What You Need to Know About Rifle Glass
Rifle scopes allow you to exactly aim a rifle at various targets by aligning your eye with the target over a distance. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account different natural things like wind and elevation to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the target. A lot of modern-day rifle scopes and optics have around eleven parts which are found inside and outside of the scope. These parts consist of the rifle scope’s body, lenses, modification turrets, focus rings, and other parts. See all eleven parts of an optic.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the perfect type of rifle scope depends 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 zoom lens. This induces the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. For example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are minimal
- Experienced shooters who know their aim point “hold over” as well as “lead” equations for their firearms
- Shooters who don’t mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance types of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who like a clearer optic sight picture without area used up by the larger size FFP reticle
About Rifle Glass Zoom
The quantity of scope zoom you need on your scope depends upon the form of shooting you like to do. Just about every kind of rifle optic offers some level of zoom. The level of zoom a scope supplies is determined by the diameter, density, and curvatures of the lens glass within the rifle scope. The zoom of the optic is the “power” of the glass. This suggests what the shooter is aiming at through the scope is magnified times the power aspect of what can generally be seen by human eyes.
Fixed Power Lens Optic Facts
A single power rifle scope or optic comes with a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate because it is a fixed power scope.
Variable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power modification is handled by the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope powers and the distances where they could be efficiently used. Keep in mind that high power optics and scopes will not be as practical as lower magnification level optics due to the fact that increased magnification can be a negative thing in certain situations. The very same idea applies to extended ranges where the shooter needs enough power to see exactly where to best aim the rifle at the target.
Rifle Optic Lens Finishing
All modern rifle optic lenses are covered in special coatings. There are different types and qualities of glass coatings. When looking at luxury rifle optics and scope systems, Lens finish can be a very important component of defining the capability of the rifle. The lenses are one of the most crucial pieces of the scope 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 safeguards the lens surface area and also assists with anti glare from refracted natural light and color perception.
HD Versus ED Lenses
Some rifle scope producers additionally use “HD” or high-def lense finishings which apply various procedures, polarizations, components, and chemicals to draw out a wide range of color ranges and viewable definition through lenses. This high-definition finish is commonly used with increased density lens glass which brings down light’s capability to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be obvious over things with well defined shapes as light hits the object from specific angles.
Single Covering Versus Multi-Coating for Optics
Different scope lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic assembly. Because the lens isn’t just 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 it will be efficiently usable in numerous kinds 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 maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are covered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of products used in developing the rifle scope.
Anti-water Rifle Glass Lens Finish
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophilic or hydrophobic covering.
Choices for Installing Rifle Glass on Firearms
Installing options for scopes are available in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release versions which use manual levers which permit rifle operators to rapidly install and dismount the optics.
Hex Key Optic Ring Mounting Solutions
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 a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is fine for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
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 swapped out if they all use a complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely 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 back on the rifle while keeping precision. These types of mounts are useful and practical for rifles which are hauled around a lot, to take off the scope glass from the rifle for protection, or for scopes which are used between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your expensive optic by bringing about fogging and producing residue inside of the scope tube. The majority of scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another component of avoiding the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the scope is less impacted by temperature level shifts and pressure variations from the outside environment which could potentially allow 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.
