Info About Glass
Rifle scopes enable you to specifically aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by making use of a series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of various environmental things like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes have around 11 parts which are found internally and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane an optic has identifies where the reticle or crosshair is located in regard to the scopes zoom. It actually suggests the reticle is situated behind or in front of the magnifying lens of the optic. Picking out the very best form of rifle glass depends on what sort of shooting or hunting you plan on doing.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are minimal
- Experienced shooters who recognize their aim point “hold over” and also “lead” relationships for their firearm
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who would like a clearer optic sight picture with less space used up by the enlarged FFP reticle
Zoom for Rifle Scopes
The quantity of zoom a scope provides is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Glass
A single power rifle optic and scope uses a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate since it is a fixed power scope.
Adjustable Power Lens Rifle Scope Facts
Variable power rifle scopes can be modified between magnified settings. The power adjustment is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Optics
Here are some advised scope power settings and the ranges where they may be effectively used. High power optics will not be as efficient as lower magnification glass given that too much zoom can be a negative aspect depending on your shooting distance. The exact same idea relates to extended ranges where the shooter needs increased power to see exactly where to properly aim the rifle.
Details on Lens Covering
All modern rifle optic and scope lenses are coated. There are various types and qualities of lens coatings. When considering high end rifle optics and scope systems, Lens finishing can be a significant element of defining the capability of the rifle. The glass lenses are one of the most important parts of the glass given that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses shields the lens surface and also improves anti glare from refracted direct sunlight and color perception.
ED Versus HD Rifle Scopes
Some glass suppliers will also use “HD” or high-def lens finishings which make the most of different processes, rare earth compounds, polarizations, and components to extract a wide range of color ranges and viewable target visibility through lenses. This high-def finish is commonly used with greater density lens glass which lowers light’s capability to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration may be visible around objects with defined outlines as light hits the object from certain angles.
Single Finishing Versus Multi-Coating for Rifle Optics
Different optic lenses can even 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. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It must have a covering applied to it so that it will be optimally usable in numerous types of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can preserve 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 covered lens depends on the scope producer and the amount you spent for it. Both are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. This implies the lens has multiple treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can establish that a company is taking numerous steps to fight different environmental elements like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This also doesn’t always suggest the multi-coated lens is better than a single covered lens. Being “better” hinges on the manufacturer’s lens treatment techniques and the quality of materials used in creating the rifle optic.
Hydrophobic Rifle Scope Lens Finish
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Options for Mounting Scopes on Long Guns
Installing options for scopes can be found in a few options. There are the standard scope rings which are individually 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 variations which use manual levers which allow rifle shooters to rapidly install and dismount the scope.
Hex Key Optic Ring Mounts
Standard, clamp design 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 two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long range precision shooting. This type of scope mount is fine for rifles which require a resilient, sound mounting solution 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 rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can often be switched on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining precision. These kinds of mounts are useful and convenient for rifles which are shipped a lot, to take off the scope glass from the rifle for protection, or for scopes which are chosen for use between multiple rifles. An example of this mount style is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Details on Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. The majority of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Rifle Glass Tube Gas Purging
Another element of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the optic is less influenced by climate alterations and pressure differences from the outdoor environment which could potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
