Rifle Glass Information
Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target over a distance. They do this through magnification by making use of a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account different ecological elements like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes and optics have around eleven parts which are located internally and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, elevation dials, objective focus rings, and other components. See all eleven parts of a rifle scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the optimal type of rifle glass is based on what type of shooting you plan on doing.
Info on First Focal Plane Scopes
First focal plane optics (FFP) come with the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based upon the amount of zoom being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at 100 yards without “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who know their target “hold over” as well as “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include 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 additional time to make ballistic calculations
- Shooting where most shots occur within much shorter spaces and ranges
- Shooters who want a clearer optic sight picture without area used up by the enlarged FFP reticle
Magnification for Rifle Scopes
The level of scope zoom you require depends on the style of shooting you like to do. Virtually every kind of rifle glass offers some level of magnification. The quantity of magnification a scope offers is determined by the size, thickness, and curvatures of the lens glass within the rifle optic. The zoom of the optic is the “power” of the opic. This suggests what the shooter is looking at through the scope is magnified times the power aspect of what can normally be seen by human eyes.
Fixed Single Power Lens Glass
A single power rifle optic uses a magnification 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 type of optic can not change considering that it is a set power scope.
Variable Power Lens Rifle Optic Details
Variable power rifle scopes can be tweaked between magnified levels. The power change is performed by using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power and Range Correlation
Here are some advised scope power settings and the distances where they could be effectively used. High power scopes will not be as efficient as lower powered scopes because too much zoom can be a bad thing. The same concept relates to longer ranges where the shooter needs sufficient power to see where to best aim the rifle.
Info on Glass Lens Coating
All modern rifle optic and scope lenses are covered. Lens finishing is an essential aspect of a rifle system when thinking about high end rifle optics and scope setups.
Info on Rifle Optic Lens Coatings – HD Versus ED
Some glass makers additionally use “HD” or high-definition glass coverings which take advantage of different procedures, components, polarizations, and chemical applications to draw out different color ranges and viewable target visibility through lenses. This high-definition coating is frequently used with more costly high density lens glass which decreases light’s chance to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious over things with well defined shapes as light hits the object from certain angles.
Single Finishing Versus Multi-Coating for Optics
Various optic lenses can even have various coatings applied to them. All lenses usually have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in many kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope company and the amount you spent paying for it. Both are signs of the lens quality.
Some scope producers 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.
Hydrophobic Coating for Rifle Scopes
Water on a lens doesn’t help with maintaining 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 hydrophilic or hydrophobic coating.
Glass Installing Options
Mounting solutions for scopes come in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use toss levers which allow rifle shooters to quickly install and remove the scopes.
Hex Key Glass Rings
Standard, clamp-on style mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use two separate rings to support the optic, and are normally made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This kind of scope mount is effective for rifle systems which need a resilient, unfailing mount which will not shift no matter how much the scope is moved or abuse the rifle takes. These are the design of mounts you really want to have for a dedicated scope setup on a reach out and touch someone hunting or tournament long gun which will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screws from backing out after they are mounted tightly in position. An example of these rings are the 30mm style made by the Vortex Optics company. The set normally costs around $200 USD
Glass Mounting Solutions with Quick-Release Cantilever Rings
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. Multiple scopes can also be switched out if they all use a complementary designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These kinds of mounts are useful and practical for rifles which are carried a lot, to take off the scope glass from the rifle for protection, or for sight systems which are employed between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
What to Know About Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can wreck a day on the range and your highly-priced optic by causing fogging and generating residue inside of the scope tube. A lot of optics prevent wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content prevention for basic use rifles, unless you plan on taking your rifle boating and are concerned about the scope still functioning if it goes over the side and you can still find the gun.
Gas Purged Rifle Optic Tubes
Another component of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the glass is less influenced by temp changes and pressure distinctions from the external environment which could potentially enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
