What You Need to Know About Glass
Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target over a range. They do this through magnification by utilizing a series of lenses within the scope. The scope’s alignment can be dialed in for consideration of many environmental elements like wind and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have around 11 parts which are located inside and outside of the scope. These scope parts include the rifle scope’s body, lenses, elevation turrets or dials, objective focus rings, and other components. Learn about the eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane a scope has identifies where the reticle or crosshair lies relative to the optic’s magnification. It actually indicates the reticle is behind or ahead of the magnification lens of the scope. Selecting the most effective sort of rifle optic is dependent on what sort of shooting or hunting you anticipate undertaking.
About First Focal Plane Scopes
First focal plane optics (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the level of zoom being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards by using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who recognize their target “hold over” and “lead” ratios for their long gun
- Shooters who do not mind the reticle is enlarged and requires more visual sight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within much shorter ranges and distances
- Shooters who would like a clearer optic picture with less area used up by the larger sized FFP reticle
Magnification for Rifle Optics
The amount of zoom a scope provides is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Scope Facts
A single power rifle optic and scope uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust since it is a fixed power optic.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom level in a configuration such as 2-10×32. These numbers mean the zoom of the scope could be set in between 2x and 10x power. This additionally utilizes the powers in-between 2 and 10. The power adaptation is achieved by working with the power ring part of the scope near the back of the scope by the eye bell.
Glass Power and Range Correlation
Here are some advised scope powers and the ranges where they may be effectively used. Consider that higher power glass will not be as efficient as lower magnification level optics because too much zoom can be a negative thing in certain situations. The same goes for extended ranges where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Rifle Optic Lens Finishing
All current rifle scope and optic lenses are coated. Lens finish can be a crucial element of a shooting system when considering high end rifle optics and scope setups.
ED Versus HD Rifle Scopes
Some optic suppliers also use “HD” or high-def lense finishings which employ different procedures, components, polarizations, and chemicals to enhance various colors and viewable definition through lenses. This high-definition finishing is frequently used with greater density glass which reduces light’s chance to refract through the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious around items with well defined outlines as light hits the object from various angles.
Info on Single Covering Versus Multi-Coating
Different scope lenses can even have different coatings applied to them. All lenses generally have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in many types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope developer and the amount you spent on it. Both the manufacturer and amount are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has had numerous treatments applied to the surfaces. If a lens gets numerous treatments, it can prove that a manufacturer is taking several steps to combat different natural factors like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This also does not necessarily mean the multi-coated lens is much better than a single covered lens. Being “much better” depends upon the producer’s lens treatment technology and the quality of components used in constructing the rifle optic.
Anti-water Lens Coverings
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Choices for Mounting Glass on Long Guns
Mounting options for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally are made in quick release versions which use toss levers which permit rifle shooters to rapidly install and dismount the glass.
Hex Key Glass Ring Mounting Solutions
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope mount is wonderful for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Multiple scopes can also be switched out if they all use a compatible style mount. These types of mounts are convenient for long guns which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used between several rifles.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by causing fogging and producing residue inside of the scope tube. A lot of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Optic Tubes
Another part of preventing the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the glass is less impacted by climate shifts and pressure distinctions from the outdoor environment which might potentially allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
