Advantages of Stereo Microscope in Modern Scientific Processes

Microscopes are the most important devices of the laboratories. The microscopes are very much helpful in the fields of the research laboratories as well as the scientific laboratories. There are various kinds of the complicated devices that are used in the laboratories but the use of the microscopes makes the work very easy. There are also the various kinds of the microscopes like the simple and the compound microscope.

The microscopes are available in the market in various designs. Some of the microscopes are for pathological purpose and for the educational purpose as well. There are also some of the important points that should be considered while buying the microscopes. The quality of the microscope should be tested firstly. The magnification and the clarity should be very much considered.

The invention of the microscope is said to be done by Han Janssen and Zacharias Janssen according to the Dutch envoy. Galileo Galilee developed the compound microscope with the use of the convex and the concave lenses. The stereo technology started with the movie industry. It was in the sixty’s that the use of the 3D stereo technology started and with that the stereo microscope also came into being. stereo produces the 3D image of the object. It has two independent light paths and two eyepieces that help in forming the 3D image.

The stereo microscope eliminates the disadvantage of any other microscope. There was a disadvantage in the other microscope that people were having problem in keeping one eye closed. Therefore such a problem was effectively eliminated by the stereo microscope that did not allow one eye to be closed as it had two eyepieces.

Having two eye pieces the stereo microscope is always over the conventional microscope. Many of the stereo microscopes also have the rubber eye guards and it also has the zoom lens feature that makes it a distinct microscope. One of the other most important feature of the stereo microscope is it has a dual illuminator system.

The use of the digital microscope is also increasing over the last few years. There is also one type of the digital microscope that is plugged in the projectors as well as the television. The digital microscope is very much important in the fields of education and science.

We are a renowned online store where you can buy many different types of microscopes like those for led, laboratory, research, biological, dental, fluorescence, digital, Stereo Biological etc.

Curiosity Rover lands on Mars

NASA opened a new chapter in the history of interplanetary exploration with its $2.5 billion nuclear-powered robot known as Curiosity Rover. This mobile lab can be described as the biggest rover ever sent to Mars and the successful landing has been done by lowering this six-wheeled vehicle gently with the help of a rocket-powered sky crane. The success of this mission was confirmed when the Curiosity Rover started sending images back to the earth. The rover is fully equipped with an array of advanced geology and chemistry instruments capable of analyzing samples of rocks, soils and the atmosphere of Mars. It is being run with the help of an automatic pilot with pre-programmed set of instructions.

The launching took place in November 2011 from Cape Canaveral, Florida and this spacecraft had been collecting data on radiation during its eight and half month journey. In the final moments of landing, Curiosity Rover accelerated with the pull of gravity as it neared Mars’ atmosphere and the speed had been cut down with the help of a supersonic parachute. Curiosity travelled successfully more than 567 million kilo meters and at the time of safe landing, all scientists assembled at the famous Jet Propulsion Laboratory in the US to celebrate this unique moment.

In the next two years, this car-sized rover will spend time to find out whether Mars have supported life, at least in the past. The idea that life might exist in the neighboring planet has always generated great amount of curiosity among human beings and all these mysteries are going to be revealed in the future with the help of this mission. Curiosity Rover will explore the presence of the chemical elements known as nitrogen, phosphorous, carbon, sulfur and oxygen in the atmosphere of Mars and the scientists are of the opinion that all these studies are going to break some of the preconceived notions about Mars.

Scientists may have discovered a New Moon orbiting Pluto

The recently declared dwarf planet Pluto has yet another space news to tell us. It has been observed by a team of astronomers having a new moon orbiting it. These astronomers have seen this discovery using the NASA’s Hubble Space Telescope. They added that Pluto’s new moon, the fifth in the list with the designated name P5, is seen as irregular in shape and may be 6 to 15 miles in diameter. The detection of Pluto’s fifth moon was noted in nine different sets of images taken by the Hubble’s Wide Field Camera 3. Date of detection were from the 26th of June till the 29th and then again on July 07 and July 09. The said moon, orbits its mother planet Pluto in a 58,000 mile-diameter.

The Pluto astronomers were amazed and intrigued all at the same time about this space news. They were intrigued how such a dwarf planet like Pluto can have intricate collection of moons. This new discovery will help astronomers and scientists in discovering how Pluto came to be as well as the evolutions that it underwent. Many theories have been drawn about how Pluto’s moons came to be but the favorite theory explains that all of Pluto’s moons are remnants of the Kuiper Belt and Pluto Collision billions of years ago. Kuiper Belt is a vast section past the orbit of Neptune. It is said to contain thousands among thousands of other dwarf planets.

Not only that, scientists also believed that this new discovery will help them in their planned historic flyby in Pluto in July of 2015. The Pluto team is utilizing the Hubble to search the Pluto system of any potential threat that the New Horizon spacecraft may encounter on its way. One threat being feared is that it may crush or collide with orbital debris once it flies by Pluto. The discovery will also help them design and create a safer path for the New Horizon spacecraft.
In older space news delivered, Pluto’s other moons were named, Charon, Hydra, Nix, and P4, Charon being the largest moon of Pluto. It was discovered through observations done at the United States Naval Observatory in Washington, D.C. in 1978. While in 2006, Hubble observations unveiled two more small moons for Pluto, Nix and Hydra. 2011 yielded the discovery of the fourth moon named P4.

The years following the New Horizon’s Pluto flyby are deemed to be promising and will bring about more exciting space news about Pluto. It will travel longer than any spacecraft ever did to reach their target destination which was approximated to be 9 ½ years. The New Horizon spacecraft was sent in space in 2006. It has been labeled as NASA’s fastest spacecraft having the speed of 36,000 mph (nearly 58,000 kph).

Astronomers and scientists are planning to use the Hubble’s successor, NASA’s James Webb Space Telescope, for further studies and observations of dwarf planet Pluto. With the Webb Telescopes, infrared eye, it will be capable of doing surface chemistry measurement of Pluto as well as its moons and other bodies in the Kuiper belt. It can also help in discovering if Pluto has other unseen moons. This will be the first exploration of the dwarf planet Pluto and more surprises are expected from this lonely dwarf planet.
