What You Need to Know About Glass
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target at range. They do this through zoom using a series of lenses inside the scope. The scope’s positioning can be adjusted to account for many natural factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the target. Many modern-day rifle optics have about 11 parts which are located internally and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other parts. Learn about the eleven parts of rifle optics.
About Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane an optic has identifies where the reticle or crosshair is located relative to the optic’s magnification. It actually implies the reticle is located behind or before the magnification lens of the optic. Selecting the best kind of rifle scope is based upon what form of shooting or hunting you intend on undertaking.
Info on First Focal Plane Scopes
First focal plane scopes (FFP) include the reticle ahead of the magnification lens. This causes the reticle to increase in size based upon the amount of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are minor
- Experienced shooters who understand their aim point “hold over” as well as “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
Second Focal Plane Scope Info
Second focal plane glass (SFP) come with the reticle to the rear of the magnifying lens. This induces the reticle to stay at the exact same scale in relation to the volume of magnification being used. The result is that the reticle measurements evolve based upon the zoom applied to shoot over lengthier ranges because the markings present different increments which can vary with the magnification. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These styles of glass work for:
- Long distance kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who desire a clearer optic picture with less room used up by the larger size FFP reticle
Optic Zoom
The amount of magnification a scope offers is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Optic Info
A single power rifle optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate because it is a set power scope.
Adjustable Power Lens Rifle Glass Details
Variable power rifle scopes use enhanced power. The power modification is performed by using the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power Level and Range Correlation
Here are some recommended scope powers and the distances where they may be successfully used. High power optics will not be as beneficial as lower powered glass since too much magnification can be a negative aspect depending on your shooting distance. The very same idea applies to extended ranges where the shooter needs sufficient power to see precisely where to properly aim the rifle.
Info on Lens Covering
All modern-day rifle scope lenses are covered in special coatings. There are different types and qualities of glass coatings. Lens covering is an important element of a rifle when contemplating high end rifle optics and targeting units. The lenses are among the most essential parts of the optic because they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses shields the lens exterior and even helps with anti glare capabilities from refracted direct sunlight and color presence.
HD Versus ED Optic Lens Coatings
Some rifle scope suppliers will also use “HD” or high-definition lense coverings that apply various procedures, chemicals, components, and polarizations to enhance separate colors and viewable definition through lenses. This high-def finish is often used with increased density lens glass which lowers light’s capability to refract by means of the lens glass. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be noticeable over objects with hard edges and outlines as light hits the object from certain angles.
Rifle Optic Lens Single Covering Versus Multi-Coating
Different optic lenses can also have different coatings used to them. All lenses usually have at least some type of treatment or finishing used to them before being used in a rifle scope or optic.
Single covered 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 reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope maker and how much money you spent on it. The scope’s maker and cost are signs of the lens quality.
Some scope producers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Rifle Glass Lens Hydrophobic Finishing
Water on a lens doesn’t support retaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic 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 deals with the exterior of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to preserve a clear, water free sight picture.
Alternatives for Installing Rifle Scopes on Firearms
Installing solutions for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release variations which use manual levers which allow rifle operators to rapidly install and remove the optics.
Hex Key Rifle Optic Rings
Standard, clamp design 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long range precision shooting. This type of scope install is excellent for rifles which require a resilient, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Several scopes can also be swapped out if they all use a compatible design mount. These types of mounts are convenient for long guns which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between multiple rifles or are situationally focused.
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day on the range and your expensive optic by triggering fogging and producing residue within the scope tube. Most scopes prevent moisture from getting in the optical tube with a series of sealing O-rings which are water resistant. Normally, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness avoidance for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are worried about the optic still functioning if it is submerged in water and you can still recover the firearm.
Gas Purged Optic Tubes
Another component of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the glass is less impacted by condition alterations and pressure distinctions from the outdoor environment which may potentially permit water vapor to leak 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.
