Thermal Visible X-Ray fluorescent tube
Truly multispectral!
Here is a 12V fluorescent light seen in thermal infrared, visible and X-Ray. (In the X-Ray shot the light wasn't operating, hence the lack of crocodile clips connecting it to a power supply).
The thermal image was made using my Therm-App thermal imager with 13mm f/1 lens and ThermApp Plus software, the visible with a Nikon D700 with 28-300mm f/3.5-5.6 and the X-Ray image with my Scanmax 20 X-Ray mail scanner. Images were post-processed using AutoStakkert! and Paint Shop Pro.
The thermal range is 14-7µm, visible is about 700-400nm and the X-Ray image is at about 20pm (50-70keV - best guess). That's a very wide spectral range in anyone's money.
Comments are warmly invited.
