If the Balmer series describes the emission lines produced when hydron atoms are electrically excited when subjected to visible light, the eye can visibly see these lines. How did Lyman do do for the ultraviolet spectrum, how did he observe emission lines for the ultraviolet spectrum and how did paschen do it for the infrared spectrum?

Scientists use other instruments to measure quantities besides the human eye, you know! How do you think doctors read x-rays? With super-powers? No, a machine does it for them, then creates an image for the doctor to see. The image is a visible light representation of the x-rays

I know that!...I want to know how they did it back then. How did Lyman and Paschen do it and what was there experimental setup.
 
One type of detector could be photographic plates.I'm assuming that back in the day of Lyman and Paschen there were photographic emulsions sensitive to I.R as well as to light and emulsions sensitive to U.V, X rays and gamma rays.I think the higher the frequency to be detected the greater the silver content in the emulsion.

I too was thinking something like this. It would be great if someone could confirm it.
