What You Need to Know About Glass
Rifle scopes permit you to exactly aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnification by making use of a set of lenses inside the scope. The scope’s positioning can be dialed in for consideration of many ecological elements like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle optics have about eleven parts which are located inside and outside of the optic. These parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle scopes.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the finest type of rifle glass depends on what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are very little
- Experienced shooters who understand their aim point “hold over” and “lead” relationships for their long gun
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane glass (SFP) include the reticle to the rear of the magnification lens. This causes the reticle to remain at the same dimensions relative to the quantity of zoom being used. The effect is that the reticle dimensions alter based upon the zoom employed to shoot over greater distances due to the fact that the markings represent various increments which differ with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These varieties of scopes are useful for:
- Long distance styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who desire a clearer optic sight picture without room taken up by the larger size FFP reticle
Zoom for Optics
The amount of zoom 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 Power Lens Scope Details
A single power rifle optic and scope comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust given that it is a fixed power scope.
Adjustable Power Lens Scopes
Variable power rifle scopes use enhanced power. The power modification is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Scope Power and Range Correlation
Here are some advised scope power levels and the distances where they could be efficiently used. Bear in mind that higher power optics and scopes will not be as effective as lower powered optics and scopes because too much magnification can be a bad thing. The very same idea relates to extended ranges where the shooter needs enough power to see exactly where to best aim the rifle.
Info on Lens Coverings
All present day rifle optic lenses are coated. Lens covering is a significant aspect of a shooting platform when buying high end rifle optics and scope equipment.
Info on Rifle Optic Lens Coatings – HD Versus ED
Some rifle scope suppliers also use “HD” or high-definition glass coverings which apply various procedures, polarizations, components, and chemicals to enhance different color ranges and viewable target visibility through lenses. This HD coating is frequently used with more costly high density glass which reduces light’s capability to refract through the lens glass. Some scope manufacturers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable over things with hard outlines as light hits the object from certain angles.
Glass Lens Single Finish Versus Multi-Coating
Different optic lenses can also have different coatings applied to them. All lenses usually have at least some type of treatment or covering applied to them before being used in a rifle scope or optic assembly. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in numerous types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This indicates the lens has multiple treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can show that a company is taking numerous actions to fight various environmental factors like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally does not always suggest the multi-coated lens is better than a single layered lens. Being “better” hinges on the producer’s lens treatment techniques and the quality of materials used in constructing the rifle optic.
About Anti-water Finish
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic covering.
Glass Installing Alternatives
Installing approaches for scopes can be found in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally are made in quick release versions which use toss levers which enable rifle operators to quickly mount and remove the scopes.
Rifle Scope Mounts with Hex Key Rings
Standard, clamp-on style mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use double independent rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This kind of scope mount is effective for rifles which are in need of a long lasting, unfailing mount which will not move regardless of just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should get for a faithful optics setup on a far away scouting or competitors long gun which will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screws from backing out after they are mounted safely in place. An example of these rings are the 30mm style from Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Several scopes can also be switched out if they all use a similar style mount. These types of mounts come in handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles.
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle glass can destroy a day on the range and your pricey optic by inducing fogging and producing residue within the scope tube. Most scopes protect against humidity from going into the optical tube with a system of sealing O-rings which are water resistant. Usually, these water resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness avoidance for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are concerned about the scope still functioning if it is submerged in water and you can still salvage the firearm.
Gas Purged Rifle Scope Tubes
Another part of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less altered by climate shifts and pressure variations from the external environment which could potentially allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
