Information About Optics
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They do this through magnifying the target by using a series of lenses within the scope. The scope’s positioning can be adapted for the consideration of numerous natural factors like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes have around 11 parts which are found within and on the exterior of the scope body. These parts consist of the rifle scope’s body, lenses, elevation turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
About Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane a scope has determines where the reticle or crosshair lies relative to the optic’s zoom. It literally implies the reticle is located behind or ahead of the magnification lens of the scope. Picking the most desired style of rifle scope depends on what kind of shooting or hunting you plan on undertaking.
Info About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are minor
- Experienced shooters who know their aim point “hold over” and “lead” ratios for their firearms
- Shooters who don’t mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Second Focal Plane Optic Details
Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots take place within much shorter ranges and spaces
- Shooters who desire a clearer optic sight picture without area taken up by the enlarged FFP reticle
Ins and Outs of Rifle Optic Magnification
The amount of zoom a scope offers is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Glass
A single power rifle optic comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate since it is a fixed power scope.
Variable Power Lens Glass
Variable power rifle scopes can be changed between magnification increments. These types of scopes will list the magnification degree in a format like 2-10×32. These numbers suggest the magnification of the scope could be changed between 2x and 10x power. This always involves the power levels in-between 2 and 10. The power manipulation is accomplished utilizing the power ring component of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some recommended scope powers and the ranges where they may be successfully used. Highly magnified rifle scope glass will not be as effective as lower magnification optics considering too much magnification can be a bad thing. The exact same idea goes for longer distances where the shooter needs to have enough power to see where to best aim the rifle.
Info on Rifle Optic Lens Coating
All modern-day rifle optic and scope lenses are layered. There are various types and qualities of glass lens finishes. Lens finishing is an important aspect of a rifle’s setup when considering high-end rifle optics and targeting systems. The glass lenses are among the most essential parts of the optic considering they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses safeguards the lens exterior and even assists with anti glare from excess sunlight and color profiles.
ED Versus HD Rifle Scopes
Some rifle glass companies will also use “HD” or high-definition lense coverings that apply different processes, rare earth compounds, elements, and polarizations to extract various colors and viewable target definition through lenses. This HD covering is often used with more costly high density lens glass which brings down light’s chance to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration may be visible over items with defined shapes as light hits the item from various angles.
Single Rifle Scope Lens Finish Versus Multi-Coating
Various scope lenses can even have different coverings applied to them. All lenses generally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in numerous kinds of environments, degrees of light (full light VS shaded), 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 safeguard the lens from scratches while reducing 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 upon the scope maker and the amount you spent paying for it. Both the manufacturer and amount are indications of the lens quality.
Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” coated. This means the lens has had several treatments applied to the surfaces. If a lens gets multiple treatments, it can show that a producer is taking multiple steps to fight different environmental aspects like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This also doesn’t always imply the multi-coated lens will perform better than a single coated lens. Being “much better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Finishes
Water on an optical lens doesn’t support maintaining a clear sight picture through an optic in any way. Numerous top of the line and high-end scope producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface area of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Glass Installation Choices
Installing approaches for scopes are available in a few options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually can be found in quick release versions which use toss levers which permit rifle operators to quickly install and dismount the scope.
Rifle Optic Mounts with Hex Key Rings
Normal, clamp style 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 two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope install is wonderful for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can also be swapped on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining the original sighting settings. These types of mounts are useful and beneficial for rifles which are moved around a lot, to remove the scope glass from the rifle for protection, or for scopes which are employed between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your highly-priced optic by inducing fogging and developing residue inside of the scope tube. Most scopes prevent humidity from going into the scope tube with a series of sealing O-rings which are waterproof. Typically, these scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture avoidance for common use rifles, unless you intend on taking your rifle aboard watercrafts and are concerned about the optic still functioning if it goes over the side and you can still recover the firearm.
Scope Gas Purging
Another component of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the scope is less impacted by climate changes and pressure distinctions from the external environment which may possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
