Rifle Glass Information
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by utilizing a set of lenses inside the scope. The scope’s alignment can be dialed in to account for many environmental factors like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes have about eleven parts which are found within and on the exterior of the scope. These parts include the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other components. See all eleven parts of optics.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the finest type of rifle optic depends on what type of shooting you plan to do.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who have an idea for their target “hold over” and “lead” equations for their firearms
- Shooters who don’t 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) include the reticle behind the magnification 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 reticle measurement.
- Long distance kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within shorter distances and ranges
- Shooters who prefer a clearer optic picture with less room used up by the larger size FFP reticle
Zoom for Scopes
The amount of magnification a scope provides 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 Power Lens Glass
A single power rifle optic will have a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate given that it is a fixed power scope.
Adjustable Power Lens Scopes
Variable power rifle scopes can be modified between magnified settings. The power adjustment is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope power settings and the distances where they can be successfully used. Always remember that high power scopes and optics will not be as effective as lower powered glass since increased zoom can be a detractor. The same applies to longer distances where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Scope Lens Coating
All modern rifle optic and scope lenses are layered. There are various types and qualities of glass lens finishings. Lens finish can be an important element of a rifle when looking at high-end rifle optics and targeting systems. The glass lenses are one of the most critical parts of the optic due to the fact that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses offers protection to the lens surface area as well as improves anti glare capabilities from excess natural light and color presence.
HD Versus ED Rifle Glass Lens Coatings
Some scope makers also use “HD” or high-definition lens finishes which use different procedures, chemicals, components, and polarizations to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can even have various finishes applied to them. All lenses generally have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a covering applied to it so that the lens will be efficiently functional in many kinds of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering 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 on the scope manufacturer and how much you paid for it.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of materials used in building the rifle scope.
Anti-water Lens Finishing
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Options for Mounting Rifle Optics on Firearms
Installing approaches for scopes come in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally come in quick release variations which use manual levers which allow rifle shooters to rapidly install and dismount the glass.
Hex Key Optic Ring Mounting Solutions
Standard, 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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long distance accuracy shooting. This type of scope install is wonderful for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a compatible style mount. These types of mounts are convenient for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles or are situationally focused.
What to Know About Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle glass can destroy a day on the range and your pricey optic by causing fogging and generating residue inside of the scope tube. Many optics protect against humidity from going into the scope tube with a series of sealing O-rings which are waterproof. Normally, these water-resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture content avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle on boats and are worried about the scope still functioning if it goes over the side and you can still retrieve the gun.
About Optic Tube Gas Purging
Another part of preventing the accumulation of moisture within 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 affected by temp alterations and pressure differences from the external environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
