All About Glass
Rifle scopes permit you to precisely 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 series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of many environmental elements like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle scopes have around 11 parts which are located inside and on the exterior of the scope. These parts include the rifle scope’s body, lenses, adjustment turrets, focus rings, and other components. See all eleven parts of a scope.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane an optic has establishes where the reticle or crosshair is located in regard to the optic’s zoom. It actually means the reticle is located behind or before the magnifying lens of the scope. Deciding upon the most ideal kind of rifle optic depends on what form of shooting or hunting you anticipate doing.
First Focal Plane Glass
First focal plane scopes (FFP) include the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. As an example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting situations where computations are minimal
- Experienced shooters who have an idea for their target “hold over” plus “lead” equations for their firearm
- Shooters who do not mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane glass (SFP) include the reticle behind the magnifying lens. This triggers the reticle to remain at the exact same size in relation to the volume of zoom being used. The end result is that the reticle dimensions change based upon the magnification employed to shoot over greater ranges considering the reticle measurements present distinct increments which can vary with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These styles of glass are beneficial for:
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within shorter spaces and ranges
- Shooters who desire a clearer optic sight picture with less space taken up by the larger sized FFP reticle
Scope Zoom
The amount of zoom a scope provides is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Scopes
A single power rifle scope or optic comes with 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 zoom of this type of scope can not adjust because it is a fixed power optic.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes use variable power levels. The power modification is handled by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power Level and Range Correlation
Here are some advised scope power levels and the distances where they can be effectively used. Highly magnified glass will not be as efficient as lower powered scopes considering too much magnification can be a bad thing. The same relates to longer distances where the shooter needs increased power to see precisely where to best aim the rifle.
Lens Finishing for Scopes
All modern-day rifle optic and scope lenses are coated. There are various types and qualities of lens finishes. When researching high end rifle optics and scope devices, Lens coating can be a significant component of defining the rifle’s capability. The lenses are among the most important components of the glass considering that they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens surface area and also improves anti glare capabilities from refracted natural light and color exposure.
HD Versus ED Rifle Scope Lens Coatings
Some optic suppliers will also use “HD” or high-def glass finishings which employ different processes, elements, chemicals, and polarizations to enhance a wide range of colors and viewable target visibility through the lens. This HD coating is often used with greater density glass which decreases light’s ability to refract through the lens glass. Some scope producers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable around items with hard edges and outlines as light hits the object from particular angles.
Scope Lens Single Finishing Versus Multi-Coating
Different scope lenses can even have various coatings applied to them. All lenses normally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It must have a finishing applied to it so that it will be efficiently functional in numerous kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can safeguard 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 covered lens depends on the scope manufacturer and how much money you spent for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Scope Lens Anti-water Finish
Water on an optic’s lens does not improve maintaining a clear sight picture through a scope whatsoever. Many top of the line or premium scope producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner optic lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Rifle Glass Installation Options
Mounting options for scopes come in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use manual levers which enable rifle shooters to quickly mount and remove the scope.
Scope Mounting Solutions with Hex Key Rings
Basic, clamp-on style mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use a pair of separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This form of scope mount is very good for rifles which need to have a resilient, rock solid mount which will not change regardless of how much the scope is moved about or jarring the rifle takes. These are the type of mounts you really want to have for a devoted scope system on a far away scouting or sniper competition firearm which will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from wiggling out after they are installed firmly in place. An example of these rings are the 30mm type from Vortex Optics. The set typically costs around $200 USD
Rifle Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and connect it to a different rifle. Several scopes can also be switched out if they all use a compatible style mount. These types of mounts are convenient for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between several rifles or are situationally focused.
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can wreck a day of shooting and your costly optic by causing fogging and making residue within the scope’s tube. Most optics prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof. 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 more than enough moisture content prevention for standard use rifles, unless you anticipate taking your rifle on boats and are worried about the optic still functioning if it goes overboard and you can still rescue the gun.
Gas Purged Glass Tubes
Another element of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the optic is less altered by temperature changes and pressure variations from the outdoor environment which could potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
