What You Need to Know About Glass
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by employing a set of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of different ecological factors like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes have about eleven parts which are found internally and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other components. See all eleven parts of a rifle optical system.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the perfect type of rifle scope is based on what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where computations are minimal
- Experienced shooters who recognize their target “hold over” plus “lead” equations for their firearms
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
Info 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 reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who choose a clearer optic picture with less area used up by the larger size FFP reticle
Zoom for Rifle Optics
The extent of scope magnification you require depends on the kind of shooting you like to do. Almost every style of rifle scope supplies some degree of zoom. The amount of magnification a scope delivers is identified by the dimension, density, and curves of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the scope. This indicates what the shooter is observing through the scope is magnified times the power factor of what can normally be seen by human eyes.
Fixed Single Power Lens Rifle Glass Details
A single power rifle optic will have a zoom 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 kind of optic can not fluctuate considering that it is a fixed power optic.
Info About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be tweaked between magnified settings. The power modification is handled using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Optics
Here are some suggested scope power levels and the distances where they could be efficiently used. High power glass will not be as beneficial as lower powered scopes due to the fact that too much magnification can be a negative aspect depending on your shooting distance. The same applies to longer distances where the shooter needs to have sufficient power to see precisely where to properly aim the rifle.
Details on Lens Finishing
All modern-day rifle scope lenses are coated. There are different types and qualities of lens coatings. When considering high end rifle optics and scope setups, Lens finish can be a critical component of defining the rifle’s capability. The glass lenses are among the most critical pieces of the optic as they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses shields the lens surface and even helps with anti glare capabilities from refracted sunshine and color recognition.
Details on Scope Lens Coatings – HD Versus ED
Some rifle scope manufacturers even use “HD” or high-def lense finishings which apply various procedures, components, chemicals, and polarizations to enhance separate colors and viewable target definition through lenses. This HD covering is typically used with increased density glass which decreases light’s ability to refract through the lens glass. Some scope brands use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable over things with well defined outlines as light hits the object from specific angles.
Info on Single Covering Versus Multi-Coating
Various optic lenses can even have various finishings applied to them. All lenses typically have at least some type of treatment or finish applied to them before being used in a rifle scope or optic. Due to the fact that 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 efficiently functional in many types of environments, degrees of light (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” coated. This means the lens has multiple treatments applied to the surfaces of the glass. If a lens gets several treatments, it can indicate that a manufacturer is taking several steps to fight various natural factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also doesn’t necessarily imply the multi-coated lens will perform much better than a single covered lens. Being “much better” is dependent on the maker’s lens treatment techniques and the quality of materials used in developing the rifle optic.
Hydrophobic Lens Coverings
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic anti-water coating.
Choices for Installing Rifle Optics on Long Guns
Mounting options for scopes can be found in a few choices. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically are made in quick release variations which use manual levers which permit rifle shooters to quickly mount and dismount the optics.
Hex Key Glass Rings
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 two different rings to support the optic, and are made from 7075 T6 billet aluminum which is designed for long range precision shooting. This type of scope mount is perfect for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Numerous scopes can also be switched out if they all use a similar style mount. These types of mounts come in handy for rifles which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles or are situationally focused.
About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can spoil a day on the range and your highly-priced optic by triggering fogging and generating residue within the scope tube. Most optics protect against humidity from getting in the optical tube with a system of sealing O-rings which are waterproof. Usually, these optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture prevention for basic use rifles, unless you anticipate taking your rifle sailing and are worried about the optic still performing if it goes overboard and you can still retrieve the gun.
About Glass Tube Gas Purging
Another part of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the optic is less influenced by condition alterations and pressure variations from the outside 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 good rifle scope to look for.
