so look, you're going to need either a diffraction grating or a prism made out of a UV transparent material, and youre going to need a phosphor. you wont be able to have a digital readout but you will be able to physically measure the wavelength of whatever source youre using. and there are many obvious ways to improve the accuracy of these setups

all of the gaslight is truly bewildering, who are these human beings that think air actually is opaque to high frequency photons? how the fuck do all you retards think xrays are possible? OP didnt say they were trying to fucking measure sources from fucking outer space
