Facts About Rifle Glass
Rifle scopes allow you to precisely align a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by using a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account separate ecological aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes have around eleven parts which are arranged inside and outside of the scope body. These parts consist of the rifle scope’s body, lenses, modification turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle scopes.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the best type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Scope Details
First focal plane scopes (FFP) include the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the extent of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who have an idea for their aim point “hold over” and “lead” equations for their long gun
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane scopes (SFP) feature the reticle to the rear of 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 reticle measurement.
- Long distance kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots take place within shorter distances and ranges
- Shooters who would like a clearer optic sight picture without space used up by the enlarged FFP reticle
Rifle Glass Magnification
The amount of magnification a scope supplies is determined 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 Scopes
A single power rifle optic and scope uses a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not adjust considering that it is fixed.
Info About Variable Power Lens Rifle Scopes
Variable power rifle scopes can be adjusted between magnification levels. It will list the zoom amount in a format like 2-10×32. These numbers imply the magnification of the scope could be changed between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power adaptation is accomplished using the power ring component of the scope near the rear of the scope by the eye bell piece.
Glass Power and Range Correlation
Here are some recommended scope powers and the distances where they can be effectively used. Highly magnified scopes will not be as beneficial as lower powered glass since too much zoom can be a negative aspect depending on your shooting distance. The same concept goes for longer distances where the shooter needs to have adequate power to see where to properly aim the rifle.
Lens Finishing for Scopes
All modern rifle optic lenses are layered. Lens finishing is an essential aspect of a rifle’s setup when buying high end rifle optics and scope systems.
ED Versus HD Optics
Some scope suppliers also use “HD” or high-definition lens finishings which apply various processes, rare earth compounds, components, and polarizations to draw out different color ranges and viewable target definition through lenses. This HD finish is normally used with increased density glass which brings down light’s ability to refract through the lens glass. Some scope vendors use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration may be obvious around items with well defined shapes as light hits the object from particular angles.
Single Rifle Glass Lens Coating Versus Multi-Coating
Different scope lenses can also have different coatings applied to them. All lenses typically 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 many kinds of environments, degrees of light (full VS shade), 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 protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope manufacturer and the amount you spent on it. Both are signs of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This means the lens has numerous treatments applied to the surfaces. If a lens receives numerous treatments, it can show that a manufacturer is taking several actions to combat different environmental aspects like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also doesn’t necessarily indicate the multi-coated lens will perform better than a single coated lens. Being “better” is dependent on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle glass.
Scope Lens Anti-water 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 scope makers will coat their lenses with a hydrophilic or hydrophobic coating.
Options for Installing Rifle Scopes on Firearms
Installing solutions for scopes are available in a couple of options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally can be found in quick release versions which use manual levers which enable rifle shooters to rapidly mount and dismount the glass.
Hex Key Rifle Optic Ring Mounts
Standard, 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long range accuracy shooting. This type of scope install is wonderful for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Ring Mounting Solutions
These kinds 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, multiple scopes can also be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining the original sighting settings. These types of mounts are useful and beneficial for shooting platforms which are transferred between vehicles a lot, to take off the glass from the rifle for protection, or for scopes which are employed in between several rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle scope can destroy a day of shooting and your pricey optic by triggering fogging and making residue inside of the scope’s tube. Most scopes protect against wetness from going into the optical tube with a system of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient humidity avoidance for common use rifles, unless you intend on taking your rifle on a boat and are concerned about the optic still functioning if it goes over the side and you can still find the firearm.
About Rifle Optic Tube Gas Purging
Another part of avoiding the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the glass is less influenced by temperature level shifts and pressure differences from the outside environment which might possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
