Facts About Optics
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target at range. They do this through zoom using a series of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of separate ecological aspects like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes have about 11 parts which are found inside and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the optimal type of rifle scope depends on what type of shooting you plan to do.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are small
- Experienced shooters who recognize their aim point “hold over” as well as “lead” ratios for their long guns
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance forms of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who choose a clearer optic sight picture with less area used up by the larger size FFP reticle
Zoom for Rifle Scopes
The quantity of magnification a scope supplies is figured out 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.
Single Power Lens Rifle Scope Info
A single power rifle scope or optic will have 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 change since it is a fixed power scope.
Adjustable Power Lens Glass Info
Variable power rifle scopes have adjustable power. It will list the magnification amount in a format such as 2-10×32. These numbers suggest the zoom of the scope could be changed between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power adjustment is achieved by operating the power ring component of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Glass
Here are some suggested scope powers and the ranges where they can be effectively used. High power rifle scope glass will not be as efficient as lower magnification level scopes since too much zoom can be a bad thing. The exact same idea applies to extended ranges where the shooter needs adequate power to see precisely where to properly aim the rifle.
Lens Coating for Rifle Scopes
All modern rifle optic lenses are covered. Lens finishing can be a vital aspect of a shooting platform when buying high end rifle optics and scope equipment.
ED Versus HD Rifle Scopes
Some scope manufacturers also use “HD” or high-definition lens finishes which use different methods, polarizations, chemicals, and aspects to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Rifle Glass Lens Coating Versus Multi-Coating
Different optic lenses can even have different coverings applied to them. All lenses typically have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in many kinds of environments, degrees of light (full light VS shaded), 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 shield the lens from scratches while lowering 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 developer and the amount you spent for it. Both are indications of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” coated. This means the lens has had numerous treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can indicate that a company is taking several actions to fight various natural elements like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This additionally does not necessarily indicate the multi-coated lens is better than a single coated lens. Being “better” hinges on the maker’s lens treatment solutions and the quality of materials used in building the rifle optic.
Rifle Scope Lens Hydrophobic Finish
Water on a scope’s lens does not improve keeping a clear sight picture through an optic in any way. Lots of top of the line or high-end scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the exterior of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Scope Mounting Alternatives
Installing solutions for scopes come in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release versions which use toss levers which permit rifle shooters to quickly mount and dismount the optics.
Hex Key Rifle Glass Rings
Basic, clamp type mounting optic rings use hex head screws to install to the flattop design Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use two separate rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for far away precision shooting. This type of scope mount is excellent for rifles which need a resilient, rock solid mount which will not change no matter how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should get for a devoted scope setup on a far away hunting or competition long gun that will seldom need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to stop the hex screw threads from backing out after they are mounted firmly in position. An example of these rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. If they all use a comparable design mount, several scopes can often be swapped out. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while retaining precision. These kinds of mounts are useful and practical for rifles which are moved around a lot, to remove the scope glass from the rifle for protection, or for optics which are chosen for use in between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle optic can ruin a day of shooting and your expensive optic by bringing about fogging and developing residue inside of the scope tube. The majority of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic Tubes
Another part of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the scope is less influenced by temperature level alterations and pressure distinctions from the outdoor environment which might 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 good rifle scope to look for.
