What You Need to Know About Rifle Glass
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by employing a series of lenses within the scope. The scope’s alignment can be adjusted to take into account different environmental elements like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the intended target. Most contemporary rifle scopes and optics have around 11 parts which are found internally and externally on the scope. These parts consist of the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other components. See all eleven parts of scopes.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the optimal type of rifle scope depends on what type of shooting you plan on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who recognize their aim point “hold over” and also “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. 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 measurement.
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who prefer a clearer optic picture without area used up by the bigger FFP reticle
About Glass Magnification
The amount of magnification a scope supplies 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.
Single Power Lens Scopes
A single power rifle scope and optic uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust considering that it is fixed.
Info on Adjustable Power Lens Optics
Variable power rifle scopes use enhanced power. The power change is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some recommended scope powers and the distances where they could be effectively used. Consider that high power scopes will not be as effective as lower magnification level optics since excessive zoom can be a bad thing. The very same idea relates to extended distances where the shooter needs to have adequate power to see exactly where to best aim the rifle at the target.
Info on Rifle Optic Lens Coverings
All modern rifle scope lenses are covered in special coatings. There are various types and qualities of glass finishes. When thinking about high end rifle targeting units, Lens finishing can be a significant aspect of defining the capability of the rifle. The lenses are one of the most crucial parts of the optic considering they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses protects the lens exterior and helps with anti glare from refracted light and color presence.
HD Versus ED Lens Coatings
Some scope producers likewise use “HD” or high-definition lens finishes which use various techniques, polarizations, components, and chemicals to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
What to Know About Single Coating Versus Multi-Coating
Various scope lenses can also have various finishes applied to them. All lenses generally have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many types of environments, degrees of light (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering 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 upon the scope manufacturer and the amount you spent on it. Both are indicators of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” coated. This suggests the lens has numerous treatments applied to them. If a lens gets several treatments, it can establish that a producer is taking numerous actions to fight different natural aspects like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally does not always suggest the multi-coated lens will perform much better than a single covered lens. Being “much better” is dependent on the producer’s lens treatment techniques and the quality of materials used in developing the rifle glass.
Anti-water Coating for Rifle Glass
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic coating.
Choices for Mounting Scopes on Firearms
Installing options for scopes come in a few choices. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also generally are made in quick release variations which use manual levers which permit rifle operators to rapidly mount and remove the scope.
Hex Key Optic Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 are designed for long range precision shooting. This type of scope install is fine for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Numerous scopes can even be switched out if they all use a compatible style mount. These types of mounts are handy for rifles which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. The majority of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less altered by temperature shifts and pressure differences from the outside environment which may potentially enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
