Mirror lenza telescopes

Mirror lenza telescopes

Mirror-lenza telescope – variation of optical systems that can be simultaneously reflective and refractive. Such a structure has become complemented by car headlights, lighthouse, such inventions are used in microscopes and telescopes. Devices can be called katadioptic, they have difference from the catoptric, because they consist of spherical mirrors and are characterized by the presence of lenses.


The mirror lens telescope was invented in 1930 in the hope of connecting the best properties of the telescopes of reflectors and refractors as a mirror in one system with a lenzov. It was invented by an optics from Estonia b. Schmidt. By title it can be understood that mirrors and lenses are attached in such structures. Based on this, the image creates, and the lenses correct the visual aberration, increasing the property of the acquired image.

The optics was lucky to achieve a full-fledged enhancement of the field of view and the volume of light, but its development of a mirror-lens apparatus was too complex in production, because of this very popularity failed to achieve. In the future, the device has been finalized and improved, and at the present time the invention has been used.

Device and principle of operation

Catadioptic telescopes include a rather complicated scheme. The course of the ray on the pipe goes several times, due to this, the device becomes miniature even with a large increase. The composition of such a telescope includes a lens, a mirror, and with an increase it reduces the image distortion, that is, you can clearly see the subject.

But there is one thing – such an optical system should be placed in advance in the place from which you want to observe, due to different temperatures of the air and the telescope, the device may not work correctly.

The device itself is small, which is an advantage, since you can take it with you to the fresh air or install it in the house, for example, on the balcony. The magnification of such a telescope is quite large, it will easily allow you to observe the planets. From it you can look at the Far Space, however, it greatly increases and therefore will not allow you to see in full length. But in general, according to the characteristics, it is an excellent tool.

Advantages and disadvantages

The advantages of such a telescope:

  1. the picture quality is very high over relatively short distances+

  2. very easy to use in operation+

  3. such a telescope does not need tuning+

  4. great focusing, even at small size+

  5. compact enough+

  6. Pipe closed, but need thermal stabilization+

  7. Suitable for balcony.


  1. Pretty high price+

  2. No thermal stabilization+

  3. The telescope is only suitable for planetary focusing+

  4. When viewing the object may distort the color.

It is worthwhile that the principle of operation of all devices is not based in the approximation, but in the amount of light. This means that it all depends on the size of the light-cutting element, it can be a lens or mirror if the parameters are good, then the light will be much.

In the modern world, telescopes are constantly changing, can replace the body, lenses and mirrors, but still their principle remains the same. There are many mirror lenses of telescope models, they vary in the price category.

Mirror-lenza telescopes can be distinguished by design, as it is classic. Such tools have a similarity with a pylon pipe, but on a tripod. They are quite high quality and clear in the picture due to the fact that they have several lenses. For example, such a telescope is usually used to view the moon, large stars, planets, it is also suitable for daytime observations. However, you will not be able to look deep into space because they do not focus in low light.

How to choose?

Catadioptric based on concave and diagonal mirrors. The creation of these telescopes is much cheaper, this affects their design. Thanks to this, you can buy such a telescope with a larger objective diameter than a refractor. Often, such devices with a large lens perfectly focus on light, their direct purpose is to consider celestial objects, as well as phenomena in space that “burn” weakly.

  1. If you are new to astronomy, then pay attention to the azimuth mount.

  2. Astronomers who are already professional in their field will suit the equatorial types.

  3. A telescope reflector is an excellent option.

  4. Refractor for in-depth study.

The pluses of refractors include cost, since they are usually inexpensive, such telescopes are small, there is no distortion in the image, and the apparatus is also stable. The tools are not small, so this is not suitable for everyone.

Mirror is more for knowledgeable and understanding astronomers, since it will be harder for beginners with it, because they look at it at an angle, inexperienced people may not understand.

Top Models

As for the best telescope models, each apparatus is good in its own way, the market provides various types and types. Mirrored lenses are suitable for everything, for example, for observations in the house or in the air. All models of these telescopes have a high image, and they also have reliable optics. For convenience, you must choose yourself. Models:

  • if you want to quickly look into space, then the model Celestron Astro Fi great – great option+

  • suitable for beginners National Geographic+

  • for the younger generation, purchase Meade Polaris 90 mm+

  • if the mirror is important to you, then Sky-Watcher BK MAK127 AZGT SynScan GOTO, good in all endeavors.

But if you always want to explore in an open space, then turn your attention to reflectors. If you prefer to watch near the city, then the refractor will be an excellent choice. In order to examine objects and get vivid and unforgettable emotions, you need an appropriate apparatus, it all depends on you and your desire, since there are plenty of types of telescopes.
