There are no lenses on the HST. The instrument is a reflector (= mirror). The amazing images are produced by long exposures (over hours) and observing in various spectral ranges (colors) separately.
No, it isn't. The Hubble Space Telescope is a reflector. It has a primary mirror, and not a primary lens.
A flaw in the lens
The main difference between Hubble Space Telescopes and other telescopes is the fact that the Hubble is placed in outer space where it can observe without the distortion of the Earth's atmosphere.
Yes, the Hubble Space Telescope was launched with a flawed primary mirror rather than a missing lens. The mirror had a manufacturing error that affected its shape, leading to blurred images initially. This was rectified through a repair mission in 1993, successfully improving the telescope's performance.
the hubble telescope is a refracting telescope and it is the biggest one because the refracting telescope can only have a certain range of size for the glass lens because it can only hang on the telescope and it is aproximently 5 meters big the lens. hope it helped
The Hubble Space Telescope is a reflector, so its objective is not a big-moose lens at the front;it's a big mirror in the back.The diameter of the objective mirror is 2.4 meters(7.87 feet), (94.5 inches).
The Hubble telescope was a basic reflector telescope with a 94.5 ft mirror. The Hubble collects light though its open end, the primary mirror reflects the light to a secondary mirror that then reflects the light through a hole in the primary mirror to a focal point of the instruments or eyes of the Hubble.
The Hubble Space Telescope, or HST, or just the "Hubble" for most folks, is a Ritchey-Chrétien reflector telescope. It has a primary mirror to reflect and focus the incident light. A link is provided below.
refractor |riˈfraktər| noun a lens or other object that causes refraction. • a refracting telescope.
There have been a number of problems with the Hubble Space Telescope over the years. Possibly the most serious was that the primary mirror of the telescope was incorrectly made; it was out of focus! Since there was no way to test it prior to launch, scientists didn't discover this until AFTER it had already been launched from the Space Shuttle and released into orbit. It was a GIANT disappointment. (The Hubble Space Telescope couldn't be tested on the ground, because the structure isn't strong enough to support its own weight in gravity.)For almost a year, the Hubble's telescope was as blind as man with broken glasses. Another Shuttle mission was required to install a corrective lens and bring the pictures back into proper focus.Since then the biggest problems have been batteries, computer systems and gyroscopes; several gyros have been replaced, and the main computer was replaced, and new more powerful instruments installed just this summer. At the moment, I believe that everything is working properly.
Viewing satellites have lenses just like a telescope here on earth or like the Hubble telescope in space. Put a big enough lens on it and you could see people from outer space. If you're asking if you yourself can do it, dream on, only the NSA or military would have access to that kind of technology.
The Hubble is important to study objects in distant space, since it has a powerful lens's, which allows other galaxies light into it. This gives us pictures of places so far away, that it is impossible that a human will ever go there. The Hubble allows us visions of our universe, that we otherwise, would not have.
