2. Far Ultraviolet Camera/Spectrograph - Wikipedia

   en.wikipedia.org/wiki/Far_Ultraviolet_Camera/...

   A second spare telescope was slightly modified and later flown on Skylab 4. It was given an aluminum (Al) and magnesium fluoride (MgF 2) mirror rather than rhenium. It was mounted on Skylab's Apollo Telescope Mount for usage in orbit. [1] Among the many images and spectra that it took, it was used to study ultraviolet emission from Comet ...

   These Photons can be seen by the naked eye, can be imaged with a camera or analysed with an UV/VIS spectrometer. To distinguish between excitation source and emitted signal, a bandwidth limited source (Light-emitting diode in UV regime) and a longpass filter can be used. [8] Luminophores are originally not present in a PV module.

4. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   In a light-emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called "electroluminescence". The wavelength of the light depends on the energy band gap of the semiconductors used. Since these materials have a high index of refraction, design features of ...

5. Excimer lamp - Wikipedia

   en.wikipedia.org/wiki/Excimer_lamp

   Excimer lamps are quasimonochromatic light sources operating over a wide range of wavelengths in the ultraviolet (UV) and vacuum ultraviolet (VUV) spectral regions. Operation of an excimer lamp is based on the formation of excited dimers (), which spontaneously transiting from the excited state to the ground state result in the emission of UV photons.

6. Ultraviolet - Wikipedia

   A portrait taken using only UV light between the wavelengths of 335 and 365 nanometers. Photographic film responds to ultraviolet radiation but the glass lenses of cameras usually block radiation shorter than 350 nm. Slightly yellow UV-blocking filters are often used for outdoor photography to prevent unwanted bluing and overexposure by UV rays.

8. Photolithography - Wikipedia

   en.wikipedia.org/wiki/Photolithography

   Theoretically, an alternative light source for photolithography, especially if and when wavelengths continue to decrease to extreme UV or X-ray, is the free-electron laser (or one might say xaser for an X-ray device). Free-electron lasers can produce high quality beams at arbitrary wavelengths.
