What is the temperature of a laser beam ?

Hehe.. perhaps you can destroy an IR thermometer by shining a laser into it, doesnt seem that far fetched really.

It depends on the laser. IR thermometers have a window/lens that blocks visible and near IR light so at best you'll crack the window from thermal shock or melt the plastic holding it in place.

Makes sense, otherwise you'd be getting bad readings from other sources of light.


I had contemplated making a laser thermometer myself, DIY style as well as a laser rangefinder...

I found that there's quite a bit of tech involved in making them. Very very high speed, that capacitive reactance and resonance and a lot of other things just start to really make it difficult.
