Information Optics
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of many environmental things like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle optics have around eleven parts which are found internally and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, windage turrets, objective focus rings, and other parts. Learn about the eleven parts of optics.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has determines where the reticle or crosshair lies in connection with the scopes zoom. It simply indicates the reticle is behind or ahead of the magnification lens of the scope. Picking out the best kind of rifle glass depends on what style of shooting you intend on doing.
Info About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who know their aim point “hold over” and “lead” relationships for their long gun
- Shooters who don’t mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane optics (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who select a clearer optic picture without space taken up by the larger sized FFP reticle
Zoom for Rifle Optics
The amount of magnification a scope provides is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification 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 while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate given that it is fixed.
Variable Power Lens Optics
Variable power rifle scopes can be changed between magnification levels. These types of scopes will note the magnification degree in a configuration like 2-10×32. These numbers suggest the magnification of the scope could be adjusted in between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power manipulation is achieved by working with the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope powers and the ranges where they could be efficiently used. High power scopes will not be as effective as lower magnification level scopes since too much magnification can be a negative aspect depending on your shooting distance. The same concept relates to extended distances where the shooter needs to have increased power to see exactly where to properly aim the rifle at the target.
About Rifle Glass Lens Coating
All modern rifle scope and optic lenses are covered in special coatings. There are different types and qualities of lens coatings. When researching luxury rifle targeting devices, Lens covering can be a very important aspect of defining the capability of the rifle. The lenses are one of the most significant components of the scope considering they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses protects the lens surface area and even assists with anti glare capabilities from refracted sunrays and color discernibility.
HD Versus ED Lenses
Some scope makers also use “HD” or high-def lens coverings which take advantage of various procedures, components, polarizations, and chemicals to enhance various color ranges and viewable definition through the lens. This high-definition finishing is commonly used with greater density lens glass which lowers light’s opportunity to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration may be noticeable over items with hard outlines as light hits the item from particular angles.
Single Scope Lens Finishing Versus Multi-Coating
Various optic lenses can also have different coverings used to them. All lenses normally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while reducing 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 on the scope maker and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are covered or “multi” covered. This implies the lens has had several treatments applied to the surfaces. If a lens receives several treatments, it can establish that a maker is taking numerous steps to combat various natural factors like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally does not necessarily suggest the multi-coated lens is much better than a single layered lens. Being “better” depends upon the manufacturer’s lens treatment techniques and the quality of materials used in creating the rifle optic.
Hydrophobic Optic Lens Finish
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish.
Choices for Installing Rifle Glass on Long Guns
Installing options for scopes can be found in a few options. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use manual levers which permit rifle operators to quickly mount and dismount the scopes.
Glass Mounting Solutions with Hex Key Rings
Standard, clamp type mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These kinds of scope mounts use two detached rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This kind of scope mount is exceptional for rifle systems which require a long lasting, rock solid mount which will not move no matter just how much the scope is moved or jarring the rifle takes. These are the design of mounts you want for a devoted optics system on a far away scouting or competitors rifle that will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used to keep the hex screws from backing out after they are installed firmly in place. An example of these rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Scope Rings
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 switched out if they all use a complementary designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping the original sighting settings. These types of mounts are useful and handy for rifles which are shipped a lot, to take off the optic from the rifle for protection, or for scopes which are employed between numerous rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. Many scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic Tubes
Another part of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the scope is less altered by climate shifts and pressure differences from the outside environment which might potentially permit 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.
