Yea, it makes a good comparator and can tell you % IR.
I needed one for draft finding since we've been doing outside remodeling.
Just make sure the "target" blocks the opening to the sensor.
If you had a piece of aluminum sheet stock .010 or a soda can cutout painted black the worst that 445 could do is fry the paint.
Just used as a comparator, I don't see the need for keeping the target size. It will take longer to heat and low mw like that 5mw red may not register for a long time or at all.
With the 3.13 multiplier, the 5mw 660nm raised the target 1*.
I have done some with 3 of my 532nm pointers and it's easy to see which one has the best output. 405nm pointers too. I was amazed the 532nm's were so high in IR. I expected abt 30%.
Like I said it was fun and informative.
If you have no LPM at all it can tell you quite a bit.
Someone with a calibrated LPM and a low and high mw laser would be interesting to see how it fairs out.
My guess is you'll have a different multiplier do to all the variances to hit the on spot output number.

With 1W of 445nm that's gonna be hot. :gun: :eg: Sounds like you might need header or barbecue paint and then you may still need that larger target I mentioned so you can defocus the beam enough to not fry it. The magic 3.13 number would need recalculated though if the target size is changed. If you have a real LPM, easy enough to create the number for you target.
