All About Rifle Glass
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They do this through zoom by employing a series of lenses inside the scope. The scope’s positioning can be adjusted to take into account different ecological elements like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the target. Many modern rifle scopes and optics have about eleven parts which are arranged internally and outside of the optic. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other elements. See all eleven parts of a scope.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has establishes where the reticle or crosshair lies in connection with the scopes magnification. It simply implies the reticle is situated behind or ahead of the magnification lens of the optic. Choosing the most reliable kind of rifle scope is dependent on what sort of hunting or shooting you intend on doing.
First Focal Plane Scope Facts
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are very little
- Experienced shooters who understand their aim point “hold over” and also “lead” equations for their long guns
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnification 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 reticle measurement.
- Long distance types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who select a clearer optic picture with less area used up by the bigger FFP reticle
Rifle Scope Zoom
The quantity of magnification a scope supplies is determined 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 Glass
A single power rifle scope comes with 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 magnification of this kind of scope can not fluctuate considering that it is a fixed power optic.
About Adjustable Power Lens Scopes
Variable power rifle scopes use variable power levels. The power adjustment is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope power levels and the ranges where they can be effectively used. High power scopes will not be as useful as lower magnification level optics considering that too much magnification can be a bad thing. The very same idea applies to longer distances where the shooter needs enough power to see exactly where to properly aim the rifle at the target.
Lens Coating for Rifle Optics
All top of the line rifle optic lenses are covered. Lens coating is a significant aspect of a rifle’s setup when buying high end rifle optics and scope equipment.
Details on Optic Lens Coatings – HD Versus ED
Some scope makers likewise use “HD” or high-definition lens finishings which use different processes, components, chemicals, and polarizations to draw out different colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Optics
Different scope lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic assembly. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in many kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering 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 manufacturer and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Lens Finishes
Water on a scope lens does not support preserving a clear sight picture through a scope at all. Many top of the line or high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Scope Installation Alternatives
Installing options for scopes come in a couple of options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually come in quick release variations which use throw levers which allow rifle shooters to rapidly mount and remove the glass.
Hex Key Rifle Optic Ring Mounting Solutions
Standard, clamp type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use two detached rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for far away accuracy shooting. This kind of scope mount is good for rifles which need a durable, rock solid mount which will not move despite just how much the scope is moved or jarring the rifle takes. These are the design of mounts you want for a specialized optics system on a reach out and touch someone scouting or sniper competition long gun which will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the screws to prevent the hex screw threads from backing out after they are mounted safely in position. An example of these rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different 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 tightly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining precision. These kinds of mounts are useful and practical for shooting platforms which are carried a lot, to remove the glass from the rifle for protection, or for scopes which are adopted in between multiple rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Info Around Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your expensive optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Optic Tubes
Another component of avoiding the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the optic is less influenced by climate shifts and pressure variations from the external environment which might potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
