What You Need to Know About Glass
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification using a series of lenses inside the scope. The scope’s positioning can be adapted to take into account various environmental things like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the target. Most modern rifle scopes have around eleven parts which are arranged within and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other parts. See all eleven parts of an optic.
About Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the finest type of rifle scope is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are marginal
- Experienced shooters who know their target “hold over” plus “lead” ratios for their long gun
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Long distance forms of shooting where shooters have more time to make ballistic computations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who prefer a clearer optic sight picture without area taken up by the enlarged FFP reticle
Scope Zoom
The amount of magnification a scope provides is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Optic Info
A single power rifle scope will have a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change given that it is a fixed power optic.
Variable Power Lens Glass Details
Variable power rifle scopes can be tweaked between magnified levels. The power modification is performed by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Scopes
Here are some advised scope power settings and the distances where they may be successfully used. Always remember that high power glass will not be as effective as lower magnification level optics due to the fact that excessive magnification can be a negative thing in certain situations. The same idea relates to extended distances where the shooter needs sufficient power to see exactly where to best aim the rifle.
About Lens Coverings
All contemporary rifle scope lenses are coated. There are various types and qualities of coverings. Lens finish can be an essential element of a rifle when contemplating luxury rifle optics and scope systems. The glass lenses are among the most significant components of the optic considering they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses shields the lens surface area as well as improves anti glare from refracted sunrays and color perception.
ED Versus HD Rifle Scopes
Some rifle scope suppliers will also use “HD” or high-def glass finishes that take advantage of different processes, chemical applications, polarizations, and aspects to draw out different colors and viewable definition through lenses. This high-definition finish is commonly used with more costly, high density glass which lowers light’s ability to refract by means of the lens glass. Some scope manufacturers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious over objects with defined outlines as light hits the item from particular angles.
Single Finishing Versus Multi-Coating for Scopes
Various optic lenses can also have various coverings applied to them. All lenses normally have at least some type of treatment or covering 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 lowering glare and other less helpful 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 manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has had several treatments applied to them. If a lens gets several treatments, it can prove that a producer is taking multiple actions to combat various natural elements like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally doesn’t always indicate the multi-coated lens will perform better than a single covered lens. Being “better” depends upon the producer’s lens treatment techniques and the quality of glass used in constructing the rifle glass.
Anti-water Lens Finishes
Water on a scope’s lens does not help with preserving a clear sight picture through an optic in any way. Many top of the line and high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface of the Steiner glass lens so the water molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Rifle Glass Installing Choices
Installing solutions for scopes are available in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically come in quick release variations which use manual levers which enable rifle shooters to quickly mount and remove the glass.
Hex Key Optic Ring Mounts
Normal, 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 created for long range accuracy shooting. This type of scope mount is great for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect it to a different rifle. Numerous scopes can also be swapped out if they all use a similar style mount. These types of mounts are handy for rifles which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle scope can mess up a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. Many scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
About Rifle Glass Tube Gas Purging
Another element of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the scope is less impacted by temp shifts and pressure distinctions from the external environment which may potentially enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
