history of rifle scopes  -  laser range meter price
Our rifle telescope is most directly related to the folding telescope, and the first practical version can be seen in about 1608 of the Netherlands.
These first folding telescopes are considered to be the masterpieces of Hans limpercher and Zakaria Jansen.
Manufacturer and Jacob Metius
We may be more familiar with the name Galileo, who heard about the invention in 1609 and started making his own version.
The first experiment given to the shooter telescope dates back to the Early 17 th century, but all early attempts have practical or performance limitations.
The first documented telescopic rifle aiming device was invented by Morgan James of Utica, New York, shortly after 1835. John R.
Civil engineer Chapman studied some concepts and designs with James who made Chapman-James sight.
In 1855, William Malcolm of Syracuse, New York, began to create his own work.
Malcolm combines the color-eliminating lens with the lens used in the telescope.
He also improved the adjustment of wind and altitude.

During the Civil War, Amington, Vermont was the standard.
During the Civil War, telescopes were used by both sides and worked well.
There are some noteworthy shots and some hit rumors from 1000 yards or more.
It is reported that Federal General Sedgwick was killed by a sniper 1000 yards away in spport siwania.
The distance actually measured is about 550 yards, which is still very impressive for black powder rifles in combat conditions ,(

The variable power rifle range was not developed until the end of 1940, and it has been several years since it was reliable in terms of performance and longevity.
After adjusting the elevation or wind force, they usually do not return to zero and fog up in wet conditions or just from the elevation change.
There is a waterproof range of about 1960.
The introduction of the variable power rifle mirror also introduces the problem of installing the cross line in the first or second focal plane.
Generally speaking, the range with the first focal plane cross line will cost more than the range with the second focal plane cross line.
In the first focal plane optical system, the cross line unit is located in front of the lens that controls the magnification, so as the magnification changes, the cross line looks smaller and smaller.
The cross line is actually keeping its size relative to the target, which means that distance estimation, trajectory compensation, and lead can be performed under any available magnification.
The more common arrangement of the variable power rifle range is to install the cross line on the second focal plane.
This arrangement is cheaper in design and production compared to the first focal plane cross line.
The second focal plane splitter unit is mounted at the end of the splitter, so as the magnification changes, the splitter looks to maintain the same size.
This means accurate positioning, keeping
Only in the absence of some kind of conversion can take over and lead on a zoom-in setting.
The basic principles of the range design have remained the same since 1960, and some details have been added, such as more
Coating lens in 1970s and parallax adjustment (
Only need to enlarge more than 8 times)
, And lighting cross lines that can extend the shooting time in the morning and evening.
The basic cross alignment has been enhanced in many varieties, including the adaptation of the Military Cross alignment
Point ranging system.
Each manufacturer has also created a proprietary range cutting line.
The most important and recent change in the design of the rifle range is the inclusion of the laser range finder in the range itself.
In 1997, Swarovski Optik launched the LRS series telescope, the first rifle telescope in the civil market with an integrated laser range machine.
LRS can measure a range of up to 600 m (660 yard).
LRS attractions have been discontinued, but Burris and Bushnell offer a range of similar but superior features commercially.
There is a range within each price range and there are a variety of options.
Consider your needs carefully and evaluate the options available and you will find a range of rifles that will suit you.
