If you’re not familiar with spotting scopes, these useful optical devices fall somewhere between binoculars and an astronomical telescope, probably a little closer to a telescope than a binocular. Designed in a more compact and portable form, a spotting scope is optimized for viewing terrestrial objects and has additional optics to present the viewing image right-side-up.Typically, refractor and some reflector telescopes will orient the image upside down and you need an extra attachment called an “erect image prism diagonal” to present the image right-side-up (but usually reversed left-to-right). A “spotting scope” already has this image orientation correcting ability built in.
The Celestron Ultima 100 – 45 Degree Spotting Scope is one of the very best you can buy with superior optics and magnification power. The Celestron Ultima 100 has a 100mm aperture (3.95 inches) which means 50 percent brighter images (allows more light in) that the Celestron 80mm model. The additional light that the larger aperture can collect also means better performance in low light conditions. Spotting scope models more commonly have smaller objective diameters, usually between 50mm and 80mm (2.0 to 3.1 inches) which means less light. The Celestron Ultima 100 has one of the largest objective diameters available.
The Celestron Ultima 100 – 45 Degree Spotting Scope is manufactured with top quality multi-coated optics and housed in a sturdy and durable refractor design. The spotting scope comes with a standard 22x to 66x zoom eyepiece. The high-quality waterproof construction is safe to use in even the most extreme weather conditions. And the convenient, easy-to-use portable scope also comes with a soft protective carrying case.
People use spotting scopes for all kinds of applications including observing nature. Serious bird lovers and outdoor enthusiasts often prefer using a high-quality spotting scope over binoculars for better and more precise remote distance viewing. Other typical spotting scope applications include target shooting (marksmen use spotting scopes on target ranges to avoid walking to the target to verify the placement of hits), and astronomy.

Man’s desire to view distant objects from a closer perspective gave birth to the concept of a binocular. In ancient time, handheld telescopic monocular was used by sailors at the sea. Then came big telescopes which were used in observatories in the 17th century. The first binocular came in the form of the opera glasses, which were used to view theatrical performances from a distance. Then, one by one, several modifications like use of Keplerian optics, Porro prism, refinements by Carl Zeiss etc have made binoculars in the form we see and use those today.
In modern society, most common binoculars are almost toy-like binoculars. Apart from this, ornithologists and bird watchers use a little bit more powerful binocular to catch the birds in sky or tree. Moreover, law enforcing agencies and defense sector also have use of binoculars to protect law and peace in a country. From the Second World War, the military binoculars have undergone a good development, and in the modern terror infested world, these have been an integral part of a military of a country just like arms and ammunition.
In the Second World War, binoculars had 15 meters of separation between two objective lenses. These heavy binoculars which were called Naval Rangefinders were used to set the range of big naval guns from a distance of 25km. Moreover, in Cold War era, military binoculars could detect active Infrared emission via built-in passive sensors. In more modern military binoculars, special filters can block laser beams used in automatic weapons of the enemy.
As the complexity of keeping peace and law in modern society is continuously increasing, the need for this kind of binocular is more than ever. The modern military binoculars are made in such a way that they can withstand heavy ordeal and rough use. For this, the outer portion of the binoculars is made with materials which can protect it. Besides, in modern military, some special kind of binoculars are used which are called “trench binoculars”. These things are made in conjunction with a binocular and a periscope, and are used from trenches during war which keep the head of the user safe. Moreover most modern military binoculars have arrangements where a soldier can fit be into his/her helmet when necessary.
Most modern military binoculars which are used by army and navy are classified into Military Binoculars with 6×30 service glass, Military Observation Binoculars, 10 x 50 Military R, Military Night Vision Binoculars etc. Each of these comes with normal/wide 50mm optical lens for maximum field of view as well as with rain proofing, fog resistance capabilities. These modern military binoculars have more modern range finding abilities built in it and for using it in darkness, most of such binoculars have Infrared facilities also built in.
The ability which detects laser pointer from enemy weapons has been mentioned earlier. Companies like Leica, Canon, Nikon, Optronics, Pentax, Swift, Simmons and Zeiss etc are building and providing these binoculars, and thus satisfy the need of defense around the globe.
Binoculars may seem like a rather insignificant thing for protecting and maintaining peace in a modern society, but its significance under the lights of points discussed above cannot be ignored.

If you are fans of spy movies or planning a career as a bank robber, the Cambridge Consultants have invented a portable piece of spy gear that enables you to see through solid objects such as bricks, concrete and etc. This amazing spy gadget is known as the Prism 200c.
The British company initially designed the Prism 200c to fit nicely into a back pack to be worn casually by law enforcement officers so that they will not be compromised during a raid or stake out.
Its usage is fairly simple; you slip the Prism 200c into a back pack and wear it. Although it is makes the backpack slightly bulkier than usual, it is useful when you are doing under cover work. You simply lean the back pack against the wall which you want to see through and the images will be displayed on a hand held screen.
The hand held will portray a 3D image of the objects or people on the other side. It detects movements and can indicate the location of humans as well as animals. Besides that, the images displayed can be changed from front, plan, or profile view with a press of a button. This allows one to have a better picture about what is occurring behind a closed door.
Observe How the Prism 200C Portable Radar Device Works
To power the Prism 200c, the gadget is equipped with a battery that lasts up to eight hours long. At the moment, the Prism 200c is exclusively for law and military purposes. It is not possible for this high powered gadget to become available to the public due to privacy rights.

A USB hub is a device which allows multiple USB devices to be connected to a computer utilizing just one USB port. Most USB ports are functional at best and are not designed to look great; however the Art Lebedev Spectrus USB Hub does not follow these rules. Based on a prism, the USB Hub allows for up to 7 USB devices to be connected (one USB port for each color in the spectrum – red, orange, yellow, green, blue, indigo, and violet).
