Glass Details
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnification by using a series of lenses inside the scope. The scope’s positioning can be adapted to take into account different natural considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the target. Many modern-day rifle optics have around eleven parts which are located internally and on the exterior of the scope. These optic pieces include the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle glass.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has determines where the reticle or crosshair lies in relation to the scopes zoom. It literally means the reticle is behind or ahead of the magnification lens of the optic. Deciding upon the most suitable form of rifle glass is dependent on what sort of shooting you anticipate undertaking.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who recognize their aim point “hold over” as well as “lead” ratios for their long gun
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle behind the magnification 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 reticle measurement.
- Far away styles of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots occur within much shorter proximities and ranges
- Shooters who would like a clearer optic sight picture without area used up by the larger sized FFP reticle
Rifle Glass Magnification
The quantity of magnification a scope supplies is identified 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.
Info on Fixed Power Lens Rifle Scopes
A single power rifle scope uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not adjust considering that it is a fixed power scope.
Variable Power Lens Rifle Glass Info
Variable power rifle scopes can be adjusted between magnification levels. It will note the magnification degree in a configuration like 2-10×32. These numbers mean the zoom of the scope can be changed between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power adaptation is achieved by making use of the power ring component of the scope near the rear of the scope by the eye bell.
Scope Power and Ranges
Here are some suggested scope power settings and the ranges where they could be successfully used. Bear in mind that higher magnification scopes and optics will not be as effective as lower powered scope and optics due to the fact that too much zoom can be a negative thing in certain situations. The exact same concept applies to extended distances where the shooter needs to have increased power to see where to best aim the rifle.
About Lens Finish
All state-of-the-art rifle scope lenses are layered. Lens covering is an important aspect of a shooting system when looking into high end rifle optics and scope setups.
ED Versus HD Rifle Glass
Some glass makers even use “HD” or high-definition lense coverings which make the most of different processes, chemical applications, polarizations, and elements to draw out various colors and viewable target definition through lenses. This HD coating is often used with higher density glass which brings down light’s ability to refract through the lens glass. Some scope producers use “HD” to describe “ED” suggesting 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 is often obvious over objects with well defined shapes as light hits the item from specific angles.
Single Covering Versus Multi-Coating for Glass
Different scope lenses can even have different coatings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them before they are 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 needs to have a covering placed on it so that the lens will be efficiently usable in numerous kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope company and the amount you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Rifle Optic Lens Hydrophobic Finishing
Water on a lens does not help with preserving a clear sight picture through a scope at all. Many top of the line and military grade scope companies will coat their lenses with a hydrophobic or hydrophilic covering.
Rifle Glass Installation Choices
Installing approaches for scopes come in a couple of options. There are the standard scope rings which are separately 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 variations which use manual levers which permit rifle shooters to quickly mount and dismount the optics.
Hex Key Rifle Optic Rings
Normal, 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 a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope mount is fine for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope 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. A wide range of scopes can also be switched out if they all use a complementary style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping the original sighting settings. These types of mounts are useful and beneficial for shooting platforms which are hauled around a lot, to take off the scope from the rifle for protection, or for aiming systems which are chosen for use in between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle optic can ruin a day on the range and your pricey optic by inducing fogging and producing residue within the scope’s tube. Most optics prevent wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Typically, 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 sufficient wetness prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are worried about the optic still functioning if it is submerged in water and you can still retrieve the firearm.
Gas Purged Rifle Glass Tubes
Another element of avoiding the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the optic is less influenced by condition changes and pressure variations from the outdoor environment which could possibly allow water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
