Glass Information
Rifle scopes permit you to exactly align a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by making use of a series of lenses within the scope. The scope’s alignment can be dialed in for consideration of separate environmental factors like wind and elevation to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the target. Many modern rifle optics have around eleven parts which are arranged within and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other parts. See all eleven parts of a rifle scope.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the optimal type of rifle scope depends on what type of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who understand their aim point “hold over” plus “lead” equations for their long gun
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the exact same dimensions relative to the quantity of magnification being used. The outcome is that the reticle dimensions alter based on the magnification applied to shoot over lengthier distances due to the fact that the reticle markings represent different increments which differ with the zoom. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular kinds of scopes work for:
- Long distance styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots happen within much shorter distances and ranges
- Shooters who would like a clearer optic sight picture without room used up by the bigger FFP reticle
Rifle Optic Zoom
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 zoom of the scope is the “power” of the scope.
Fixed Power Lens Glass Details
A single power rifle optic uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate considering that it is fixed.
Variable Power Lens Optic Facts
Variable power rifle scopes can be modified between magnified settings. The power adjustment is handled by the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Scopes
Here are some suggested scope powers and the distances where they may be effectively used. Keep in mind that high magnification scopes will not be as efficient as lower magnification level glass due to the fact that excessive zoom can be a negative thing in certain situations. The same goes for longer ranges where the shooter needs adequate power to see precisely where to best aim the rifle.
About Lens Coverings
All modern rifle optic lenses are covered in special coatings. There are various types and qualities of lens coverings. When looking at high end rifle scope devices, Lens coating can be a vital element of defining the rifle’s capability. The lenses are one of the most significant parts of the glass given that they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses shields the lens surface and assists with anti glare capabilities from refracted sunshine and color profiles.
HD Versus ED Lens Coatings
Some glass manufacturers even use “HD” or high-definition glass coverings which employ different processes, elements, chemical substances, and polarizations to draw out a wide range of color ranges and viewable target visibility through the lens. This high-definition finish is typically used with greater density glass which decreases light’s chance to refract through the lens glass. Some scope makers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable around items with hard edges and outlines as light hits the item from particular angles.
What to Know About Single Covering Versus Multi-Coating
Various optic lenses can also have various coverings applied to them. All lenses generally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. This implies the lens has had several treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can show that a manufacturer is taking several steps to combat different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also doesn’t necessarily indicate the multi-coated lens will perform better than a single covered lens. Being “better” depends on the maker’s lens treatment technology and the quality of components used in constructing the rifle optic.
Hydrophobic Lens Finish
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic covering which is water repellent.
Choices for Mounting Rifle Optics on Long Guns
Mounting options for scopes are available in a few choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release variations which use throw levers which enable rifle shooters to quickly install and remove the scopes.
Rifle Scope Mounting Solutions with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope install is excellent for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used between numerous rifles or are situationally focused.
About Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your pricey optic by bringing about fogging and producing residue inside of the scope tube. Many scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Scope Tubes
Another part of preventing the buildup of wetness inside of the rifle scope 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 influenced by temp alterations and pressure distinctions from the external environment which may possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
