The History of Binoculars

Binoculars are two telescopes that are held together side by side. The images from the two prismatic telescopes are aligned to create binocular vision. In 1608, Hans Lippershey developed the telescope. When he tried to patent his instrument, it was not approved because other telescopes were previously known. The people that were in charge had never seen a telescope before, asked if he could make a binocular version of it, with quartz optics. He completed this in December of 1608. It was probably about three or four power and about an inch in aperture. He made two more within a few months. The original price was about 1000 florins, which he later lowered to 900 florins, which might be about 1000 dollars today. In his 18th century collection of Galileo letters, Giovanbattista De Nelli wrote that in 1618 Galileo constructed a helmet with a frame containing two small telescopes that were to be used on a ship. He called it celatone. Other writers described how a celatone in 1616 or 1617 and tested it on ships throughout 1617. In 1636, Galileo described how longitude could be ascertained by observing the positions of Jupiter’s moons. He described this by using the celatone. Daniele Chorez made optical instruments in Paris. He was thought to have made a telescope by 1625.

In about 1660, a Frenchman Francois Lassere, the Capuchin Pere Cherubin d’Orleans, developed the binocular telescope, separating the tubes with a metal frame and placing this in cardboard boxes that extended by sliding the smaller box from within the larger. He made about 30 of these in the 1660,s and 1670,s. In 1714, Peitro Patroni made a binocular telescope with silver ocular covers that swing open to reduce glare. The objectives have about 12mm of clear aperture with about 10 times magnification, and the three lens erecting system has no aperture stop. Since most of these binoculars were sold to noblemen for collectors items or conversation pieces, they were decorated with elaborated gilt tooled leather. In about 1750, Francois Baillou made binoculars with deep green lenses for solar observation. In 1790, Peter Dollond improved the binoculars by using a tube to move the objective and oculars lenses with a rack and pinion track. All of these early twin telescopes were refractors. In 1864 during the civil war, the U.S. Naval Observatory asked Alvin Clark to make binoculars that combined wide field with high magnification. This was completed in February of 1865. There have been many improvements since then. In later year’s reflector binoculars, digital, night vision is just some of the changes that have come about. Binoculars have many uses including astronomy, hunting, getting a close up view of the ball game and of course military.

Leupold Rifle Scopes - From the Beginning, The Evolution of a Masterpiece

The rifle scope is obviously a great invention, and like most inventions it was born out of necessity. Most great inventions evolve from someone finding a need for something and figuring out how to make it work. The evolution of the rifle scope began when people started attaching telescopes to rifles to maximize viewing capabilities. This idea was of course very primitive and did not provide the desired effect. The first verifiable use of a telescopic sight on a pistol dates back to 1834,but attempts to create a workable rifle scope were unsuccessful until 1880 when August Fielder managed to build the first telescopic sight that really actually worked.

This was the predecessor of all modern day rifle scopes. In 1907 a German immigrant named Fred Leupold set up a small shop in Portland Oregon repairing survey equipment. Several years later when he met inventor John Stevens, the marvelous company named Leupold and Stevens was born and still exists today. It was around 1930 after a failed hunting trip, that Leupold began making his first rifle scopes. The small company survived World War I and the great depression but it was the Second World War that changed the company forever. Working with the US Army and Navy, the engineers at Leupold learned the secrets of waterproofing and durable construction that would change the world of optics forever. The engineers learned that by introducing nitrogen gases within the scope that the optics would remain clear, waterproof and fogproof… for a lifetime.

Today Leupold and Stevens is a family owned American company with 100 years of experience. Their modern day state of the art facility employs over 600 employees in Beaverton Oregon. The Leupold engineers design, machine, assemble and test all of their optics within this facility. Only the finest material known to man are used for production of their optics especially the lenses and they are of the highest grade quality that is demanded by Leupold engineers. In addition to rifle scopes Leupold also offers a fine line of binoculars and spotting scopes as well.The products produced are made to last more than a lifetime and they are all backed by the famous Leupold Lifetime Warranty. They set all the standards that other optics manufacturers strive to achieve. Leupold optics are world renowned for their ruggedness, absolute waterproof integrity and their superior optical quality. Leupold offers a vast line of rifle scopes with both fixed and variable powers and many types of reticles. They have many different lines to chose from, sure to please any rifleman. The name Leupold is one of the most trusted, respected, and known names in the outdoor and hunting arenas worldwide.

Leupold has recently issued a counterfeit warning to its customers cautioning them to be on the lookout for counterfeit Leupold scopes that are illegally being imported from China. These fake reproductions bear many of the marks of the a genuine Leupold, making them very difficult to distinguish externally from authentic Leupold products. Recently many rifle scopes have begun to arrive at the Leupold headquarters for service. Obviously these products were not manufactured by Leupold and are not covered by the Leupold lifetime warranty. Leupold uses serial numbers on all of their optics so if one finds a suspect they can simply contact Leupold at 1-800-LEUPOLD to verify the authenticity.

To me I feel that a Leupold scope is the best scope for the money and I have many of them. I own 9 hunting rifles and they are ALL equipped with Leupolds. I personally thank Leupold for my grizzly bear and dall sheep from Alaska, my mountain lion and elk from Arizona, my black bear and mule deer from Colorado, and the 13 trophy whitetail deer from right here in Pennsylvania. Through many conditions, from rain and snow, to blizzards and fog, to tripping down mountains, and banging around on horseback, my Leupolds have NEVER let me down under any circumstances. Thanks again Leupold for a lifetime of memories!

Robert Manack writing as “Outdoorcrazy”

At 54 years old. I have over 2/3s of my lifetime in the outdoors. From my first trophy whitetail at age 16 with my Leupold 3×9 to my most recent trophy from Arizona, I will spend the rest of my life in the great outdoors. I am a die hard hunter, it is my passion. It is so much a part of me that my partner Sharon and I have created our very own website that is totally outdoor related. We are http://www.opticsandoutdoorgear.com, please stop by and visit us sometime, you’ll be glad that you did.
