Facts About Optics
Rifle scopes enable you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by using a set of lenses within the scope. The scope’s positioning can be dialed in for consideration of different environmental aspects like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to understand precisely 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 intended point of impact. Most modern rifle scopes and optics have about eleven parts which are found inside and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other parts. See all eleven parts of scopes.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has identifies where the reticle or crosshair lies in regard to the optic’s magnifying adjustments. It literally implies the reticle is behind or in front of the magnifying lens of the optic. Picking the most desired style of rifle glass depends upon what form of shooting or hunting you intend on doing.
Info on First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are minimal
- Experienced shooters who recognize their target “hold over” as well as “lead” equations for their firearms
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle behind the zoom 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 measurement.
- Far away types of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who would like a clearer optic sight picture with less area used up by the bigger FFP reticle
Rifle Optic Magnification
The amount of magnification a scope supplies is figured out by the size, 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 Scopes
A single power rifle scope comes with a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate considering that it is set from the factory.
Adjustable Power Lens Optics
Variable power rifle scopes can be modified between magnified levels. The power change is performed using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Scopes
Here are some recommended scope powers and the ranges where they could be successfully used. High power optics will not be as beneficial as lower magnification level optics considering too much zoom can be a negative aspect depending on your shooting distance. The exact same idea applies to extended ranges where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Lens Covering for Optics
All modern rifle optic and scope lenses are covered in special coatings. There are various types and qualities of glass lens finishes. When looking at high end rifle optics and scope units, Lens coating can be a critical aspect of defining the capability of the rifle. The glass lenses are one of the most vital parts of the optic as they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface area and also helps with anti glare capabilities from refracted direct sunlight and color recognition.
Details on Rifle Optic Lens Coatings – HD Versus ED
Some scope companies will also use “HD” or high-definition lens finishings which apply different processes, chemical applications, polarizations, and components to extract a wide range of colors and viewable target definition through the lens. This HD finish is typically used with more costly high density lens glass which brings down light’s opportunity to refract through the lens glass. Some scope producers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be visible around things with hard shapes as light hits the item from various angles.
Single Scope Lens Finishing Versus Multi-Coating
Different optic lenses can also have various finishings applied to them. All lenses generally have at least some kind of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It must have a finishing put on it so that the lens will be optimally functional in many types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
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 covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are layered or “multi” covered. This indicates the lens has had several treatments applied to the surfaces. If a lens receives several treatments, it can show that a producer is taking multiple steps to fight different environmental factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This additionally doesn’t necessarily indicate the multi-coated lens is much better than a single coated lens. Being “better” is dependent on the maker’s lens treatment solutions and the quality of materials used in developing the rifle optic.
Glass Lens Anti-water Finish
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Alternatives for Installing Glass on Firearms
Mounting solutions for scopes come in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release variations which use manual levers which allow rifle shooters to quickly mount and dismount the scope.
Hex Key Optic Rings
Basic, clamp-on type mounting optic rings use hex head screws to install to the flattop style Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use a pair of independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are created for far away precision shooting. This kind of scope mount is great for rifles which are in need of a durable, unfailing mount which will not move no matter just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you want for a dedicated optics setup on a far away hunting or sniper competition rifle that will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to prevent the hex screws from wiggling out after they are mounted tightly in position. An example of these rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Several scopes can also be switched out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between multiple rifles or are situationally focused.
What to Know About Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can spoil a day of shooting and your highly-priced optic by triggering fogging and creating residue inside of the scope tube. The majority of scopes prevent wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Typically, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity avoidance for common use rifles, unless you intend on taking your rifle on your motorboat and are concerned about the scope still functioning if it goes over the side and you can still find the gun.
Gas Purged Rifle Scope Tubes
Another component of avoiding the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the glass is less altered by condition shifts and pressure distinctions from the outside environment which could potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
