What You Need to Know About Rifle Glass
Rifle scopes allow you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by employing a set of lenses within the scope. The scope’s positioning can be adapted to account for different environmental considerations like wind and elevation increases or 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 scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have around eleven parts which are located internally and externally on the scope body. These optic pieces include the rifle scope’s body, lenses, modification turrets, focus rings, and other parts. See all eleven parts of optics.
About Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form 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 situated behind or in front of the magnification lens of the scope. Choosing the most ideal kind of rifle glass is based on what form of shooting or hunting you anticipate undertaking.
About First Focal Plane Scopes
First focal plane scopes (FFP) include the reticle before the magnification lens. This causes the reticle to increase in size based on the amount of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified range. As an example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are small
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” correlations for their long gun
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight area than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (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 reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter proximities and ranges
- Shooters who desire a clearer optic picture without room taken up by the enlarged FFP reticle
Optic Magnification
The level of scope zoom you need on your optic is based on the type of shooting you desire to do. Almost every kind of rifle scope provides some degree of magnification. The amount of zoom a scope offers is determined by the dimension, density, and curvatures of the lens glass within the rifle optic. The zoom of the optic is the “power” of the glass. This denotes what the shooter is observing through the scope is magnified times the power factor of what can typically be seen by human eyes.
Fixed Single Power Lens Rifle Scopes
A single power rifle scope comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change considering that it is a set power scope.
About Adjustable Power Lens Optics
Variable power rifle scopes can be changed between magnification increments. It will note the zoom degree in a configuration such as 2-10×32. These numbers suggest the zoom of the scope could be adjusted between 2x and 10x power. This also utilizes the power levels in-between 2 and 10. The power manipulation is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Scopes
Here are some advised scope powers and the distances where they may be successfully used. Always remember that higher magnification scopes and optics will not be as effective as lower magnification level optics due to the fact that too much magnification can be a bad thing. The same idea relates to longer distances where the shooter needs increased power to see where to best aim the rifle at the target.
Rifle Glass Lens Finishing
All modern-day rifle optic lenses are layered. There are various types and qualities of coatings. When looking at high end rifle targeting devices, Lens finish can be a critical component of a rifle. The glass lenses are among the most crucial components of the optic given that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface and even assists with anti glare from refracted daylight and color recognition.
Details on Lens Coatings – HD Versus ED
Some optic companies will also use “HD” or high-def lense coatings which take advantage of various procedures, components, compounds, and polarizations to enhance different colors and viewable definition through lenses. This high-definition coating is commonly used with more costly, high density glass which reduces light’s potential to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible around things with hard shapes as light hits the item from certain angles.
Single Finishing Versus Multi-Coating for Rifle Glass
Various optic lenses can likewise have different coverings applied to them. All lenses normally have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and boosting 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 scope. The quality of a single covered lens depends upon the scope maker and how much you spent on it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Glass Lens Hydrophobic Coating
Water on a lens does not help with preserving 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 hydrophilic or hydrophobic covering.
Rifle Scope Installing Options
Installing approaches for scopes come in a couple of choices. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release versions which use throw levers which enable rifle operators to rapidly mount and dismount the scopes.
Hex Key Glass Rings
Standard, clamp design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use two independent rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are created for long distance precision shooting. This form of scope mount is great for rifles which require a resilient, rock solid mount which will not shift regardless of just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should have for a dedicated scope system on a reach out and touch someone hunting or interdiction rifle that will hardly ever need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to keep the hex screw threads from wiggling out after they are mounted tightly in position. An example of these mounting rings are the 30mm type from Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Multiple scopes can even be switched out if they all use a similar design mount. These types of mounts are handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used in between several rifles.
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle glass can mess up a day on the range and your pricey optic by causing fogging and developing residue within the scope’s tube. Many scopes prevent humidity from getting in the optical tube with a series of sealing O-rings which are waterproof. Generally, these optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness prevention for basic use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are concerned about the scope still performing if it falls overboard and you can still retrieve the rifle.
Gas Purged Rifle Scope Tubes
Another element of preventing the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the scope is less affected by temperature level shifts and pressure differences from the external environment which may possibly allow water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
