What You Need to Know About Optics
Rifle scopes enable you to specifically align a rifle at various targets by lining up your eye with the target at range. They do this through magnification using a set of lenses within the scope. The scope’s positioning can be adjusted for the consideration of separate natural factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes have about 11 parts which are found within and outside of the scope body. These parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other components. See all eleven parts of scopes.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has establishes where the reticle or crosshair is located in connection with the optic’s magnifying adjustments. It actually implies the reticle is situated behind or in front of the magnifying lens of the scope. Picking the best form of rifle optic is dependent on what kind of hunting or shooting you anticipate undertaking.
About First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This causes the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are small
- Experienced shooters who understand their aim point “hold over” and “lead” ratios for their firearms
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. This causes the reticle to remain at the very same size relative to the quantity of magnification being used. The end result is that the reticle measurements alter based on the zoom used to shoot over lengthier distances considering that the reticle markings present distinct increments which change with the zoom. 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. These varieties of glass are useful for:
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots happen within much shorter ranges and distances
- Shooters who select a clearer optic picture without area taken up by the bigger FFP reticle
About Glass Zoom
The level of scope zoom you need on your optic depends upon the sort of shooting you plan to do. Practically every style of rifle glass gives some degree of magnification. The quantity of magnification a scope provides is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnifying level of the scope is the “power” of the opic. This means what the shooter is aiming at through the scope is amplified times the power element of what can typically be seen by human eyes.
Info on Fixed Power Lens Rifle Optics
A single power rifle optic and scope will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not change given that it is fixed.
Adjustable Power Lens Rifle Glass Facts
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will list the zoom amount in a format such as 2-10×32. These numbers imply the magnification of the scope could be adjusted between 2x and 10x power. This always includes the powers in-between 2 and 10. The power shift is achieved utilizing the power ring part of the scope near the rear of the scope by the eye bell piece.
Power Levels and Range
Here are some recommended scope powers and the distances where they may be efficiently used. High power glass will not be as effective as lower magnification glass considering that too much zoom can be a bad thing. The same goes for extended distances where the shooter needs to have enough power to see where to best aim the rifle at the target.
About Lens Finishing
All top of the line rifle optic and scope lenses are covered. Lens covering can be a crucial element of a shooting platform when looking at high end rifle optics and scope setups.
HD Versus ED Rifle Optic Lens Coatings
Some rifle scope producers will also use “HD” or high-def lense finishings which apply different processes, polarizations, aspects, and chemicals to extract separate color ranges and viewable target definition through lenses. This high-definition finish is frequently used with higher density glass which reduces light’s capability to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be obvious around objects with hard edges and outlines as light hits the object from particular angles.
About Single Finishing Versus Multi-Coating
Different scope lenses can even have different coatings applied to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a covering placed on it so that it will be optimally usable in lots of types of environments, degrees of sunshine (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope company and how much you paid for it. The scope’s maker and cost are indications of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Rifle Scope Lens Hydrophobic Covering
Water on a scope lens doesn’t support keeping a clear sight picture through a scope whatsoever. Lots of top of the line and premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the surface of the Steiner scope lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Glass Mounting Options
Installing solutions for scopes come in a couple of choices. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release versions which use manual levers which enable rifle shooters to rapidly mount and remove the glass.
Hex Key Glass Ring Mounts
Standard, 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is excellent for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used in between multiple rifles or are situationally focused.
Sealing and Gas Purging for Glass Tubes
Wetness inside your rifle optic can wreck a day on the range and your expensive optic by triggering fogging and making residue within the scope’s tube. A lot of scopes prevent humidity from entering the scope tube with a series of sealing O-rings which are water resistant. Typically, these water-resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for standard use rifles, unless you anticipate taking your rifle boating and are concerned about the scope still working if it is submerged in water and you can still salvage the gun.
Rifle Glass Gas Purging
Another element of avoiding the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less affected by climate changes and pressure distinctions from the outside environment which might potentially permit water vapor to leak 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.
