What did you use to coat your Peltier ? *What kinds of results did you have ?[/quote]

Well since you asked and since this was rough and dirty test, I used a very special fast drying black ink -------> a sharpie. *;D *:

The benefits: *
-Very thin means a fairly good heat transfer to the peltier
-It's fast and redily available
-You can re-apply at will

The drawbacks:
-have no idea of the reflection/absorption for different wavelengths
-not sure about durability
-longevity
-susceptibility to damage from the beam (will it last long enough to get a stable reading???)

As far as results, it didn't record any results but I recall that the Glowtorch one generated about 70mV with my GB LD (@190mA) close behind (~60mV) and my DX 30 well behind those. I used one of the small double-stacked TECs.

This is an interesting idea, I just recently got a small pelt and if this pans out I would love to pick up another and use it in such a manner. I'd even be willing to set it all up and send it to someone that actually has a meter to test with to find out the drop ratio so I could figure out my lasers power as I test with them.


As far as the surface, I suggest a thin piece of black anodized aluminum, the anodizing should absorb alot of the power with little reflection and wouldn't be as suseptible to burning like the sharpie would.
