Optic Information
Rifle scopes allow you to precisely aim a rifle at various targets by aligning your eye with the target over a distance. They do this through zoom by employing a set of lenses within the scope. The scope’s alignment can be adapted for consideration of separate natural considerations like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle scopes have about 11 parts which are located within and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, windage dials, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has determines where the reticle or crosshair is located in connection with the scopes zoom. It literally indicates the reticle is behind or before the magnifying lens of the optic. Selecting the most ideal style of rifle scope depends on what kind of shooting or hunting you anticipate undertaking.
First Focal Plane Optic Details
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are small
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their long gun
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Far away kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most shots happen within shorter ranges and spaces
- Shooters who choose a clearer optic picture without area used up by the larger size FFP reticle
Magnification for Optics
The measure of scope magnification you need on your optic depends on the style of shooting you like to do. Just about every kind of rifle glass offers some amount of zoom. The level of magnification a scope delivers is established by the size, density, and curves of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope. This implies what the shooter is observing through the scope is magnified times the power aspect of what can usually be seen by human eyes.
Fixed Single Power Lens Rifle Optic Facts
A single power rifle optic and scope will have a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not adjust given that it is set from the factory.
Variable Power Lens Optics
Variable power rifle scopes use enhanced power. The power adjustment is performed by using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power levels and the ranges where they can be successfully used. High power rifle scope glass will not be as effective as lower powered optics since too much zoom can be a negative aspect depending on your shooting distance. The same goes for longer distances where the shooter needs adequate power to see precisely where to best aim the rifle.
About Glass Lens Finishing
All modern-day rifle scope lenses are coated. There are various types and qualities of glass lens finishes. Lens finishing can be an important aspect of a rifle when looking into high-end rifle optics and scope equipment. The lenses are among the most key components of the optic given that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses offers protection to the lens surface area and also helps with anti glare from excess light and color profiles.
ED Versus HD Optics
Some glass producers also use “HD” or high-definition lens finishings that use different procedures, polarizations, rare earth compounds, and elements to enhance different colors and viewable target visibility through lenses. This high-definition finishing is normally used with greater density lens glass which drops light’s chance to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around items with hard edges and shapes as light hits the object from certain angles.
Single Finishing Versus Multi-Coating
Various optic lenses can also have different finishes applied to them. All lenses typically have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. Because the lens isn’t simply 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 lots of kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope maker and how much money you spent for it. Both the make and cost are indications of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” covered. This indicates the lens has had multiple treatments applied to the surfaces of the glass. If a lens gets several treatments, it can establish that a maker is taking multiple actions to combat different natural aspects like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This also doesn’t necessarily indicate the multi-coated lens will perform better than a single layered lens. Being “better” is dependent on the maker’s lens treatment innovation and the quality of products used in creating the rifle scope.
Anti-water Lens Covering
Water on a scope’s lens does not help with keeping a clear sight picture through a scope whatsoever. Numerous top of the line or premium optic makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface of the Steiner glass lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Optic Installing Choices
Mounting solutions for scopes can be found 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 various types of mounts also usually are made in quick release variations which use toss levers which allow rifle operators to quickly install and dismount the optics.
Hex Key Scope Rings
Basic, clamp-on design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These forms of scope mounts use two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is exceptional for rifles which require a long lasting, unfailing mount which will not shift despite just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should get for a dedicated scope system on a long distance hunting or competition firearm which will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screw threads from backing out after they are installed safely in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly connect 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 similar design mount. These types of mounts are convenient for long guns which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles or are situationally focused.
Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by triggering fogging and producing residue within the scope’s tube. Many optics protect against humidity from entering the optical tube with a system of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness prevention for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle on a boat and are worried about the optic still performing if it goes over the side and you can still salvage the firearm.
Rifle Optic Gas Purging
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 already taken up by the gas, the scope is less influenced by temp shifts and pressure differences from the outdoor environment which may potentially enable 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.
