Optic Facts
Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by using a series of lenses within the scope. The scope’s alignment can be adapted to account for varied ecological elements like wind and elevation to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes have around eleven parts which are arranged internally and externally on the scope body. These parts include the rifle scope’s body, lenses, modification dials, focus rings, and other components. See all eleven parts of optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane an optic has determines where the reticle or crosshair is located in connection with the scopes zoom. It actually means the reticle is located behind or in front of the magnifying lens of the scope. Deciding upon the most effective kind of rifle glass depends upon what type of shooting you plan on undertaking.
First Focal Plane Optics
First focal plane optics (FFP) include the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the identical tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are marginal
- Experienced shooters who know their target “hold over” as well as “lead” equations for their weapon
- Shooters who don’t mind the reticle is bigger and uses up more visual sight room than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who would like a clearer optic picture with less room used up by the bigger FFP reticle
Details on Rifle Scope Zoom
The amount of zoom a scope offers is determined 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.
About Fixed Power Lens Rifle Glass
A single power rifle scope or optic comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust since it is a fixed power optic.
Variable Power Lens Scopes
Variable power rifle scopes use variable power levels. The power modification is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power Level and Range Correlation
Here are some suggested scope power levels and the ranges where they could be effectively used. Highly magnified rifle scope glass will not be as useful as lower powered glass since too much magnification can be a bad thing. The same concept applies to longer distances where the shooter needs to have sufficient power to see where to properly aim the rifle.
Rifle Optic Lens Coating
All modern-day rifle optic lenses are layered. There are various types and qualities of lens finishes. When looking at luxury rifle scope units, Lens finishing can be a significant element of defining the capability of the rifle. The glass lenses are one of the most critical pieces of the optic since they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses protects the lens surface and improves anti glare from refracted light and color discernibility.
HD Versus ED Lenses
Some rifle scope producers also use “HD” or high-definition glass coatings that employ different procedures, elements, polarizations, and chemicals to extract different colors and viewable definition through the lens. This high-def finishing is commonly used with more costly high density lens glass which lowers light’s potential to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be noticeable over objects with defined shapes as light hits the item from various angles.
Single Finish Versus Multi-Coating for Rifle Scopes
Different scope lenses can also have various finishes applied to them. All lenses generally have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It needs to have a finishing put on it so that it will be efficiently usable in numerous types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to 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 producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” coated. This suggests the lens has had numerous treatments applied to them. If a lens gets several treatments, it can indicate that a company is taking numerous steps to fight various natural factors like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also doesn’t necessarily imply the multi-coated lens is better than a single layered lens. Being “better” depends upon the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Rifle Scope Lens Finish
Water on a scope lens does not support keeping a clear sight picture through a scope at all. Many top of the line or premium optic producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Scope Mounting Alternatives
Mounting options for scopes come in a couple of choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use throw levers which enable rifle operators to rapidly install and remove the scopes.
Glass Mounts with Hex Key Rings
Basic, clamp-on style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These styles of scope mounts use double separate rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are made for long distance accuracy shooting. This type of scope mount is effective for rifle systems which require a resilient, rock solid mount which will not shift despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a faithful scope setup on a far away hunting or competition rifle that will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to stop the hex screws from wiggling out after they are mounted firmly in place. An example of these rings are the 30mm type from the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These kinds 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 similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining accuracy. These types of mounts are useful and beneficial for shooting platforms which are shipped a lot, to remove the scope from the rifle for protection, or for optics which are used between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Info on Rifle Scope Tube Gas Purging
Another element of preventing the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the glass is less impacted by temp alterations and pressure distinctions from the outdoor environment which may potentially permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
