About Optics
Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target over a range. They do this through magnification by employing a series of lenses inside the scope. The scope’s alignment can be adapted to account for numerous ecological aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle optics have about eleven parts which are found inside and on the exterior of the scope body. These scope parts consist of the rifle scope’s body, lenses, modification turrets, focus rings, and other components. Learn about the eleven parts of glass.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane an optic has determines where the reticle or crosshair is located in regard to the scopes magnification. It simply means the reticle is located behind or ahead of the magnification lens of the scope. Picking the most beneficial sort of rifle glass is based upon what form of hunting or shooting you intend on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who understand their aim point “hold over” plus “lead” ratios for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle
Second Focal Plane Scope Details
Second focal plane scopes (SFP) feature the reticle behind 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 reticle measurement.
- Long distance kinds of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who like a clearer optic sight picture with less room used up by the bigger FFP reticle
Rifle Scope Magnification
The quantity of magnification a scope supplies is identified 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 Scopes
A single power rifle optic uses a zoom number designator like 4×32. This means the zoom 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 set from the factory.
Adjustable Power Lens Scopes
Variable power rifle scopes have adjustable power. It will note the magnification level in a format such as 2-10×32. These numbers indicate the magnification of the scope could be set between 2x and 10x power. This always includes the powers in-between 2 and 10. The power adaptation is achieved by employing the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Rifle Scopes
Here are some recommended scope power settings and the distances where they may be efficiently used. Highly magnified optics will not be as beneficial as lower magnification level rifle scope glass considering too much magnification can be a bad thing. The exact same idea relates to longer ranges where the shooter needs enough power to see exactly where to best aim the rifle.
Details on Lens Coatings
All modern-day rifle optic lenses are covered. Lens coating can be a vital element of a rifle’s setup when looking at high end rifle optics and scope setups.
HD Versus ED Lenses
Some scope makers will also use “HD” or high-definition glass coverings that make the most of various processes, elements, polarizations, and chemical applications to extract different color ranges and viewable target visibility through lenses. This HD finish is frequently used with increased density lens glass which reduces light’s ability to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration may be obvious over things with hard shapes as light hits the object from certain angles.
Optic Lens Single Finishing Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses typically have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It needs to have a finish applied to it so that it will be efficiently usable in many kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Covering for Rifle Glass
Water on a scope’s lens doesn’t help with preserving a clear sight picture through a scope in any way. Numerous top of the line and high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface of the Steiner optic lens so the water particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Rifle Glass on Long Guns
Mounting options for scopes come in a couple of choices. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally come in quick release versions which use manual levers which permit rifle shooters to rapidly install and dismount the scope.
Hex Key Rifle Scope Rings
Standard, clamp design 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 is designed for long distance precision shooting. This type of scope install is perfect for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining accuracy. These kinds of mounts are useful and practical for rifles which are moved a lot, to remove the glass from the rifle for protection, or for optics which are adopted in between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. A lot of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another element of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the glass is less affected by temperature level alterations and pressure differences from the outdoor environment which might potentially enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
