Information About Rifle Glass
Rifle scopes permit you to precisely aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnifying the target by using a series of lenses inside the scope. The scope’s alignment can be dialed in to take into account various environmental considerations like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle scopes have around 11 parts which are arranged inside and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, adjustment dials, focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the best type of rifle glass depends on what type of shooting you plan to do.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are small
- Experienced shooters who have an idea for their target “hold over” and “lead” equations for their firearms
- Shooters who do not mind the reticle is bigger and takes up more visual sight room than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who prefer a clearer optic sight picture with less room used up by the larger size FFP reticle
Rifle Scope Zoom
The level of scope magnification you need on your optic is based on the type of shooting you choose to do. Just about every style of rifle glass supplies some level of zoom. The amount of zoom a scope gives is identified by the size, thickness, and curvatures of the lenses within the rifle scope. The magnifying level of the optic is the “power” of the scope. This signifies what the shooter is observing through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Fixed Single Power Lens Optic Details
A single power rifle scope or optic comes with a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust since it is fixed.
Variable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a format like 2-10×32. These numbers suggest the magnification of the scope could be changed in between 2x and 10x power. This always includes the powers in-between 2 and 10. The power modification is achieved by operating the power ring component of the scope near the rear of the scope by the eye bell piece.
Power and Range Correlations
Here are some advised scope power settings and the distances where they may be efficiently used. Consider that higher magnification scopes and optics will not be as efficient as lower magnification level optics and scopes due to the fact that increased zoom can be a bad thing. The same idea goes for extended distances where the shooter needs adequate power to see precisely where to best aim the rifle.
Lens Finishing for Rifle Scopes
All modern-day rifle scope lenses are layered. There are various types and qualities of glass lens finishings. Lens finishing can be a crucial aspect of a rifle’s setup when thinking of luxury rifle optics and targeting equipment. The lenses are among the most crucial pieces of the optic as they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses protects the lens exterior as well as helps with anti glare from refracted sunshine and color recognition.
Info on Lens Coatings – HD Versus ED
Some glass manufacturers additionally use “HD” or high-definition lense coatings that make the most of different processes, polarizations, aspects, and chemicals to draw out separate colors and viewable target definition through lenses. This high-def coating is commonly used with more costly high density glass which decreases light’s capability to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious over objects with well defined shapes as light hits the object from particular angles.
Single Covering Versus Multi-Coating for Scopes
Various scope lenses can also have different finishes applied to them. All lenses normally have at least some kind of treatment or coating applied to them before being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in many types of environments, degrees of light (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can preserve 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 designer and how much money you spent paying for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are covered or “multi” coated. This implies the lens has had several treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can establish that a maker is taking several actions to fight different environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This also does not necessarily suggest the multi-coated lens will perform better than a single layered lens. Being “better” is dependent on the maker’s lens treatment techniques and the quality of materials used in developing the rifle scope.
Rifle Optic Lens Anti-water Finishing
Water on an optic’s lens doesn’t improve preserving a clear sight picture through an optic in any way. Many top of the line or premium optic producers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner glass lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Rifle Glass Installing Options
Mounting options for scopes can be found in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally come in quick release variations which use toss levers which allow rifle operators to rapidly mount and dismount the optics.
Rifle Glass Mounting Solutions with Hex Key Rings
Normal, clamp style 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 a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope mount is wonderful for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounts with Quick-Release Cantilever Rings
These types 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, several scopes can also be swapped out on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving accuracy. These types of mounts are useful and practical for shooting platforms which are transported a lot, to remove the glass from the rifle for protection, or for scopes which are chosen for use in between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle scope can wreck a day of shooting and your costly optic by inducing fogging and creating residue inside of the scope’s tube. The majority of optics prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant. Generally, these scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture prevention for basic use rifles, unless you plan on taking your rifle aboard watercrafts and are concerned about the optic still working if it goes overboard and you can still recover the gun.
Rifle Scope Gas Purging
Another element of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the glass is less altered by condition alterations and pressure differences from the outdoor 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.
