dubious that the heater could be controlled by setting the current for a standard amount instead of measuring the temperature and setting it that way.
