2. First of all-
• This was put together last minute
• We couldn’t get very much information
• I hope you enjoy it at least a tiny bit
• AND OMG ISNT THE BACKGROUND AMAZING!
3. What is a UV telescope?
• An ultraviolet telescope is a telescope used to
examine the ultraviolet portion of the
electromagnetic spectrum, between the
portion seen as visible light and the portion
occupied by X-rays.
4. How does it work?
• 1. Usually they are reflectors to keep glass out
of the light path as much as possible (as
opposed to refractors).
2. They need to be at high altitudes or in
space (there have been UV telescopes carried
by high altitude balloons, modified aircraft,
and of course, by satellites.
3. They need a detector array sensitive to UV.
Not uncommon these days.
5. Why do we use it?
• A UV telescope is used to examine the
ultraviolet portion of the electromagnetic
spectrum, between the portion seen as visible
light and the portion occupied by X-rays.
6. What do they need to function?
• They function the same way that normal
telescopes do:
They usually they are reflectors to keep glass
out of the light path as much as possible
(unlike refractors). Ultraviolet Telescopes need
to be at high altitudes or in space. UV
telescopes have been carried by high altitude
balloons, modified aircrafts, and by satellites!
UV telescopes need a detector array sensitive
to Ultraviolet light.
7. Pros and Cons
• The human eye is very limited to the light
wave lengths that it can see.
• These two types of telescopes allow us to see
beyond the limits of our eyeballs.
8. Examples of that type
• IUE (International Ultraviolet Explorer)
telescope
• EUVE (Extreme Ultraviolet Explorer) satellite
• HST (Hubble Space Telescope)
• FUSE (Far Ultraviolet Spectroscopic Explorer)
• UIT (Ultraviolet Imaging Telescope)
