Rifle Glass Details
Rifle scopes allow you to exactly align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by utilizing a series of lenses within the scope. The scope’s alignment can be adjusted for consideration of many natural factors like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the target. Most contemporary rifle optics have about eleven parts which are found within and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other parts. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane a scope has determines where the reticle or crosshair lies relative to the optic’s magnifying adjustments. It actually implies the reticle is situated behind or in front of the magnification lens of the optic. Selecting the most desired kind of rifle glass is dependent on what kind of shooting or hunting you plan on undertaking.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who recognize their aim point “hold over” as well as “lead” equations for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Glass Info
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. This causes the reticle to stay at the same dimensions relative to the volume of magnification being used. The final result is that the reticle measurements adapt based upon the magnification applied to shoot over greater ranges because the reticle measurements represent distinct increments which can vary with the magnification. 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 optics work for:
- Long distance forms of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots take place within much shorter proximities and ranges
- Shooters who select a clearer optic sight picture without room taken up by the larger size FFP reticle
Magnification for Scopes
The amount of magnification a scope provides is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass
A single power rifle optic will have a magnification 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 scope can not change since it is a fixed power optic.
Info on Adjustable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. It will list the zoom degree in a format such as 2-10×32. These numbers imply the magnification of the scope could be adjusted between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power manipulation is accomplished by applying the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some recommended scope powers and the distances where they could be efficiently used. Remember that high magnification scopes will not be as practical as lower magnification level scope and optics because too much magnification can be a detractor. The same concept applies to extended distances where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Glass Lens Finishing
All contemporary rifle optic lenses are coated. There are various types and qualities of glass lens finishings. Lens finish can be a crucial aspect of a rifle when looking at high end rifle optics and scope systems. The lenses are one of the most vital components of the glass given that they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses protects the lens surface area and even improves anti glare from excess sunlight and color visibility.
HD Versus ED Lenses
Some scope companies also use “HD” or high-def lens coverings that use different processes, components, polarizations, and chemical applications to draw out various color ranges and viewable definition through lenses. This high-def coating is normally used with higher density lens glass which reduces light’s opportunity to refract through the lens glass. Some scope producers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration is often noticeable over things with defined shapes as light hits the item from specific angles.
Single Finishing Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope company and how much money you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are covered or “multi” covered. This implies the lens has had numerous treatments applied to the surfaces. If a lens receives several treatments, it can establish that a company is taking multiple actions to fight different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally does not necessarily suggest the multi-coated lens will perform much better than a single layered lens. Being “better” is dependent on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Covering for Rifle Glass
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Rifle Optic Mounting Alternatives
Mounting solutions for scopes come in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually are made in quick release versions which use toss levers which allow rifle operators to rapidly install and dismount the scopes.
Hex Key Rifle Scope Rings
Normal, clamp design 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 are created for long range accuracy shooting. This type of scope mount is perfect for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. Multiple scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These kinds of mounts come in convenient for rifles which are transported a lot, to remove the scope glass from the rifle for protection, or for optics which are utilized in between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can ruin a day on the range and your costly optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a series of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for basic use rifles, unless you plan on taking your rifle on boats and are worried about the optic still performing if it goes over the side and you can still find the rifle.
Rifle Glass Gas Purging
Another component of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the scope is less affected by temp alterations and pressure distinctions from the outdoor environment which may possibly allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
