What You Need to Know About Optics
Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by making use of a series of lenses inside the scope. The scope’s alignment can be dialed in to account for numerous natural factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have about eleven parts which are arranged internally and on the exterior of the scope. These parts include the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other elements. Learn about the eleven parts of rifle optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has establishes where the reticle or crosshair lies in relation to the scopes magnifying adjustments. It actually means the reticle is located behind or ahead of the magnification lens of the scope. Deciding upon the most effective form of rifle optic is based upon what kind of shooting or hunting you plan on doing.
First Focal Plane Scope Info
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are low
- Experienced shooters who have an idea for their target “hold over” as well as “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the zoom 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 forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots happen within much shorter ranges and distances
- Shooters who desire a clearer optic sight picture without room used up by the enlarged FFP reticle
Magnification for Rifle Scopes
The measure of scope zoom you need on your optic depends on the form of shooting you choose to do. Nearly every style of rifle scope offers some amount of zoom. The amount of zoom a scope supplies is established by the diameter, density, and curves of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the opic. This means what the shooter is observing through the scope is amplified times the power element of what can typically be seen by human eyes.
Info About Single Power Lens Rifle Scopes
A single power rifle optic or scope comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change because it is a set power scope.
Variable Power Lens Scope Details
Variable power rifle scopes can be modified between magnified settings. The power change is achieved 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 powers and the distances where they can be efficiently used. Keep in mind that higher magnification optics will not be as efficient as lower powered scope and optics because excessive magnification can be a detractor. The same concept applies to extended ranges where the shooter needs to have adequate power to see where to best aim the rifle.
Lens Finish for Rifle Scopes
All current rifle optic and scope lenses are covered. Lens coating can be a vital aspect of a shooting platform when purchasing high end rifle optics and scope systems.
HD Versus ED Lens Coatings
Some scope companies even use “HD” or high-definition lens finishes which use various procedures, polarizations, elements, and chemicals to enhance numerous colors and viewable definition through the lens. This HD coating is often used with greater density lens glass which brings down light’s ability to refract through the lens glass. Some scope producers use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration can be obvious over things with hard edges and outlines as light hits the object from specific angles.
Single Scope Lens Covering Versus Multi-Coating
Various optic lenses can also have various coatings used to them. All lenses typically have at least some type of treatment or covering applied to them before being used in a rifle scope or optic.
This lens treatment can protect 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 layered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Anti-water Covering for Rifle Optics
Water on an optical lens does not support retaining a clear sight picture through an optic in any way. Many top of the line and premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the exterior of the Steiner glass lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Rifle Glass on Long Guns
Mounting solutions for scopes can be found in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release versions which use toss levers which permit rifle operators to rapidly install and remove the glass.
Hex Key Rifle Optic Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope mount is excellent for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping the original sighting settings. These kinds of mounts are useful and handy for shooting platforms which are transferred a lot, to take off the scope from the rifle for protection, or for optics which are employed in between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
About Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can wreck a day of shooting and your expensive optic by causing fogging and developing residue within the scope tube. A lot of optics prevent moisture from going into the scope tube with a series of sealing O-rings which are water resistant. Generally, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of humidity prevention for standard use rifles, unless you intend on taking your rifle sailing and are concerned about the optic still functioning if it is submerged in water and you can still retrieve the gun.
Rifle Optic Gas Purging
Another component of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the glass is less influenced by temperature alterations and pressure distinctions from the outside environment which could potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
