Information Rifle Glass
Rifle scopes allow you to specifically align a rifle at different targets by lining up your eye with the target at range. They do this through zoom by making use of a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account different ecological factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the target. Many modern-day rifle scopes have around 11 parts which are found within and externally on the scope. These parts include the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other components. See all eleven parts of scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the optimal type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Optics
First focal plane glass (FFP) come with the reticle before the magnifying lens. This causes the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at one hundred yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who recognize their aim point “hold over” and also “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. This induces the reticle to remain at the same overall size in connection with the volume of magnification being used. The effect is that the reticle dimensions adapt based upon the zoom used to shoot over greater distances due to the fact that the markings present various increments which change with the magnification. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular kinds of optics work for:
- Far away kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots happen within shorter distances and ranges
- Shooters who select a clearer optic sight picture with less area used up by the enlarged FFP reticle
Rifle Scope Zoom
The quantity of zoom a scope supplies is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Optic Facts
A single power rifle scope or optic uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not adjust because it is a fixed power optic.
Adjustable Power Lens Optic Info
Variable power rifle scopes have adjustable power. It will list the magnification degree in a format like 2-10×32. These numbers mean the zoom of the scope could be changed between 2x and 10x power. This additionally utilizes the power levels in-between 2 and 10. The power manipulation is achieved utilizing the power ring part of the scope near the back of the scope by the eye bell piece.
Power and Range Correlations
Here are some recommended scope power levels and the ranges where they can be effectively used. Remember that higher power scopes will not be as effective as lower magnification level optics because too much zoom can be a negative thing in certain situations. The exact same idea goes for longer ranges where the shooter needs to have increased power to see exactly where to properly aim the rifle.
Lens Finishing for Rifle Glass
All contemporary rifle scope lenses are layered. There are different types and qualities of lens finishes. When shopping for luxury rifle optics and scope setups, Lens finishing can be an essential component of a rifle. The lenses are among the most crucial parts of the glass because they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses shields the lens surface as well as helps with anti glare capabilities from excess sunshine and color exposure.
HD Versus ED Lens Coatings
Some scope makers will also use “HD” or high-def glass finishings that take advantage of different procedures, elements, polarizations, and chemical applications to enhance various color ranges and viewable target visibility through the lens. This high-def covering is normally used with increased density lens glass which lowers light’s opportunity to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be visible over things with hard edges and outlines as light hits the object from certain angles.
Single Covering Versus Multi-Coating for Glass
Different scope lenses can even have various coatings applied to them. All lenses usually have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It must have a coating placed on it so that it will be efficiently usable in many kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope company and how much money you spent paying for it. Both the make and cost are indicators of the lens quality.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has several treatments applied to them. If a lens receives multiple treatments, it can establish that a producer is taking multiple steps to combat different natural elements like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This also does not necessarily indicate the multi-coated lens will perform much better than a single coated lens. Being “better” depends on the manufacturer’s lens treatment solutions and the quality of materials used in building the rifle scope.
Anti-water Lens Finishes
Water on a scope lens does not help with retaining a clear sight picture through a scope in any way. Lots of top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior of the Steiner scope lens so the H2O particles 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.
Alternatives for Installing Rifle Scopes on Long Guns
Installing approaches for scopes are available in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also usually are made in quick release variations which use throw levers which enable rifle shooters to quickly mount and dismount the optics.
Hex Key Scope Ring Mounts
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 distance accuracy shooting. This type of scope mount is wonderful for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle. A wide range of scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping accuracy. These types of mounts come in beneficial for rifles which are moved a lot, to remove the optic from the rifle for protection, or for aiming systems which are adopted between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Info Around Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day on the range and your costly optic by causing fogging and producing residue inside of the scope tube. Many scopes protect against wetness from entering the optical tube with a system of sealing O-rings which are water resistant. Generally, these water-resistant optics can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture content prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are worried about the scope still working if it is submerged in water and you can still salvage the rifle.
Scope 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 area is already taken up by the gas, the glass is less affected by temperature changes and pressure variations from the outside environment which may potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
