I'm trying to test some solar filters....
The guys in the US have been using a Coherent 201 Power meter fitted with a LM45 thermopile head.
The local costs for such an arrangement seem to be well over $2500!!
I just need to "borrow" the power meter, and some sunshine for a few hours...
Does anyone use, or know of anyone who uses such a power meter??
