Glass Details
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by utilizing a series of lenses within the scope. The scope’s alignment can be dialed in to account for many natural factors like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes and optics have about 11 parts which are arranged within and outside of the optic. These parts consist of the rifle scope’s body, lenses, adjustment turrets, focus rings, and other components. See all eleven parts of optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has decides where the reticle or crosshair is located in relation to the scopes magnification. It simply suggests the reticle is located behind or in front of the magnifying lens of the optic. Considering the very best sort of rifle glass depends on what sort of shooting you anticipate undertaking.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who understand their aim point “hold over” plus “lead” correlations for their long gun
- Shooters who don’t mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of 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.
- Far away kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots happen within much shorter ranges and proximities
- Shooters who prefer a clearer optic picture with less room taken up by the bigger FFP reticle
Rifle Glass Magnification
The amount of scope zoom you need is based on the sort of shooting you want to do. Almost every type of rifle scope offers some degree of zoom. The quantity of zoom a scope delivers is established by the dimension, density, and curves of the lenses inside of the rifle scope. The zoom of the optic is the “power” of the scope. This indicates what the shooter is checking out through the scope is magnified times the power factor of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Glass
A single power rifle scope comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate considering that it is a set power scope.
Variable Power Lens Scope Facts
Variable power rifle scopes can be modified between magnified levels. The power modification is achieved by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power settings and the distances where they could be effectively used. Bear in mind that higher magnification scopes and optics will not be as practical as lower powered scope and optics due to the fact that too much zoom can be a negative thing in certain situations. The same idea applies to extended distances where the shooter needs increased power to see where to properly aim the rifle.
About Glass Lens Finishing
All current rifle optic lenses are coated. Lens coating can be an essential aspect of a shooting system when thinking about high end rifle optics and scope systems.
HD Versus ED Rifle Scope Lens Coatings
Some rifle glass makers also use “HD” or high-def lens coverings that apply different procedures, elements, rare earth compounds, and polarizations to extract various color ranges and viewable target definition through the lens. This high-definition finish is normally used with more costly high density glass which brings down light’s ability to refract by means of the lens glass. Some scope manufacturers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be obvious over items with hard edges and shapes as light hits the item from certain angles.
What to Know About Single Covering Versus Multi-Coating
Various optic lenses can likewise have various finishings applied to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope manufacturer and just how much you spent for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope producers 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 technology and the quality of products used in building the rifle scope.
Hydrophobic Coating for Rifle Scopes
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 makers will coat their lenses with a hydrophobic or hydrophilic anti-water coating.
Rifle Glass Installation Alternatives
Installing options for scopes can be found in a few choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically come in quick release versions which use throw levers which permit rifle operators to rapidly install and dismount the scopes.
Hex Key Optic Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different 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 mount is great for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect it to a different rifle. Several scopes can even be swapped out if they all use a similar design mount. These types of mounts come in handy for rifle platforms which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between multiple rifles or are situationally focused.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle scope can wreck a day on the range and your costly optic by causing fogging and producing residue inside of the scope tube. Many optics protect against wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Normally, these scopes can be submerged underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture prevention for standard use rifles, unless you plan on taking your rifle sailing and are worried about the optic still working if it goes over the side and you can still salvage the firearm.
Gas Purged Rifle Optic Tubes
Another component of preventing the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the optic is less impacted by temperature changes and pressure variations from the outdoor environment which may potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
