  2. Ultraviolet index - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet_index

    Sunburn effect (as measured by the UV index) is the product of the sunlight power spectrum (radiation intensity) and the erythemal action spectrum (skin sensitivity) across the range of UV wavelengths. [9] [10] The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the Earth's surface.

    Sunburn effect (as measured by the UV index) is the product of the sunlight spectrum (radiation intensity) and the erythemal action spectrum (skin sensitivity) across the range of UV wavelengths. Sunburn production per milliwatt of radiation intensity is increased by nearly a factor of 100 between the near UVB wavelengths of 315–295 nm.

  5. Tanning lamp - Wikipedia

    en.wikipedia.org/wiki/Tanning_lamp

    The amount of UV that is generated from a low-pressure lamp is highly dependent on the temperature in the tanning unit. As a rule, tanning lamps produce the highest amount of ultraviolet light when this temperature is between 90 and 110 °F (32 and 43 °C). As the temperature moves away from this range, the amount of UV produced is reduced.

  6. Coincidence rangefinder - Wikipedia

    en.wikipedia.org/wiki/Coincidence_rangefinder

    The degree of rotation of the compensator determines the range to the target by simple triangulation. [1] Coincidence rangefinders made by Barr and Stroud used two eyepieces, and may be confused with stereoscopic units. The second eyepiece showed the operator a range scale so the user could range and read the range scale simultaneously. [2] [3]

  7. Ecamsule - Wikipedia

    en.wikipedia.org/wiki/Ecamsule

    The UVB range is 280 to 320 nanometers, and the UVA range is 320 to 400. Ecamsule protects against UV wavelengths in the 290–400 nanometer range, with peak protection at 345 nm. [ 4 ] [ 5 ] Because ecamsule does not cover the entire UV spectrum, it should be combined with other active sunscreen agents to ensure broad-spectrum UV protection.

  9. Ultraviolet–visible spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet–visible...

    Mettler Toledo developed a single beam array spectrophotometer that allows fast and accurate measurements over the UV-Vis range. The light source consists of a Xenon flash lamp for the ultraviolet (UV) as well as for the visible (VIS) and near-infrared wavelength regions covering a spectral range from 190 up to 1100 nm.
