Info Rifle Glass
Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They do this through zoom by using a series of lenses inside the scope. The scope’s positioning can be adapted to take into account many ecological considerations like wind speed and elevation decreases to account 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 using the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have about eleven parts which are found within and externally on the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage dials, focus rings, and other components. See all eleven parts of an optic.
About Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane a scope has identifies where the reticle or crosshair is located in relation to the optic’s zoom. It actually indicates the reticle is situated behind or before the magnifying lens of the scope. Choosing the most effective style of rifle scope depends on what sort of shooting or hunting you anticipate doing.
First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. For instance, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who know their aim point “hold over” and “lead” ratios for their weapon
- Shooters who do not mind the reticle is bigger and requires more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who choose a clearer optic sight picture without area taken up by the enlarged FFP reticle
About Optic Magnification
The quantity of magnification a scope supplies is figured out 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 Optics
A single power rifle scope uses a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not adjust since it is set from the factory.
Adjustable Power Lens Scope Details
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 magnification of the scope can be adjusted in between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power adjustment is achieved by employing the power ring part of the scope near the back of the scope by the eye bell piece.
Scope Power and Range Correlation
Here are some advised scope power settings and the distances where they can be efficiently used. High power rifle scope glass will not be as effective as lower magnification level scopes because too much zoom can be a bad thing. The same concept relates to extended ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Lens Finishing for Glass
All state-of-the-art rifle optic lenses are covered. Lens finishing is an important aspect of a shooting platform when buying high end rifle optics and scope setups.
Details on Glass Lens Coatings – HD Versus ED
Some scope manufacturers also use “HD” or high-definition lens coatings which use different methods, polarizations, chemicals, and aspects to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Scopes
Various optic lenses can also have different finishes applied to them. All lenses generally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing 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 manufacturers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Anti-water Optic Lens Finishing
Water on a lens does not help with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finishing.
Optic Mounting Alternatives
Mounting solutions for scopes can be found in a few options. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release versions which use toss levers which allow rifle operators to rapidly mount and remove the glass.
Hex Key Scope Ring Mounting Solutions
Standard, clamp style 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long distance precision shooting. This type of scope install is perfect for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. A wide range of scopes can also be switched out if they all use a complementary style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are hauled around a lot, to remove the scope from the rifle for protection, or for sight systems which are utilized in between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It generally costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Rifle Scope Gas Purging
Another element of preventing the accumulation of wetness within the rifle optic 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 changes and pressure variations from the outdoor environment which could 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 look for.
