What You Need to Know About Optics
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target over a range. They do this through zoom by utilizing a series of lenses inside the scope. The scope’s positioning can be dialed in to account for various environmental factors like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes and optics have around 11 parts which are arranged within and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other elements. See all eleven parts of an optic.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the perfect type of rifle scope depends on what type of shooting you plan to do.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based on the level of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are small
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” correlations for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within much shorter ranges and distances
- Shooters who desire a clearer optic picture with less area taken up by the larger sized FFP reticle
About Optic Magnification
The amount of scope zoom you need on your glass depends upon the type of shooting you like to do. Virtually every kind of rifle optic supplies some level of magnification. The level of zoom a scope supplies is identified by the diameter, density, and curves of the lens glass within the rifle optic. The magnifying level of the scope is the “power” of the glass. This indicates what the shooter is observing through the scope is amplified times the power aspect of what can normally be seen by human eyes.
About Single Power Lens Rifle Optics
A single power rifle 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 kind of scope can not fluctuate because it is a fixed power optic.
Adjustable Power Lens Scope Info
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will list the zoom amount in a configuration like 2-10×32. These numbers suggest the zoom of the scope can be adjusted in between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power shift is achieved 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 Ranges
Here are some recommended scope power settings and the ranges where they may be efficiently used. High power rifle scope glass will not be as effective as lower magnification level rifle scope glass because too much magnification can be a bad thing. The very same idea applies to longer distances where the shooter needs to have increased power to see where to best aim the rifle.
Details on Lens Coverings
All contemporary rifle scope and optic lenses are layered. There are different types and qualities of glass lens coverings. Lens covering is an essential element of a rifle’s setup when thinking about luxury rifle optics and scope systems. The glass lenses are among the most vital pieces of the optic due to the fact that they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses shields the lens surface as well as improves anti glare from excess daylight and color exposure.
Info on Rifle Optic Lens Coatings – HD Versus ED
Some rifle scope manufacturers also use “HD” or high-def lense coverings which employ various processes, polarizations, chemicals, and elements to draw out separate color ranges and viewable target visibility through lenses. This high-definition covering is typically used with more costly high density glass which drops light’s ability to refract through the lens glass. Some scope producers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration is often obvious around things with hard edges and shapes as light hits the item from particular angles.
Single Finish Versus Multi-Coating for Rifle Scopes
Various scope lenses can even have various coatings applied to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in lots of kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. 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 optic. The quality of a single coated lens depends upon the scope manufacturer and just how much you spent on it. Both the manufacturer and amount are signs of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Anti-water Glass Lens Covering
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic coating.
Choices for Installing Scopes on Firearms
Installing solutions for scopes can be found in a few options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally can be found in quick release versions which use manual levers which allow rifle operators to rapidly install and remove the scopes.
Rifle Glass Mounting Solutions with Hex Key Rings
Normal, clamp design 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 a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope mount is wonderful for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. Several scopes can also be switched out if they all use a complementary designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining accuracy. These types of mounts come in beneficial for rifles which are moved around a lot, to remove the scope glass from the rifle for protection, or for scopes which are utilized in between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can destroy a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. A lot of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another part of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the glass is less altered by climate changes and pressure distinctions from the external environment which might possibly permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
