What You Need to Know About Rifle Glass
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnification by employing a set of lenses inside the scope. The scope’s alignment can be adjusted to account for varied environmental elements like wind and elevation decreases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle 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 turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has establishes where the reticle or crosshair lies in relation to the scopes magnification. It simply indicates the reticle is behind or before the magnification lens of the scope. Looking for the most desired sort of rifle glass depends on what sort of shooting or hunting you plan on undertaking.
First Focal Plane Optic Info
First focal plane optics (FFP) feature the reticle ahead of the zoom lens. This induces the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who recognize their aim point “hold over” plus “lead” relationships for their long guns
- Shooters who do not mind the reticle is enlarged and requires more visual sight space than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who desire a clearer optic picture with less area taken up by the larger sized FFP reticle
Magnification for Glass
The measure of scope zoom you need depends on the kind of shooting you like to do. Practically every kind of rifle optic provides some amount of magnification. The volume of magnification a scope provides is established by the dimension, thickness, and curvatures of the lenses inside of the rifle optic. The magnification level of the scope is the “power” of the opic. This means what the shooter is looking at through the scope is magnified times the power element of what can generally be seen by human eyes.
About Fixed Single Power Lens Glass
A single power rifle scope or optic will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not change given that it is a set power scope.
Adjustable Power Lens Optics
Variable power rifle scopes can be adjusted between magnification power levels. It will note the zoom degree in a format like 2-10×32. These numbers mean the zoom of the scope can be adjusted in between 2x and 10x power. This always involves the powers in-between 2 and 10. The power adjustment is achieved by operating the power ring component of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Scopes
Here are some suggested scope power levels and the ranges where they could be effectively used. Highly magnified glass will not be as efficient as lower magnification level scopes given that too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to longer ranges where the shooter needs to have enough power to see where to best aim the rifle at the target.
Lens Covering for Optics
All modern-day rifle scope lenses are covered in special coatings. There are various types and qualities of glass lens coverings. Lens coating is an essential aspect of a rifle when looking into high end rifle optics and scope units. The lenses are among the most crucial parts of the optic as they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses protects the lens surface area and even helps with anti glare from refracted light and color exposure.
HD Versus ED Lens Coatings
Some glass companies additionally use “HD” or high-def glass coatings which use various processes, rare earth compounds, components, and polarizations to enhance separate color ranges and viewable definition through lenses. This high-definition coating is commonly used with more costly, high density glass which decreases light’s chance to refract through the lens glass. Some scope brands use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration may be noticeable over things with well defined outlines as light hits the object from particular angles.
Rifle Glass Lens Single Covering Versus Multi-Coating
Different optic lenses can even have different coverings 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 just 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 it will be optimally usable in lots of kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing 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 on the scope producer 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 “better” depends on the producer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Rifle Glass Lens Hydrophobic Finishing
Water on an optical lens doesn’t assist with retaining a clear sight picture through a scope whatsoever. Many top of the line and premium scope producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Alternatives for Installing Glass on Firearms
Mounting approaches for scopes come in a few options. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also normally can be found in quick release variations which use toss levers which allow rifle operators to rapidly mount and dismount the scopes.
Scope Mounting Solutions with Hex Key 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 different 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 great for rifles which require a durable, 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 Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while retaining precision. These types of mounts come in handy for shooting platforms which are moved around a lot, to take off the scope from the rifle for protection, or for sight systems which are adopted in between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It usually costs around $250 USD
Details on Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day on the range and your expensive optic by resulting in fogging and creating residue within the scope’s tube. Many optics protect against moisture from going into the scope tube with a system of sealing O-rings which are water resistant. Generally, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle sailing and are worried about the optic still working if it goes over the side and you can still find the rifle.
What to Know About Glass Tube Gas Purging
Another component of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the glass is less influenced by temperature changes and pressure distinctions from the external environment which could possibly 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 seek out.
