Info Rifle Optics
Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target using a series of lenses inside the scope. The scope’s alignment can be adjusted for consideration of various environmental factors like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the target. The majority of contemporary rifle scopes have around 11 parts which are found within and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other elements. See all eleven parts of a scope.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane a scope has identifies where the reticle or crosshair lies in connection with the scopes zoom. It literally means the reticle is behind or ahead of the magnification lens of the scope. Looking for the most effective sort of rifle glass depends upon what kind of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are marginal
- Experienced shooters who recognize their aim point “hold over” as well as “lead” relationships for their long guns
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnification lens. This induces the reticle to stay at the exact same dimensions in relation to the volume of magnification being used. The final result is that the reticle measurements adjust based upon the zoom used to shoot over longer ranges given that the reticle measurements present different increments which differ with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular styles of optics are beneficial for:
- Long distance styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who select a clearer optic sight picture without area taken up by the enlarged FFP reticle
Details on Scope Magnification
The quantity of zoom a scope supplies is determined 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.
Info About Fixed Power Lens Rifle Optics
A single power rifle optic uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not adjust given that it is a fixed power optic.
Info About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use enhanced power. The power adjustment is achieved by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some recommended scope powers and the distances where they can be effectively used. High power optics will not be as effective as lower magnification level rifle scope glass due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The same idea goes for extended ranges where the shooter needs enough power to see precisely where to best aim the rifle.
Rifle Scope Lens Finishing
All modern-day rifle optic and scope lenses are coated. Lens finishing can be an important element of a shooting platform when looking into high end rifle optics and scope equipment.
About Lens Coatings – HD Versus ED
Some optic suppliers will also use “HD” or high-definition lens coatings that take advantage of various procedures, rare earth compounds, components, and polarizations to extract separate color ranges and viewable target definition through lenses. This HD coating is often used with increased density lens glass which decreases light’s chance to refract through the lens glass. Some scope producers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be visible over things with well defined outlines as light hits the object from certain angles.
Single Rifle Optic Lens Finish Versus Multi-Coating
Various scope lenses can even have various finishes applied to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many kinds of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope manufacturer and just how much you paid for it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. This implies the lens has several treatments applied to the surfaces. If a lens receives numerous treatments, it can show that a company is taking several actions to combat various environmental elements like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also does not necessarily imply the multi-coated lens will perform much better than a single layered lens. Being “much better” hinges on the manufacturer’s lens treatment solutions and the quality of materials used in developing the rifle scope.
Info on Hydrophobic Finish
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic covering.
Options for Mounting Glass on Firearms
Installing solutions for scopes are available in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use throw levers which permit rifle operators to quickly mount and dismount the scopes.
Glass Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long distance accuracy shooting. This type of scope install is fine for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types 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 switched out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely 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 maintaining precision. These types of mounts come in convenient for rifles which are hauled around a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are adopted in between numerous rifles. An example of this mount type is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day on the range and your highly-priced optic by resulting in fogging and creating residue within the scope tube. A lot of optics prevent moisture from entering the scope tube with a series of sealing O-rings which are water resistant. Generally, these water-resistant optics can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient humidity prevention for common use rifles, unless you anticipate taking your rifle aboard watercrafts and are worried about the optic still functioning if it goes overboard and you can still retrieve the gun.
What to Know About Rifle Glass Tube Gas Purging
Another element of avoiding the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is currently taken up by the gas, the glass is less affected by temp shifts and pressure variations from the outdoor environment which might possibly allow water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
