Telescopic Lenses Research Paper

Although, Galileo did not invent the telescope, he is thought as the inventor of the telescope. Hans Lippershey was the person who invented the telescope in 1608. Galileo learned about the spyglass in 1609. He thought that learning about spyglass was so exciting and interesting. His interest of the spyglass led him to the discovery of improving the telescope. In order to discover deeper, Galileo began to experiment with making the telescope and polished the lenses of his own telescope to increase the range about eight to nine times further. Due to Galileo’s improvement of his telescope’s range, he was the first person to discover sunspots, to see the moon’s craters, and to keep on track of the phases of

For this experiment, the formulas used are the lens equations 1/f = 1/di + 1/do to find the focal lengths of the lenses, M = fo/fe for the prediction of magnification, and M = Hi/Ho for the actual measurement of magnification. According to theory, a telescope consisting two convex lenses acting as objective and eyepiece lens will form an inverted, magnified and virtual image. From the pictures taken using the telescope, this theory has

Meridian has been manufacturing fine telescopes for 80 years and has developed a well-earned reputation for quality craftsmanship. The company itself produces and sells two distinct lines of telescopes, which are produced in its 200,000 square feet facility. Furthermore, both lines have been developed to appeal to distinct target audiences who have an interest in the company’s products. The older line, for which there has been steady demand, consists of small professional telescopes that ultimately have laid the foundation for Meridian’s strong reputation. Following the success of

Earlier on, dating back to the Romans, glass was used to magnify objects for easy viewing and by the 13th century the first glass eyepiece was invented by the Italian inventor Salvino D'Armate. Through the years, methods were developed to created magnifications up to 3x-5x. These primitive lens were frequently used during examination of tiny insects such as ants or fleas.

Herschel began to use the small telescopes they had in those days in order to observe the sky. These telescopes could only see so far, which made Herschel very frustrated because he could not see the stars and the planets as well as he would have liked to. In 1773, Herschel started to build his own telescope with the help of his siblings. His telescope became more advanced than the telescopes that were available at that time and was able to see farther into

Although he did not invent the telescope, the modifications Galileo made to the earliest telescopes lead to the discoveries that earned him the title, Father of Modern Astronomy. Galileo introduced his first telescope just weeks after seeing Hans Lippershey’s telescope design. Galileo’s telescope had the power to magnify up to twenty times, while Lippershey’s only magnified up to three times (“Who Invented the Telescope”). Having this incredible magnification made it possible for Galileo to make many astronomical discoveries. Before his powerful telescope, people thought of the moon of a perfectly smooth sphere. Galileo was able to see that the moon was in fact full of craters and mountains. He was also able to discover sunspots and Jupiter’s four moons, but the greatest find that Galileo had was the confirmation of the Copernican system. The Copernican system was the theory that the universe was heliocentric rather than geocentric; meaning that the sun was the center of the universe opposed to the common belief of Earth being the center of the universe. Galileo wrote a five hundred-page essay called The Dialogue which was a novel outlining his research on the Copernican system in the form of conversation between three men. One man believed strongly in a heliocentric universe (representing Galileo), one man believed strongly in a geocentric universe (representing Pope Urban

William Herschel was a builder of telescopes. He made them better and sold them for profit. However, his motivation for making better telescopes was not profit, it was to answer his questions about space. When he looked into space through a telescope he could see that there was more that he wanted to see. It all started when he noticed a spot on Orion’s sword. William spent a lot of time improving telescopes so that he could see deeper into space. William Herschel discovered what we now know as the planet Uranus. He originally thought it was a comet. His quest to learn more about space lead him to make improvements on telescopes. He relied on the knowledge of others to help him do this. His brother often helped him with the mechanical

What we consider the modern microscope can be traced back to Holland in the 1590s. Hans and Zacharis Jensen, a father and son team of spectacles makers, are usually listed as the original inventors. Their microscope was simple by today’s standards; it included three sliding tubes with lens at both ends that opened up to eighteen inches when fully extended. The magnification power was generally considered to be about nine times. Even though the objects were magnified, they were blurry. Croft, the author of Under the Microscope: A Brief History of Microscopy, explains that the early devices had severe chromatic aberrations, which consist of color halos surrounding the object making clear viewing problematic. Over the course of the 17th and 18th centuries vast improvements occurred in the field of microscopy including magnification, size, and clarity. Microscopes were to become more portable, and less expensive allowing them to become a instrument commonly found in drawing

The only thing standing in Edwin’s way of getting a clean picture of the stars was this thing known as the Earth’s atmosphere, which because of the fluidic gas and dust that make up the atmosphere it often “blurs visible light, causing stars to twinkle and making it difficult to see faint stars.”(Dunbar) As this makes his job virtually impossible, a German scientist comes up with the idea of a telescope in space to not only see farther but also to see clearer, this was a crucial turning point in Hubble’s findings and will eventually lead to the one of the greatest and most recognized theories around the world.

William Herschel is remembered as a great musician and astronomer of the late 1700’s. He is especially known for his discovery of Uranus in 1781. But with such limited technology, how was he able to make such a discovery? Well Herschel was a builder and seller of telescopes. Building off on Newton’s discovery that in a telescope “different colours, as they [pass] through the objective lens at the upper end of the tube, [are] bent (‘refracted’) by slightly different amounts and… [come] to a focus at slightly different distances from the objective” (Hoskin) creating an unclear, and distorted image. Herschel was able to fix this problem and create a telescope that would create a perfectly clear image. His solution was to “replace the lens [with]

There are many differences between the telescope that were being used during the 17th Century and that of now. Telescopes that were used by astronomers such as Galileo back in the 17th Century were very compact and lightweight. It wasn't very advanced, as a person could just pick it up and look through it. The power of these early telescopes were limited to just our Solar System, which disabled the potential to see beyond to other galaxies.

The use of the telescope led him to discover new characteristics of space and the solar system. He discovered Jupiter’s four largest moons and the rings of Saturn. He also discovered that the Milky Way galaxy is comprised of stars. The observation of mountains on the moon was made by Galileo as well. He also made numerous discoveries within these discoveries.

Scientists came up with a solution to correct the defect in which they came up with a replacement "contact" lens called COSTAR. The Corrective Optics Space Telescope Axial Replacement consisted of several minute mirrors that would intercept the beam of the flawed mirror and relay the corrected beam to the scientific instruments at the focus of the mirror.

As proposed in an article posted on amazing space.org, “The telescope, a basic reflector with a 94.5 in (2.4 meters) mirror.” While also having being a second mirror that the light bounces to to. Within that mirror, many instruments were compacted together that allowed for clear and visible views in infrared and ultraviolet light. It was different compared to any other ground based telescope whereas it allowed astronomers to observe and witness details that had never been seen before due to Earth being in the way for those other telescopes. The telescope revolves around the earth completely every ninety-seven minutes at the speed of five miles per second, allowing for many observations in space. The observations occur when light hits the main mirror and then bounces towards the second mirror in which the second one focuses the light. The telescope began to be created in 1977 and was originally supposed to launch during the year of 1985. Unfortunately an accident had occurred when a space shuttle challenger exploded and flights into space took a halt. It was finally launched on April 4th of 1990 once the halt had stopped. The improved observations had begun and the history of astronomy had changed. Unfortunately there were some minor setbacks that had to be dealt with. One setback was that the primary mirror was ground incorrectly in which the curve of it was too flat. It was off just

In 1609, Galileo Galilei, using “spyglass” which allowed one to see things closer than they appeared, made an early version of the telescope. With it, he observed the skies in a way no one had before. He discovered the moon isn’t perfectly globular, it has craters, the Sun has sunspots, Venus orbits the Sun (contrary to widespread belief in his time), and then he observed four “stars” around Jupiter (“Our Solar System”).
