Who was so bothered with chromatic aberration that he built a telescope that used mirrors instead of lenses?
There were many inventors that had ideas and even drawn out ideas on building a telescopes that used mirrors instead of lenses, but here are a few:
- Galileo, Giovanni, and Francesco Sagredo (with others, talked about this idea)
- Cesare Caravaggi (reported to have built one)
- Niccolò Zucchi (again reported to have built one)
- James Gregory (most notable, but had no working models)
- Robert Hooke (built a working model)
- Isaac newton (generally credited with constructing the first practical reflecting telescope)
Hence, most would credit Isaac Newton for building the first practical reflecting telescope.

Does a reflecting telescope gather light with a lens or a mirror?
A reflecting telescope gathers light with a mirror instead of a lens. The mirror reflects light to a focus point where the image is formed. This design eliminates chromatic aberration that can occur with lenses.
WHAT devices is chromatic aberration a problem for astronomer?
Chromatic aberration can be a problem for astronomers using refracting telescopes and camera lenses, as it can cause color fringing and reduce the image quality by not focusing all colors to the same point. Reflecting telescopes, which use mirrors instead of lenses, do not have this issue.
What problem do refractor telescopes have that reflectors dont?
There are several disadvantages with a refracting telescope.1. Chromatic aberration is one, where all colours are not focused at the same point.2. The mass of the lens, if large, could cause it to change shape as it is moved.3. It is essentially impossible to have an optically perfect lens surface, and any minute imperfection causes 'confusion' of the light ray passing through that point.4. Any lens surface will cause some reflection of light - light lost to the detector at the end point. You must have seen reflections of yourself, or of some landscape, from an ordinary transparent window glass. These reflections will re-reflect within a lens system, causing some optical confusion - loss of quality of the image.Large modern reflector type telescopes avoid these problems by minimizing the number of glass surfaces between the incoming light and the recording surface. These days, the recording surface is usually a cmos, or similar, solid state detector.
Reflecting telescopes are popular because they're than a refracting telescope?
Reflecting telescopes are popular because they are generally more compact and can be built in larger sizes without the issues of chromatic aberration that affect refracting telescopes. They use mirrors instead of lenses, which allows for a simpler design and easier manufacturing of large apertures. Additionally, mirrors can be supported from behind, reducing the risk of distortion that occurs with heavy lenses. Overall, these advantages make reflecting telescopes more versatile and effective for astronomical observations.
Reflecting telescopes differ from refracting telescopes in having?
Reflecting telescopes use mirrors to gather and focus light, while refracting telescopes use lenses. Reflecting telescopes tend to be more compact and easier to support larger apertures, making them popular for professional astronomical research. Additionally, reflecting telescopes are less affected by chromatic aberration compared to refracting telescopes.
Can aberration occur in a mirror?
Chromatic aberration does not occur in a mirror because chromatic aberration is caused by the different colors of a light being bent different amounts. Mirrors do not care about the different colors as they only relfect the light instead of refracting it.

Who invented chromatic lens?
Sir Isaac Newton is credited with inventing the first practical reflecting telescope, which used a concave mirror as the primary optical element instead of a lens. This design helped to minimize chromatic aberration, a common issue associated with traditional refracting telescopes that used lenses.

What does a refracting telescope do and how does it differ from other types of telescopes?
Ah, a refracting telescope is a wonderful invention! It works by using a lens to bend or refract light, helping us see objects in the distance with more clarity. Unlike other types of telescopes, like reflectors or catadioptrics, refracting telescopes use lenses instead of mirrors to gather and focus light. Remember, there's no right or wrong choice when it comes to telescopes – each one has its unique beauty and purpose!

Who used the first microscope?
The first record of the use of lenses to manipulate images was in Greek and Roman writings of around 1000 A.D. As for the origins of someone using lenses to magnify a minute object, it is unclear. Most scientific instruments have a clear place in the historical records when they were formed and who created them, not the microscope though. The definition of the microscope makes it difficult to determine when it was first created. Since there were lenses dating back to ancient societies, how do we say when those lenses were used to look at minute objects? It is practically impossible to say when a single lens was used in that fashion. Credit for the first compound microscope (multiple lenses) is generally given to Zacharias Jansen and John Lippershey of the Netherlands, in 1590. It is likely that the microscope was a result of work made on the telescope. The telescope had much more practical uses in that time, because it could be used for maritime navigation.This idea is supported by the account of one of the first compound microscopes, which was six feet long and had a one inch barrel with a lens at either end. After the compound microscope the next major development was in lenses. Half a century after the compound microscope, both Anthony van Leeuwenhoek and Robert Hooke realized that lenses with very short focal lengths was the key to more magnification. This meant the use of extremely double convex or spherical lenses. They also used lenses made of pure quartz, creating a more pure glass instead of the poor quality, greenish glass of the day. The problem of making lenses in this fashion was that it created chromatic aberration. This aberration is because different wavelengths of light are refracted different amounts, resulting in a smeared image instead of a clear one. In 1758 John Dollard patented an achromatic lens. Even with this new lens, it was not until 1930 when Lister was able to use it to alleviate the problem of chromatic aberration. Much of the interim time was spent on telescope technology. Another form of the microscope, first proposed by Isaac Newton in 1692, is the reflecting microscope. In this case the light would not pass through a lens, but would reflect off of a concave mirror. Since all light is reflected the same, there would be no problem with chromatic aberration. The first reflecting microscope was made by Barker in 1736. This model was developed directly from reflecting telescope designs. Reflecting microscopes are used today, but the transmission type are much more prevalent.
