Glass Info
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target over a range. They do this through zoom by employing a set of lenses inside the scope. The scope’s alignment can be adapted for consideration of different ecological elements like wind and elevation increases or decreases to make up 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 seeing through the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle scopes and optics have around 11 parts which are arranged internally and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the optimal type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optic Info
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the amount of magnification being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where estimations are minor
- Experienced shooters who recognize their aim point “hold over” as well as “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle behind the magnifying lens. This triggers the reticle to stay at the same dimensions in connection with the amount of magnification being used. The effect is that the reticle dimensions change based upon the magnification used to shoot over longer ranges because the reticle measurements present distinct increments which vary with the magnification level. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular styles of glass are handy for:
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and spaces
- Shooters who prefer a clearer optic sight picture with less area taken up by the enlarged FFP reticle
About Optic Magnification
The amount of zoom a scope provides 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 Rifle Glass
A single power rifle optic will have a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change considering that it is fixed.
Variable Power Lens Glass
Variable power rifle scopes can be changed between magnification power levels. It will note the zoom degree in a configuration like 2-10×32. These numbers imply the zoom of the scope can be changed between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power shift is accomplished by employing the power ring part of the scope near the rear of the scope by the eye bell piece.
Power and Range Correlations
Here are some suggested scope power levels and the distances where they can be successfully used. Highly magnified optics will not be as beneficial as lower magnification glass due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The same relates to extended distances where the shooter needs sufficient power to see exactly where to best aim the rifle.
Lens Finishing for Optics
All contemporary rifle optic lenses are layered. There are different types and qualities of coverings. When researching high end rifle optics and scope setups, Lens finishing can be a very important aspect of a rifle. The glass lenses are among the most essential parts of the glass considering they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses safeguards the lens exterior as well as helps with anti glare from excess sunshine and color profiles.
HD Versus ED Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens finishes which use different procedures, chemicals, components, and polarizations to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Scope Lens Single Finish Versus Multi-Coating
Various optic lenses can also have different coverings applied to them. All lenses normally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope producer and how much you spent for it. The scope’s maker and cost are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” coated. This implies the lens has several treatments applied to them. If a lens receives several treatments, it can prove that a producer is taking numerous steps to fight different natural factors like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also does not necessarily suggest the multi-coated lens will perform better than a single covered lens. Being “much better” is dependent on the maker’s lens treatment solutions and the quality of products used in creating the rifle optic.
Anti-water Lens Finishing
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Options for Mounting Scopes on Firearms
Installing approaches for scopes are available in a couple of choices. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically come in quick release variations which use manual levers which permit rifle shooters to rapidly install and remove the optics.
Hex Key Glass Rings
Standard, clamp style 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long range precision shooting. This type of scope install is great for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, multiple scopes can also be swapped on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top design 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 maintaining the original sighting settings. These kinds of mounts are useful and beneficial for shooting platforms which are carried a lot, to take off the optic from the rifle for protection, or for optics which are used between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle optic can mess up a day of shooting and your highly-priced optic by resulting in fogging and creating residue within the scope tube. Most scopes prevent humidity from entering the optical tube with a series of sealing O-rings which are waterproof. Generally, these optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture content prevention for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on boats and are concerned about the optic still performing if it is submerged in water and you can still find the firearm.
Rifle Optic Gas Purging
Another part of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the glass is less affected by temperature level changes and pressure distinctions from the outside environment which might potentially enable water vapor to seep 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.
