Information Rifle Glass
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s alignment can be adapted to take into account numerous ecological things like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle optics have around eleven parts which are found within and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other components. See all eleven parts of a scope.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the finest type of rifle scope depends on what type of shooting you plan on doing.
First Focal Plane Glass Details
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who recognize their aim point “hold over” as well as “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (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 styles of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within much shorter distances and ranges
- Shooters who desire a clearer optic picture with less room taken up by the enlarged FFP reticle
Details on Glass Magnification
The amount of magnification a scope offers is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Single Power Lens Optics
A single power rifle optic and scope comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not adjust given that it is a fixed power scope.
Adjustable Power Lens Scope Details
Variable power rifle scopes use variable power levels. The power modification is handled by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Scopes
Here are some advised scope powers and the ranges where they could be effectively used. Highly magnified scopes will not be as effective as lower powered rifle scope glass due to the fact that too much magnification can be a bad thing. The same concept relates to longer distances where the shooter needs to have increased power to see precisely where to properly aim the rifle at the target.
Details on Rifle Glass Lens Coverings
All current rifle glass lenses are layered. Lens covering is an essential element of a shooting platform when looking at high end rifle optics and scope setups.
HD Versus ED Rifle Scope Lens Coatings
Some scope brands also use “HD” or high-definition lens finishings which use different techniques, chemicals, elements, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Optic Lens Single Coating Versus Multi-Coating
Various optic lenses can even have various coverings applied to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finishing put on it so that it will be efficiently usable in many types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Lens Coatings
Water on an optic’s lens doesn’t help with keeping a clear sight picture through a scope in any way. Lots of top of the line or premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the surface area of the Steiner optic lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Options for Mounting Rifle Scopes on Long Guns
Mounting options for scopes come in a couple of choices. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally come in quick release variations which use toss levers which allow rifle shooters to quickly mount and dismount the glass.
Hex Key Scope Ring Mounts
Standard, clamp style 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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope mount is wonderful for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a similar style mount. These types of mounts are handy for rifles which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used between numerous rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by causing fogging and producing residue within the scope’s tube. A lot of scopes protect against wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Normally, these water resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture prevention for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle boating and are concerned about the scope still performing if it goes over the side and you can still retrieve the firearm.
Scope Gas Purging
Another component of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the optic is less impacted by temperature changes and pressure variations from the external environment which could potentially permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
