Today another proof that reflected UV photography is doable at UV-B and UV-C using several special, up to NIR blocked, narrowband filters and a very different UV camera, an amplified 190-650nm MCP equipped video camera. Lens used was a CERCO f1.8/45mm quartz flourite lens. Light source was a candle flame.

This reveals, that the deeper one looks into UV, the area where the candle flame emits that UV moves from the top of the flame down to the sides of the flame. Pretty amazing how sensitive this type of camera is, as the needed amplification was still just in the lower 30% of the total available range.
I have a newer system HERE with a normal camera attached to the MCP amplification device.
I have previously written more about combustion and UV HERE.
Btw. Michael Faraday has in 1848 given six famous lectures about the chemical history of the candle, which may be read about HERE
Stay tuned, more will follow on that fascinating subject...
