What You Need to Know About Glass
Rifle scopes enable you to exactly align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target by making use of a series of lenses inside the scope. The scope’s positioning can be dialed in to account for numerous environmental things like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle optics have around eleven parts which are found internally and on the exterior of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other parts. Learn about the eleven parts of rifle scopes.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane an optic has determines where the reticle or crosshair is located in regard to the scopes magnification. It literally suggests the reticle is behind or ahead of the magnifying lens of the scope. Considering the best sort of rifle optic depends upon what type of shooting or hunting you intend on doing.
Info About First Focal Plane Scopes
First focal plane optics (FFP) include the reticle in front of the zoom lens. This causes the reticle to increase in size based upon the level of magnification being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who understand their target “hold over” as well as “lead” relationships for their long guns
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane optics (SFP) feature the reticle to the rear of the magnifying lens. This causes the reticle to remain at the very same size in relation to the level of magnification being used. The final result is that the reticle measurements change based upon the zoom chosen to shoot over longer ranges considering the reticle measurements present distinct increments which can vary with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These styles of scopes work for:
- Long distance forms of shooting where shooters have more time to make ballistic computations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who choose a clearer optic picture with less space used up by the larger sized FFP reticle
Glass Magnification
The amount of zoom a scope offers is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Single Power Lens Rifle Scopes
A single power rifle optic will have a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not fluctuate since it is set from the factory.
About Adjustable Power Lens Optics
Variable power rifle scopes have adjustable power. It will list the zoom level in a configuration such as 2-10×32. These numbers imply the zoom of the scope could be changed between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power adaptation is achieved by working with the power ring component of the scope near the back of the scope by the eye bell piece.
Rifle Glass Power Level and Range Correlation
Here are some suggested scope power levels and the distances where they may be successfully used. High power scopes will not be as effective as lower powered optics considering too much magnification can be a negative aspect depending on your shooting distance. The exact same concept applies to longer ranges where the shooter needs enough power to see precisely where to properly aim the rifle.
Details on Rifle Optic Lens Covering
All state-of-the-art rifle optic lenses are coated. Lens coating is a crucial aspect of a rifle’s setup when purchasing high end rifle optics and scope setups.
Info on Lens Coatings – HD Versus ED
Some optic makers will also use “HD” or high-definition lense finishings that apply various procedures, aspects, polarizations, and chemical applications to extract various colors and viewable target definition through lenses. This HD covering is typically used with more costly, high density glass which reduces light’s ability to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be visible over items with hard edges and outlines as light hits the item from certain angles.
Details on Single Coating Versus Multi-Coating
Different optic lenses can likewise have different finishes applied to them. All lenses generally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope maker and just how much you paid for it. Both the make and cost are indications of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. This means the lens has numerous treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can establish that a producer is taking multiple actions to combat various environmental elements like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally does not always imply the multi-coated lens is better than a single layered lens. Being “better” depends upon the maker’s lens treatment solutions and the quality of glass used in creating the rifle scope.
Hydrophobic Rifle Glass Lens Finishing
Water on an optical lens doesn’t improve keeping a clear sight picture through an optic in any way. Lots of top of the line or high-end optic producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the exterior of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Alternatives for Mounting Rifle Glass on Firearms
Installing options for scopes can be found in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also normally come in quick release versions which use toss levers which permit rifle operators to rapidly mount and remove the scopes.
Hex Key Glass Ring Mounting Solutions
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope mount is great for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Rings
These kinds 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 comparable design mount, multiple scopes can often be swapped in the field. The quick detach design is CNC machined 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, taken off of the rifle, and remounted while keeping precision. These kinds of mounts come in convenient for shooting platforms which are transported a lot, to remove the optic from the rifle for protection, or for sight systems which are chosen for use between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can mess up a day of shooting and your highly-priced optic by triggering fogging and making residue within the scope tube. Most optics prevent wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Normally, these water-resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample wetness avoidance for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are worried about the optic still working if it goes over the side and you can still salvage the rifle.
Rifle Optic Gas Purging
Another component of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the scope is less influenced by temperature level shifts and pressure distinctions from the outdoor environment which might potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
