What You Need to Know About Rifle Glass
Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They do this through zoom by utilizing a series of lenses within the scope. The scope’s positioning can be adjusted for consideration of various natural factors like wind and elevation to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the target. Many contemporary rifle scopes have around 11 parts which are located internally and on the exterior of the optic. These parts include the rifle scope’s body, lenses, windage dials, focus rings, and other parts. Learn about the eleven parts of rifle optics.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the best type of rifle scope depends on what type of shooting you plan on doing.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who understand their target “hold over” and “lead” correlations for their weapon
- Shooters who don’t mind the reticle is bigger and requires more visual sight room than a SFP reticle
About 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” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who like a clearer optic picture without room taken up by the larger size FFP reticle
Rifle Optic Magnification
The level of scope zoom you need on your optic depends upon the kind of shooting you would like to do. Almost every kind of rifle scope delivers some degree of magnification. The amount of magnification a scope delivers is determined by the dimension, thickness, and curves of the lens glass within the rifle optic. The magnifying level of the optic is the “power” of the glass. This means what the shooter is aiming at through the scope is amplified times the power factor of what can typically be seen by human eyes.
Fixed Power Lens Glass Details
A single power rifle scope will have a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate considering that it is fixed.
Variable Power Lens Rifle Glass Facts
Variable power rifle scopes can be modified between magnified levels. The power modification is performed using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope powers and the ranges where they could be effectively used. Highly magnified glass will not be as effective as lower magnification glass given that too much magnification can be a negative aspect depending on your shooting distance. The same idea applies to longer ranges where the shooter needs to have sufficient power to see where to best aim the rifle at the target.
Details on Scope Lens Coatings
All modern rifle scope and optic lenses are layered. Lens finish can be a significant element of a rifle’s setup when looking into high end rifle optics and scope setups.
HD Versus ED Lenses
Some rifle glass manufacturers will also use “HD” or high-def lens coverings which take advantage of different processes, elements, chemicals, and polarizations to extract a wide range of color ranges and viewable definition through lenses. This high-definition finishing is typically used with more costly high density glass which brings down light’s potential to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration can be visible around objects with hard outlines as light hits the item from specific angles.
Single Finish Versus Multi-Coating
Different optic lenses can likewise have different coverings used to them. All lenses normally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Finishing for Rifle Scopes
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic covering which is water repellent.
Glass Installing Choices
Mounting solutions for scopes can be found in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also usually can be found in quick release versions which use manual levers which enable rifle operators to rapidly mount and remove the glass.
Hex Key Optic Rings
Normal, 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 two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is wonderful for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle. If they all use a comparable style mount, a number of scopes can often be switched out on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top design 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 handy for shooting platforms which are carried a lot, to take off the scope from the rifle for protection, or for sight systems which are used in between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics manufacturer. It typically costs around $250 USD
Details on Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. Most scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
About Optic Tube Gas Purging
Another component of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the optic is less affected by condition shifts and pressure differences from the external environment which could possibly 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 seek out.
