Glass Facts
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnification by making use of a set of lenses inside the scope. The scope’s alignment can be dialed in to take into account many environmental considerations like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle optics have about 11 parts which are found inside and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage dials, objective focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the best type of rifle scope is based on what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are minimal
- Experienced shooters who recognize their aim point “hold over” as well as “lead” relationships for their long gun
- Shooters who don’t mind the reticle is bigger and takes up more visual sight room than a SFP reticle
Info on Second Focal Plane Glass
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.
- Long distance kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots take place within shorter ranges and spaces
- Shooters who would like a clearer optic sight picture with less room used up by the larger size FFP reticle
About Rifle Scope Zoom
The amount of magnification a scope offers is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Single Power Lens Optics
A single power rifle optic will have a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not change given that it is set from the factory.
Variable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification increments. These types of scopes will list the magnification amount in a configuration like 2-10×32. These numbers indicate the zoom of the scope could be set in between 2x and 10x power. This also incorporates the power levels in-between 2 and 10. The power adaptation is accomplished using the power ring component of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope power levels and the distances where they can be successfully used. Keep in mind that high magnification optics and scopes will not be as efficient as lower magnification level optics since increased magnification can be a detractor. The exact same concept applies to extended ranges where the shooter needs to have sufficient power to see exactly where to properly aim the rifle.
Details on Optic Lens Finishing
All present day rifle glass lenses are layered. Lens finishing is an important element of a shooting platform when purchasing high end rifle optics and scope equipment.
HD Versus ED Rifle Scope Lens Coatings
Some rifle glass manufacturers additionally use “HD” or high-def glass finishings that apply different processes, chemicals, components, and polarizations to extract a wide range of colors and viewable target definition through lenses. This high-definition finish is typically used with greater density lens glass which brings down light’s chance to refract through the lens glass. Some scope producers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be obvious around objects with defined outlines as light hits the object from specific angles.
Single Finishing Versus Multi-Coating for Rifle Optics
Different optic lenses can also have various finishings applied to them. All lenses typically have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a coating applied to it so that it will be efficiently usable in many types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering 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 upon the scope designer and how much you spent paying for it. The scope’s maker and cost are indicators of the lens quality.
Some scope manufacturers also 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 innovation and the quality of products used in developing the rifle scope.
Anti-water Lens Finishes
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 optic makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Alternatives for Mounting Optics on Long Guns
Mounting approaches for scopes come in a few choices. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release versions which use manual levers which permit rifle operators to quickly mount and remove the optics.
Hex Key Rifle Scope Rings
Normal, 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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope install is great for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle. A wide range of scopes can also be switched out if they all use a complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving the original sighting settings. These kinds of mounts are useful and beneficial for shooting platforms which are moved a lot, to remove the optic from the rifle for protection, or for aiming systems which are adopted in between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle scope can mess up a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Scope Gas Purging
Another component of preventing the buildup of wetness inside of 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 affected by temperature shifts and pressure variations from the external environment which might possibly enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
