What You Need to Know About Optics
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by employing a series of lenses within the scope. The scope’s alignment can be adapted to account for different environmental considerations like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle scopes have about eleven parts which are found within and on the exterior of the scope body. These scope parts consist of the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other components. Learn about the eleven parts of optics.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the best type of rifle optic depends on what type of shooting you plan on doing.
Info on First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who recognize their aim point “hold over” and “lead” ratios for their rifles
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (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 reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who select a clearer optic picture without room taken up by the larger sized FFP reticle
Scope Magnification
The extent of scope zoom you need depends on the style of shooting you choose to do. Almost every type of rifle glass delivers some amount of zoom. The volume of magnification a scope offers is determined by the diameter, density, and curves of the lens glass within the rifle scope. The magnification level of the optic is the “power” of the scope. This suggests what the shooter is checking out through the scope is magnified times the power element of what can normally be seen by human eyes.
Info About Fixed Single Power Lens Scopes
A single power rifle scope or optic will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate because it is a fixed power scope.
Variable Power Lens Glass Facts
Variable power rifle scopes use variable power levels. The power change is achieved by the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope power levels and the distances where they can be successfully used. Remember that higher magnification optics and scopes will not be as practical as lower powered optics because too much zoom can be a bad thing. The exact same idea applies to longer distances where the shooter needs to have adequate power to see exactly where to best aim the rifle at the target.
Rifle Scope Lens Finishing
All modern-day rifle glass lenses are layered. Lens coating is a vital aspect of a rifle system when looking at high end rifle optics and scope equipment.
ED Versus HD Glass
Some scope makers likewise use “HD” or high-definition lens finishes which use different procedures, chemicals, components, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
About Single Coating Versus Multi-Coating
Different optic lenses can even have various finishes applied to them. All lenses usually have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer 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 “much better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
What to Know About Anti-water Coating
Water on a lens doesn’t help 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 covering.
Optic Mounting Alternatives
Installing approaches for scopes come in a couple of options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also usually are made in quick release versions which use manual levers which allow rifle shooters to rapidly mount and dismount the glass.
Rifle Optic Mounts with Hex Key Rings
Normal, 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 separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope install is great for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. Multiple scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping precision. These kinds of mounts come in convenient for rifles which are moved a lot, to take off the scope from the rifle for protection, or for scopes which are adopted in between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It generally costs around $250 USD
What to Know About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. The majority of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another element of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the scope is less altered by temperature level changes and pressure variations from the external environment which may possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
