Information About Glass
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification by employing a set of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of numerous environmental things like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes and optics have about 11 parts which are found inside and externally on the scope. These parts consist of the rifle scope’s body, lenses, windage turrets, focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane a scope has establishes where the reticle or crosshair lies in relation to the scopes magnification. It simply indicates the reticle is behind or in front of the magnification lens of the scope. Looking for the most ideal kind of rifle optic is based on what style of shooting you intend on doing.
First Focal Plane Optic Info
First focal plane glass (FFP) feature the reticle before the zoom lens. This causes the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. For example, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at 100 yards using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are very little
- Experienced shooters who know their aim point “hold over” plus “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
Second Focal Plane Glass
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 measurement would be 1/5th of the non “zoom” tick.
- Long distance kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots occur within shorter spaces and ranges
- Shooters who select a clearer optic picture without space taken up by the bigger FFP reticle
Zoom for Glass
The amount of magnification a scope supplies is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Glass Facts
A single power rifle scope and optic uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is a set power scope.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is handled by the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Rifle Scopes
Here are some advised scope power settings and the ranges where they could be efficiently used. Highly magnified rifle scope glass will not be as useful as lower magnification level scopes because too much magnification can be a bad thing. The same idea goes for longer ranges where the shooter needs adequate power to see where to properly aim the rifle.
Optic Lens Covering
All top teir rifle scope and optic lenses are layered. Lens finishing is a significant aspect of a shooting system when buying high end rifle optics and scope equipment.
HD Versus ED Rifle Optic Lens Coatings
Some scope makers also use “HD” or high-definition lens coatings which use different methods, polarizations, components, and chemicals to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Scope Lens Single Covering Versus Multi-Coating
Various optic lenses can even have different finishes applied to them. All lenses generally have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a finish put on it so that it will be optimally usable in many types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Scope Lens Hydrophobic Covering
Water on a lens doesn’t assist with preserving 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 anti-water finishing.
Options for Installing Optics on Firearms
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 types of mounts also usually come in quick release variations which use manual levers which allow rifle shooters to rapidly mount and dismount the optics.
Hex Key Glass Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation 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 are developed for long range precision shooting. This type of scope install is perfect for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Numerous scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for long guns which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used between multiple rifles.
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. The majority of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Details on Rifle Optic Tube Gas Purging
Another element of preventing the accumulation of wetness inside of the rifle optic’s 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 alterations and pressure variations from the outdoor environment which may possibly enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
