Information About Glass
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through magnification by employing a set of lenses within the scope. The scope’s alignment can be adjusted for the consideration of many natural factors like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes and optics have around 11 parts which are located internally and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other parts. See all eleven parts of scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the perfect type of rifle glass depends on what type of shooting you plan on doing.
First Focal Plane Glass Facts
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are very little
- Experienced shooters who have an idea for their target “hold over” plus “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who choose a clearer optic picture with less room used up by the larger sized FFP reticle
Magnification for Optics
The quantity of scope zoom you need on your optic depends upon the kind of shooting you intend to do. Practically every kind of rifle glass delivers some amount of magnification. The level of magnification a scope gives is established by the dimension, thickness, and curvatures of the lens glass within the rifle scope. The zoom of the optic is the “power” of the scope. This suggests what the shooter is observing through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Fixed Single Power Lens Rifle Glass Facts
A single power rifle optic will have 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 zoom of this type of scope can not adjust because it is set from the factory.
Adjustable Power Lens Optics
Variable power rifle scopes use enhanced power. The power adjustment is performed by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Scopes
Here are some advised scope powers and the ranges where they can be effectively used. High power rifle scope glass will not be as efficient as lower magnification level glass since too much magnification can be a negative aspect depending on your shooting distance. The same idea goes for longer distances where the shooter needs to have enough power to see exactly where to best aim the rifle at the target.
Info on Scope Lens Finish
All current rifle optic and scope lenses are coated. Lens finishing can be a significant element of a shooting platform when looking at high end rifle optics and scope setups.
Info on Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens coatings which use various procedures, chemicals, polarizations, and aspects to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Coating Versus Multi-Coating for Optics
Various optic lenses can even have different coatings applied to them. All lenses typically have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic. This is since the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in numerous kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope maker and the amount you spent for it. Both the manufacturer and amount are indicators 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 maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Finish
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Lots of top of the line and premium scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or create surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Rifle Glass Installation Options
Mounting solutions for scopes come in a few choices. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release versions which use manual levers which allow rifle operators to quickly mount and remove the scopes.
Hex Key Glass Ring Mounts
Standard, clamp type mounting scope rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use a pair of individual rings to support the optic, and are made from 7075 T6 billet aluminum which are manufactured for far away precision shooting. This type of scope mount is good for rifles which require a resilient, hard use mount which will not shift no matter just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you want for a dedicated scope system on a far away hunting or tournament firearm that will seldom need to be altered or adjusted. 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 installed securely in place. An example of these rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Several scopes can even be swapped out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between numerous rifles or are situationally focused.
Info Around Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day of shooting and your pricey optic by triggering fogging and developing residue within the scope tube. Many scopes prevent moisture from entering the optical tube with a series of sealing O-rings which are water resistant. Typically, these scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample humidity avoidance for conventional use rifles, unless you plan on taking your rifle boating and are concerned about the scope still performing if it goes overboard and you can still find the rifle.
Optic Gas Purging
Another component of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the glass is less altered by temperature level changes and pressure distinctions from the outside environment which may possibly enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
