Our rifles are most directly related to telescoping, of which the first practical versions were observed around 1608 in the Netherlands. These first refracting telescopes are attributed to Hans Lipsers and Zaharias Jansen, creators of performances and Jacob Metyus. We are probably more familiar with the name Galileo Galileo, who heard about the invention in 1609 and continued to make its version. The first experiments that give telescopes the shooters are back in the early 17th century, but all early attempts had practical or restrictive features.
The first documentary telescopic vision was invented shortly after 1835 by Morgan James of Utica, NY. John R. Chapman, a civil engineer, worked with James on some of the concepts and designs, and they made Chapman-James look. In 1855, William Malcolm of Syracuse, New York, began to produce his own view. Malcolm built in achromatic lenses like those used in telescopes. It also improved the wind and height settings. Malcolm's landmarks and those made by Mr LM Amidon from Vermont were the standard during the Civil War.
During the Civil War, telescopic sights were well used by both sides. There were a number of remarkable pictures and some rumors of hits of 1000 yards or more. It is reported that General Sedgwick was killed by a sniper at a distance of 1000 yards in the USSR. The actual measured distance is about 550 yards, which is still very impressive for a black rifle in combat conditions (the shooter shoots from wood).
By the end of the 1940s, variants with variable power rifle were not developed, and a few years ago they were reliable products in terms of both productivity and longevity. They often did not return to zero after adjusting to altitude or wind and fogging in wet conditions or just by height. Around 1960 waterproof objects appeared.
The introduction of a range of a variable power rifle also introduced the question of network installation of the first or second focal plane. In general, the first focal plane range will cost more than one with a second focal plane. In the lens of the first focal plane the cell of the grid is located at the front of the lenses that control the level of magnification so that the level of magnification changes the mast will appear larger and smaller than the shooter's perspective. The network actually maintains its target size, which means that the range, trajectory and conductor compensation can be made at any available zoom level.
The more common position of the scope of the rifle rifle is to have a grid in the second focal plane. This scheme is cheaper to design and produce than the first focal plane. The second focal plane mesh cell is mounted at the end of the erector tube so the zoom level changes, but the target remains the same size. This means that accurate metering, hold, and connections can only be done with an adjustment setting without any conversion.
The basics of reach design have remained virtually the same since the 1960s with some extra details such as multilayer lenses in the 1970s and correction of the parallax (just over 8x magnification) and illuminated articles that can extend the time for morning and evening shooting. The main cross-circle has been improved in many varieties, including adaptations of the military Mil-Dot search system. Each manufacturer has also created patented grids to find a range.
The most important and latest change in gun scope design is the inclusion of laser rangefinders in the range itself. In 1997, Swarovski Optik presented the telescopic vision of the LRS series, the first field of shooting in the civil market with a built-in laser rangefinder. LRS can measure ranges up to 600 meters (660 yards). LRS sights have come out of production, but bands with similar but superb features are offered by Burris and Bushnell. Bands are available in each price range and with a wide variety of options. Carefully consider your needs and consider the options available and you will find a range of rifles that is ideal for you.
