Info About Optics
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through zoom by utilizing a series of lenses inside the scope. The scope’s positioning can be dialed in to account for different ecological elements 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 on the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle optics have about 11 parts which are arranged inside and on the exterior of the optic. These parts include the rifle scope’s body, lenses, elevation dials, objective focus rings, and other elements. See all eleven parts of scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the best type of rifle scope is based on what type of shooting you plan on doing.
First Focal Plane Scope Details
First focal plane glass (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are small
- Experienced shooters who know their target “hold over” and “lead” equations for their firearms
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle to the rear of the magnification lens. This causes the reticle to stay at the same dimensions in relation to the amount of zoom being used. The end result is that the reticle measurements evolve based on the magnification applied to shoot over longer distances considering the reticle measurements represent distinct increments which change with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These varieties of scopes are convenient for:
- Far away types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who want a clearer optic sight picture with less area used up by the larger sized FFP reticle
Details on Glass Magnification
The amount of magnification 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.
Fixed Power Lens Rifle Scope Info
A single power rifle optic and scope uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust given that it is set from the factory.
Adjustable Power Lens Optic Details
Variable power rifle scopes can be changed between magnification power levels. It will note the magnification amount in a format like 2-10×32. These numbers imply the magnification of the scope can be set between 2x and 10x power. This additionally utilizes the power levels in-between 2 and 10. The power adaptation is accomplished utilizing the power ring component of the scope near the rear of the scope by the eye bell piece.
Glass Power and Range Correlation
Here are some recommended scope power levels and the ranges where they may be successfully used. High power optics will not be as effective as lower magnification level scopes given that too much magnification can be a negative aspect depending on your shooting distance. The same idea relates to extended ranges where the shooter needs increased power to see precisely where to best aim the rifle at the target.
Details on Rifle Glass Lens Coverings
All top of the line rifle optic and scope lenses are layered. Lens finishing is an essential aspect of a shooting system when considering high end rifle optics and scope equipment.
HD Versus ED Glass Lens Coatings
Some glass makers will also use “HD” or high-definition lens coatings that make the most of different procedures, polarizations, components, and chemicals to extract different colors and viewable target definition through lenses. This HD coating is commonly used with greater density lens glass which brings down light’s potential to refract through the lens glass. Some scope brands use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious over items with hard shapes as light hits the item from particular angles.
Single Coating Versus Multi-Coating
Various optic lenses can likewise have various finishings used to them. All lenses generally have at least some type of treatment or finishing used to them before they are used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less advantageous 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 specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Anti-water Lens Coating
Water on a scope’s lens doesn’t support maintaining a clear sight picture through an optic at all. Lots of top of the line and premium optic makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior surfaces of the Steiner optic lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Rifle Scope Installation Choices
Mounting approaches for scopes can be found in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also normally come in quick release variations which use toss levers which enable rifle shooters to quickly mount and dismount the glass.
Scope Mounting Solutions with Hex Key Rings
Normal, clamp style 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 a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope install is perfect for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Numerous scopes can also be switched out if they all use a similar design mount. These types of mounts are convenient for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles or are situationally focused.
Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can wreck a day on the range and your highly-priced optic by triggering fogging and producing residue inside of the scope’s tube. Many scopes prevent humidity from entering the optical tube with a system of sealing O-rings which are waterproof. 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 content avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle on boats and are worried about the optic still working if it goes over the side and you can still rescue the firearm.
Gas Purged Rifle Optic Tubes
Another component of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the glass is less affected by climate alterations and pressure distinctions from the outside environment which could possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
