Characterization of an ultraviolet and a vacuum-ultraviolet irradiance meter with synchrotron radiation.
We have constructed and characterized a simple probe that is suitable for accurate measurements of irradiance in the UV to the vacuum UV spectral range. The irradiance meter consists of a PtSi detector located behind a 5-mm-diameter aperture. The probe was characterized at various wavelengths ranging from 130 to 320 mm by use of continuously tunable synchrotron radiation from the Synchrotron Ul...
متن کاملUltraviolet characterization of integrating spheres.
We have studied the performance of polytetrafluoroethylene integrating spheres in the ultraviolet (UV) region with wavelengths as short as 200 nm. Two techniques were used for this study; first, the spectral throughput of an integrating sphere irradiated by a deuterium lamp was analyzed by a monochromator. Second, a UV laser beam was directed into an integrating sphere, and spectrally dispersed...
متن کاملUltraviolet radiation and the eye.
Moderate exposure to ultraviolet radiation (UVR) from the sun is a necessary part of maintaining normal health. Ultraviolet radiation is critical for formation of VitaminD and the normal healthy growth of bones and teeth. However, excessive exposure to UVR has no health benefits and can lead to adverse consequences for the skin and eye. When the body receives excessive UVR exposure on a chronic...
متن کاملUltraviolet damage to the eye revisited: eye-sun protection factor (E-SPF®), a new ultraviolet protection label for eyewear
Ultraviolet (UV) radiation potentially damages the skin, the immune system, and structures of the eye. A useful UV sun protection for the skin has been established. Since a remarkable body of evidence shows an association between UV radiation and damage to structures of the eye, eye protection is important, but a reliable and practical tool to assess and compare the UV-protective properties of ...
متن کاملEvaluation of solar ultraviolet radiation in Zanjan city using the ultraviolet index
Background and Objective: Monitoring the amount of ultraviolet radiation from sunlight can provide a basis for assessing people's exposure, raise public awareness and warn people against this radiation. Measuring the sun's ultraviolet index over a working period is an accurate choice to achieve this goal. Materials and Methods: In this study, the amount of solar UV index in one of the outdoor ...
