Rifle Glass Details
Rifle scopes allow you to exactly align a rifle at different targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by using a set of lenses inside the scope. The scope’s positioning can be dialed in to take into account various environmental factors like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based upon the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle optics have about eleven parts which are located inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. See all eleven parts of optics.
About Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane a scope has identifies where the reticle or crosshair is located in regard to the optic’s zoom. It simply suggests the reticle is located behind or in front of the magnification lens of the optic. Selecting the best form of rifle glass depends on what type of shooting you intend on undertaking.
First Focal Plane Scopes
First focal plane glass (FFP) include the reticle in front of the zoom lens. This induces the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are small
- Experienced shooters who know their aim point “hold over” as well as “lead” equations for their firearms
- Shooters who don’t mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Second Focal Plane Optic Details
Second focal plane glass (SFP) come with the reticle to the rear of the zoom lens. This causes the reticle to remain at the exact same dimensions relative to the amount of zoom being used. The end result is that the reticle measurements change based on the zoom employed to shoot over longer ranges because the reticle measurements present distinct increments which can vary with the magnification. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These sorts of scopes work for:
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots take place within much shorter ranges and distances
- Shooters who would like a clearer optic sight picture without area taken up by the larger sized FFP reticle
Rifle Scope Magnification
The amount of zoom a scope provides is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Optics
A single power rifle scope will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not adjust considering that it is a fixed power scope.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification power levels. It will note the magnification degree in a format like 2-10×32. These numbers mean the zoom of the scope can be adjusted between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power adjustment is achieved by working with the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power and Ranges
Here are some recommended scope power settings and the ranges where they can be successfully used. High power rifle scope glass will not be as useful as lower magnification level glass considering too much zoom can be a bad thing. The exact same concept applies to longer distances where the shooter needs increased power to see exactly where to properly aim the rifle at the target.
Glass Lens Finish
All contemporary rifle optic lenses are coated. There are different types and qualities of glass lens finishes. Lens finish is a crucial element of a rifle when contemplating high end rifle optics and targeting systems. The lenses are one of the most critical parts of the scope since they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses shields the lens exterior as well as improves anti glare capabilities from refracted sunshine and color profiles.
Details on Lens Coatings – HD Versus ED
Some rifle scope makers also use “HD” or high-def lens coverings which apply different processes, aspects, polarizations, and chemical applications to draw out a wide range of color ranges and viewable definition through the lens. This high-def finishing is often used with increased density lens glass which lowers light’s ability to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious around items with defined shapes as light hits the object from specific angles.
Single Coating Versus Multi-Coating
Various scope lenses can even have various coverings applied to them. All lenses typically have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in lots of kinds of environments, degrees of sunshine (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 shield the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope manufacturer and how much you spent on it. Both the make and cost are signs of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Anti-water Scope Lens Finishing
Water on a scope’s lens doesn’t help with maintaining a clear sight picture through a scope in any way. Lots of top of the line or premium optic producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior surfaces of the Steiner glass lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Rifle Scope Installation Choices
Installing solutions for scopes can be found in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release variations which use throw levers which permit rifle operators to quickly install and remove the glass.
Hex Key Optic Ring Mounting Solutions
Normal, clamp style 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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope mount is fine for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abused.
Rifle Glass Mounts 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. If they all use a comparable design mount, a number of scopes can also be switched on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while retaining the original sighting settings. These types of mounts come in convenient for shooting platforms which are carried a lot, to remove the optic from the rifle for protection, or for aiming systems which are adopted in between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can mess up a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. A lot of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Info on Rifle Glass Tube Gas Purging
Another component of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less influenced by climate shifts and pressure variations from the external environment which may possibly permit 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 seek out.
