Sensitive UV Detector Ignores Visible Light
techmaven writes: "Scientists at Northwestern University have
developed a new device that detects ultraviolet
light and at the same time ignores visible light. The researchers said that the new detector
could lead to a UV light detector approximately 10 times more sensitive than those now on
the Hubble Space Telescope, allowing astronomers to observe important objects throughout
the universe for the first time."
A filter. Well done chaps.
