Facts About Rifle Optics
Rifle scopes allow you to precisely align a rifle at various targets by lining up your eye with the target over a distance. They do this through zoom by using a series of lenses within the scope. The scope’s positioning can be adapted for the consideration of numerous environmental factors like wind and elevation increases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes and optics have about 11 parts which are arranged within and on the exterior of the scope body. These scope parts consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the perfect type of rifle glass is based around what type of shooting you plan on doing.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are small
- Experienced shooters who know their target “hold over” plus “lead” ratios for their long guns
- Shooters who do not mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle behind the magnification lens. This triggers the reticle to remain at the very same size relative to the level of magnification being used. The end result is that the reticle measurements evolve based upon the zoom applied to shoot over longer ranges because the markings present distinct increments which change with the magnification level. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These varieties of optics are handy for:
- Long distance forms of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within much shorter distances and ranges
- Shooters who choose a clearer optic sight picture without area taken up by the bigger FFP reticle
Optic Zoom
The quantity of zoom a scope offers 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.
Info About Single Power Lens Optics
A single power rifle scope uses 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 type of scope can not fluctuate since it is fixed.
Adjustable Power Lens Glass Details
Variable power rifle scopes use variable power levels. The power change is handled by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Glass
Here are some suggested scope power settings and the ranges where they could be effectively used. Keep in mind that high power glass will not be as effective as lower powered scopes due to the fact that increased magnification can be a bad thing. The very same idea goes for longer ranges where the shooter needs increased power to see exactly where to properly aim the rifle at the target.
About Lens Finishes
All cutting-edge rifle optic lenses are coated. Lens finish is a vital element of a shooting platform when purchasing high end rifle optics and scope setups.
HD Versus ED Glass Lens Coatings
Some optic makers even use “HD” or high-definition lens coatings which employ different processes, components, polarizations, and chemicals to enhance separate color ranges and viewable target visibility through lenses. This HD finish is normally used with higher density lens glass which drops light’s opportunity to refract through the lens glass. Some scope brands use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration can be obvious around objects with hard edges and shapes as light hits the item from various angles.
Glass Lens Single Finish Versus Multi-Coating
Different scope lenses can even have various coatings applied to them. All lenses usually have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It must have a finishing applied to it so that it will be optimally usable in lots of kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope maker and how much you paid for it. Both the make and cost are indications of the lens quality.
Some scope manufacturers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Anti-water Lens Coatings
Water on a scope lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line and premium optic producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior surfaces of the Steiner glass lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Glass Installation Alternatives
Mounting solutions for scopes come in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually come in quick release versions which use toss levers which allow rifle shooters to quickly mount and remove the scope.
Hex Key Glass Ring Mounting Solutions
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 a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope install is perfect for rifles which require 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 Scope Rings
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, a number of scopes can often be swapped on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining precision. These types of mounts come in convenient for rifles which are moved a lot, to remove the scope from the rifle for protection, or for scopes which are used in between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your costly optic by triggering fogging and creating residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Glass Tubes
Another component 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 glass is less affected by temperature level changes and pressure distinctions from the external environment which might potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
