High-output, low-loss laser design technique with wider near-ultraviolet laser optical waveguide and optimized light loss control.
Like a prism, STIS separated light into its component colors, and it then recorded the intensity of wavelengths ranging from the near-ultraviolet to the near-infrared.
Observations in visible light during the early 1970s of a dozen eclipses of Io by teams of astronomers at Mauna Kea and Cerro Tololo observatories failed to detect any anomalous post-eclipse brightenings, but in 1971 photometric measurements conducted independently at Kitt Peak and Table Mountain observatories convincingly recorded a post-eclipse brightening that was more pronounced in the near-ultraviolet region of the spectrum at wavelengths of 350 to 400 nanometers than it was in visible light.
X-shooter is one of the most sensitive spectrographs on Earth and can observe light from the near-ultraviolet to the near-infrared in one shot.
Images of the core of NGC 4150, taken in near-ultraviolet light with the sharp-eyed Wide Field Camera 3 (WFC3), reveal streamers of dust and gas and clumps of young, blue stars that are significantly less than a billion years old.
Irradiation of the partially built oligomer with near-ultraviolet wavelengths (mainly 365 nm) deprotects the terminal hydroxyl group, and the use of appropriate masks allows for control of the sequence of the probe and the size of the features.
One way to achieve this effect is to use an Earth-orbiting satellite, such as ACRIM, that monitors the total amount of radiation that the sun emits at wavelengths ranging from the near-ultraviolet to the near-infrared.
