Information About Glass
Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They do this through magnification using a set of lenses inside the scope. The scope’s alignment can be adjusted for consideration of numerous natural aspects like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the target. The majority of modern-day rifle optics have about 11 parts which are arranged inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, adjustment turrets, focus rings, and other elements. See all eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the finest type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are small
- Experienced shooters who recognize their aim point “hold over” as well as “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and uses up more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnifying lens. This induces the reticle to remain at the same size relative to the level of magnification being used. The final result is that the reticle measurements shift based upon the magnification applied to shoot over longer distances considering the markings represent different increments which can vary with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These styles of glass work for:
- Long distance types of shooting where shooters have more time to make ballistic computations
- Shooting where most shots happen within shorter distances and ranges
- Shooters who desire a clearer optic sight picture without space taken up by the larger size FFP reticle
Zoom for Rifle Scopes
The quantity of magnification 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 on Fixed Single Power Lens Optics
A single power rifle optic will have 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 fluctuate because it is a fixed power optic.
Adjustable Power Lens Rifle Scope Info
Variable power rifle scopes use enhanced power. The power adjustment is handled using 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 efficiently used. Highly magnified optics will not be as beneficial as lower magnification scopes considering that too much magnification can be a bad thing. The same goes for longer ranges where the shooter needs enough power to see precisely where to best aim the rifle at the target.
Info on Lens Covering
All contemporary rifle scope lenses are coated. There are different types and qualities of glass coverings. When considering luxury rifle optics and scope devices, Lens finish can be a significant element of defining the capability of the rifle. The glass lenses are among the most significant pieces of the optic given that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses offers protection to the lens exterior as well as improves anti glare capabilities from excess sunshine and color discernibility.
ED Versus HD Glass
Some glass suppliers additionally use “HD” or high-def lens coverings which employ different processes, components, polarizations, and chemical applications to draw out separate colors and viewable definition through lenses. This HD finish is typically used with more costly high density lens glass which brings down light’s opportunity to refract through the lens glass. Some scope makers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable around objects with hard edges and outlines as light hits the item from specific angles.
Single Covering Versus Multi-Coating
Various scope lenses can even have various finishes applied to them. All lenses generally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It needs to have a finishing put on it so that it will be optimally functional in lots of types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to 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 coated lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. This means the lens has several treatments applied to the surfaces of the glass. If a lens receives several treatments, it can prove that a maker is taking several steps to fight different natural factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also does not always suggest the multi-coated lens will perform better than a single covered lens. Being “much better” depends on the maker’s lens treatment solutions and the quality of products used in building the rifle optic.
What to Know About Anti-water Finishing
Water on a lens does not assist with maintaining 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 coating.
Scope Installation Options
Installing approaches for scopes can be found in a couple of choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually come in quick release variations which use toss levers which enable rifle shooters to rapidly mount and remove the scopes.
Hex Key Rifle Optic Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope install is fine for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. If they all use a similar design mount, a number of scopes can often be switched out in the field. The quick detach design is CNC machined 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 the original sighting settings. These kinds of mounts are useful and practical for shooting platforms which are carried a lot, to take off the scope glass from the rifle for protection, or for scopes which are chosen for use between a number of rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It typically costs around $250 USD
What to Know About Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can wreck a day of shooting and your expensive optic by inducing fogging and generating residue within the scope’s tube. Most scopes protect against moisture from getting in the optical tube with a system of sealing O-rings which are water resistant. Generally, these water resistant optics 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 avoidance for basic use rifles, unless you anticipate taking your rifle aboard a watercraft and are worried about the scope still working if it goes overboard and you can still find the gun.
Rifle Glass Gas Purging
Another element of preventing the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the scope is less influenced by temperature changes and pressure variations from the outdoor environment which might possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
