What You Need to Know About Optics
Rifle scopes enable you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnification using a set of lenses inside the scope. The scope’s positioning can be adjusted to account for varied natural considerations like wind and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes and optics have around 11 parts which are arranged inside and outside of the scope. These parts include the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other parts. See all eleven parts of a rifle scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has determines where the reticle or crosshair is located in connection with the scopes magnifying adjustments. It literally indicates the reticle is located behind or ahead of the magnifying lens of the optic. Looking for the most reliable kind of rifle scope is based upon what style of hunting or shooting you anticipate doing.
First Focal Plane Glass Info
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 scenarios where estimations are very little
- Experienced shooters who recognize their target “hold over” as well as “lead” relationships for their long gun
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and proximities
- Shooters who like a clearer optic picture with less space used up by the enlarged FFP reticle
Magnification for Glass
The amount of zoom a scope provides is determined 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.
About Fixed Power Lens Rifle Scopes
A single power rifle scope uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust since it is a set power scope.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a format such as 2-10×32. These numbers mean the zoom of the scope can be changed between 2x and 10x power. This always involves the powers in-between 2 and 10. The power modification is achieved by operating the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power and Range of Rifle Glass
Here are some advised scope power levels and the distances where they could be efficiently used. Keep in mind that high power optics will not be as efficient as lower powered optics and scopes because increased magnification can be a bad thing. The same goes for longer distances where the shooter needs to have sufficient power to see where to properly aim the rifle.
Lens Finish for Scopes
All contemporary rifle scope and optic lenses are layered. There are different types and qualities of lens finishings. When thinking about luxury rifle targeting systems, Lens finishing can be a very important component of defining the rifle’s capability. The lenses are one of the most essential pieces of the scope because they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses safeguards the lens exterior and even assists with anti glare from refracted daylight and color profiles.
Details on Lens Coatings – HD Versus ED
Some rifle scope producers will also use “HD” or high-def glass coverings that make the most of various processes, aspects, rare earth compounds, and polarizations to extract different colors and viewable target visibility through lenses. This HD finish is normally used with more costly, high density lens glass which reduces light’s opportunity to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often obvious around items with well defined outlines as light hits the item from particular angles.
Rifle Optic Lens Single Finishing Versus Multi-Coating
Different optic lenses can also have different finishes applied to them. All lenses generally have at least some kind of treatment or finish applied to them before being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It needs to have a covering applied to it so that it will be efficiently functional in lots of types of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while reducing glare and other less beneficial 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 similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Lens Coverings
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finishing.
Rifle Optic Installation Choices
Mounting solutions for scopes can be found in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use manual levers which permit rifle shooters to quickly mount and dismount the scope.
Hex Key Glass Ring Mounts
Standard, 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope mount is perfect for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a similar design mount, a number of scopes can often be switched out on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining precision. These types of mounts are useful and convenient for rifles which are transported a lot, to remove the glass from the rifle for protection, or for scopes which are used between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can wreck a day of shooting and your pricey optic by resulting in fogging and creating residue within the scope’s tube. A lot of scopes protect against moisture from entering the scope tube with a system of sealing O-rings which are waterproof. Typically, these scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content avoidance for basic use rifles, unless you anticipate taking your rifle sailing and are worried about the optic still working if it goes over the side and you can still find the firearm.
Rifle Scope Gas Purging
Another part of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the optic is less affected by temp changes and pressure distinctions from the external environment which could potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
