All About Optics
Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target at range. They do this through magnification using a series of lenses inside the scope. The scope’s positioning can be dialed in for consideration of many ecological elements like wind speed 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 on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes and optics have around eleven parts which are located internally and outside of the scope. These optic pieces include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other components. See all eleven parts of a rifle optical system.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the finest type of rifle glass is based on what type of shooting you plan on doing.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who have an idea for their target “hold over” plus “lead” equations for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This triggers the reticle to remain at the very same size in relation to the level of magnification being used. The final result is that the reticle measurements alter based upon the magnification used to shoot over lengthier ranges given that the markings present different increments which change with the zoom. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular sorts of optics are handy for:
- Far away types of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and spaces
- Shooters who want a clearer optic sight picture without room used up by the enlarged FFP reticle
Optic Magnification
The amount of magnification a scope supplies is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Scope Details
A single power rifle optic and scope uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate since it is a set power scope.
Adjustable Power Lens Scope Facts
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification amount in a configuration such as 2-10×32. These numbers imply the magnification of the scope could be changed in between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power modification is achieved by working with the power ring component of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range of Scopes
Here are some advised scope power settings and the distances where they could be effectively used. Highly magnified optics will not be as effective as lower powered rifle scope glass because too much zoom can be a negative aspect depending on your shooting distance. The very same idea applies to extended distances where the shooter needs to have increased power to see precisely where to best aim the rifle.
Glass Lens Coating
All contemporary rifle scope and optic lenses are layered. There are different types and qualities of lens coverings. When thinking about high end rifle targeting setups, Lens coating can be a critical element of defining the capability of the rifle. The glass lenses are among the most critical pieces of the optic as 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 surface area and also improves anti glare capabilities from excess sunlight and color profiles.
HD Versus ED Lens Coatings
Some scope makers likewise use “HD” or high-definition lens finishings which use different methods, chemicals, components, and polarizations to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Details on Single Finish Versus Multi-Coating
Different scope lenses can even have various coatings applied to them. All lenses normally have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally functional in numerous kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much money you spent paying for it. Both the manufacturer and amount are indications of the lens quality.
Some scope manufacturers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of products used in developing the rifle scope.
Hydrophobic Lens Coatings
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic finishing which is water repellent.
Rifle Glass Mounting Choices
Installing options for scopes come in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use manual levers which permit rifle operators to quickly install and remove the scopes.
Hex Key Scope Ring Mounts
Standard, clamp type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on the tops of rifles. These kinds of scope mounts use double individual rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for far away accuracy shooting. This kind of scope mount is great for rifles which require a resilient, rock solid mount which will not move no matter just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you really want to have for a faithful optics system on a reach out and touch someone scouting or tournament rifle that will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on screws to prevent the hex screws from backing out after they are mounted tightly in position. An example of these mounting rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Rifle Glass Mounts with Quick-Release Cantilever Rings
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 even be swapped out if they all use a similar design mount. These types of mounts come in handy for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles or are situationally focused.
What to Know About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can destroy a day on the range and your expensive optic by triggering fogging and making residue within the scope’s tube. Many optics protect against humidity from going into the optical tube with a series of sealing O-rings which are water resistant. Usually, these water resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough humidity prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still functioning if it goes overboard and you can still retrieve the firearm.
About Optic Tube Gas Purging
Another component of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the optic is less impacted by temp changes and pressure variations from the outdoor environment which may possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
