Glass Information
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target over a distance. They do this through magnification by making use of a set of lenses inside the scope. The scope’s alignment can be adapted for consideration of various natural aspects like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based upon the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended target. Most contemporary rifle scopes and optics have about 11 parts which are found inside and externally on the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other elements. See all eleven parts of an optic.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has identifies where the reticle or crosshair is located in connection with the scopes magnification. It actually suggests the reticle is situated behind or before the magnifying lens of the scope. Picking the most suitable sort of rifle scope depends on what form of shooting or hunting you intend on undertaking.
First Focal Plane Optic Info
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who recognize their target “hold over” and also “lead” equations for their weapon
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle behind the magnifying lens. This induces the reticle to stay at the very same size relative to the volume of magnification being used. The end result is that the reticle dimensions shift based upon the magnification applied to shoot over greater ranges given that the reticle measurements present distinct increments which vary with the magnification. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These varieties of glass work for:
- Far away types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who want a clearer optic picture without area used up by the larger size FFP reticle
Magnification for Rifle Scopes
The quantity of magnification a scope supplies 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 comes with a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not fluctuate because it is fixed.
Adjustable Power Lens Glass
Variable power rifle scopes use enhanced power. The power change is performed by using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Glass
Here are some recommended scope powers and the ranges where they may be effectively used. High power rifle scope glass will not be as beneficial as lower magnification scopes considering too much magnification can be a negative aspect depending on your shooting distance. The same idea goes for longer ranges where the shooter needs adequate power to see where to properly aim the rifle.
About Glass Lens Coating
All modern rifle scope and optic lenses are layered. There are different types and qualities of lens coatings. When considering high end rifle targeting systems, Lens covering can be a vital aspect of defining the capability of the rifle. The glass lenses are one of the most essential pieces of the scope considering that they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses protects the lens surface as well as improves anti glare from excess sunrays and color discernibility.
ED Versus HD Rifle Scopes
Some scope producers also use “HD” or high-definition lens finishes which use different processes, aspects, polarizations, and chemicals to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Coating Versus Multi-Coating
Various optic lenses can even have various finishings applied to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully 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 light (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering 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 producer and how much you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope producers also make it a point to define if their optic lenses are layered or “multi” covered. This implies the lens has several treatments applied to them. If a lens gets multiple treatments, it can establish that a manufacturer is taking numerous actions to combat various environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This also doesn’t always imply the multi-coated lens will perform much better than a single layered lens. Being “much better” depends on the producer’s lens treatment solutions and the quality of components used in creating the rifle scope.
Anti-water Lens Coating
Water on a lens does not 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 fine example of this kind of treatment. It treats the surface of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Rifle Scope Installation Alternatives
Mounting solutions for scopes can be found in a few options. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically come in quick release versions which use manual levers which allow rifle shooters to rapidly mount and remove the glass.
Hex Key Rifle Glass Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long distance precision shooting. This type of scope install is wonderful for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. Several scopes can also be switched out if they all use a complementary style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping the original sighting settings. These types of mounts come in convenient for rifles which are moved around a lot, to take off the glass from the rifle for protection, or for aiming systems which are adopted in between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your expensive optic by causing fogging and producing residue inside of the scope tube. Most scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Details on Rifle Glass Tube Gas Purging
Another component of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the glass is less influenced by climate shifts and pressure distinctions from the external environment which may potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
