All About Optics
Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target by utilizing a series of lenses within the scope. The scope’s alignment can be adapted to take into account numerous natural factors like wind and elevation to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes have around 11 parts which are located inside and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. See all eleven parts of optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the best type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Glass Facts
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who recognize their aim point “hold over” and also “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. This causes the reticle to remain at the exact same overall size in connection with the level of magnification being used. The result is that the reticle dimensions alter based upon the magnification applied to shoot over lengthier distances considering that the markings represent various increments which fluctuate 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 sorts of glass are handy for:
- Far away forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who like a clearer optic picture without room taken up by the larger sized FFP reticle
Magnification for Glass
The quantity of zoom a scope offers is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Glass
A single power rifle scope will have a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not change since it is a set power scope.
About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes use enhanced power. The power modification is handled using the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power and Range Correlation
Here are some suggested scope power levels and the ranges where they can be successfully used. Keep in mind that higher magnification optics and scopes will not be as effective as lower powered optics and scopes since too much magnification can be a detractor. The very same idea relates to extended ranges where the shooter needs increased power to see exactly where to properly aim the rifle at the target.
Scope Lens Coating
All top teir rifle optic lenses are coated. Lens covering is an essential aspect of a shooting platform when purchasing high end rifle optics and scope systems.
HD Versus ED Glass Lens Coatings
Some rifle scope producers also use “HD” or high-definition lense finishes that employ different procedures, elements, chemicals, and polarizations to draw out separate color ranges and viewable target definition through lenses. This high-def finishing is often used with more costly high density lens glass which lowers light’s ability to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around things with hard outlines as light hits the object from particular angles.
Info on Single Finish Versus Multi-Coating
Various scope lenses can also have various finishings applied to them. All lenses generally have at least some kind of treatment or coating applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in numerous types of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Optic Lens Hydrophobic Coating
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish.
Alternatives for Mounting Rifle Optics on Long Guns
Installing options for scopes can be found in a couple of options. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically are made in quick release variations which use toss levers which enable rifle operators to quickly install and dismount the scopes.
Optic Mounting Solutions with Hex Key Rings
Basic, clamp-on style mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use two individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for far away accuracy shooting. This form of scope mount is ideal for rifles which require a durable, rock solid mount which will not change no matter just how much the scope is moved or abuse the rifle takes. These are the design of mounts you should have for a faithful scope setup on a reach out and touch someone hunting or tournament firearm which will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to keep the hex screws from backing out after they are installed securely in position. An example of these mounting rings are the 30mm type from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. Several scopes can also be switched out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving the original sighting settings. These kinds of mounts are useful and practical for rifles which are carried a lot, to take off the glass from the rifle for protection, or for optics which are chosen for use in between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD
What to Know About Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can wreck a day on the range and your highly-priced optic by resulting in fogging and generating residue inside of the scope’s tube. A lot of optics protect against humidity from entering the scope tube with a series of sealing O-rings which are waterproof. Usually, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for basic use rifles, unless you intend on taking your rifle boating and are concerned about the scope still working if it goes over the side and you can still find the firearm.
Details on Scope Tube Gas Purging
Another component of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the optic is less altered by temperature level alterations and pressure variations from the outside environment which could possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
