Glass Info
Rifle scopes allow you to exactly aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by using a series of lenses inside the scope. The scope’s positioning can be adapted for consideration of various environmental considerations like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the target. A lot of contemporary rifle optics have about 11 parts which are arranged internally and externally on the scope body. These optic pieces include the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other components. See all eleven parts of a scope.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the best type of rifle glass depends on what type of shooting you plan to do.
About First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at 100 yards by using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who have an idea for their target “hold over” and “lead” equations for their weapon
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane glass (SFP) feature the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the very same dimensions in connection with the level of zoom being used. The final result is that the reticle dimensions evolve based upon the zoom used to shoot over longer ranges because the markings present different increments which change with the magnification level. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular styles of optics are useful for:
- Long distance forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots take place within much shorter ranges and proximities
- Shooters who like a clearer optic sight picture without space taken up by the bigger FFP reticle
Magnification for Scopes
The quantity of scope magnification you need on your optic is based on the type of shooting you wish to do. Almost every style of rifle optic offers some level of magnification. The amount of zoom a scope gives is established by the dimension, thickness, and curves of the lenses within the rifle scope. The magnification of the optic is the “power” of the scope. This signifies what the shooter is observing through the scope is amplified times the power factor of what can generally be seen by human eyes.
About Single Power Lens Rifle Scopes
A single power rifle optic uses a zoom 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 optic can not fluctuate since it is set from the factory.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. It will note the magnification level in a format such as 2-10×32. These numbers mean the magnification of the scope could be changed in between 2x and 10x power. This also includes the powers in-between 2 and 10. The power adjustment is accomplished by employing the power ring part of the scope near the rear of the scope by the eye bell piece.
Glass Power and Range Correlation
Here are some recommended scope power levels and the distances where they could be successfully used. High power rifle scope glass will not be as efficient as lower powered scopes since too much magnification can be a negative aspect depending on your shooting distance. The very same idea applies to extended distances where the shooter needs adequate power to see exactly where to best aim the rifle at the target.
Info on Lens Coating
All modern rifle optic lenses are coated. There are different types and qualities of glass coverings. Lens finishing is a crucial aspect of a rifle’s setup when looking at high end rifle optics and scope systems. The lenses are among the most essential components of the optic given that they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses safeguards the lens exterior as well as improves anti glare from excess light and color visibility.
HD Versus ED Lenses
Some optic makers also use “HD” or high-def lens coatings which make the most of various procedures, polarizations, elements, and chemicals to draw out numerous colors and viewable target visibility through lenses. This HD covering is normally used with increased density glass which brings down light’s opportunity to refract by means of the lens glass. Some scope manufacturers 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 or deviance which is similarly called color distortion or fringing. Chromatic aberration is often obvious over things with hard edges and shapes as light hits the object from certain angles.
Rifle Glass Lens Single Finishing Versus Multi-Coating
Various optic lenses can likewise have various coverings applied to them. All lenses generally have at least some type of treatment or coating used to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Anti-water Lens Coverings
Water on an optic’s lens doesn’t improve retaining a clear sight picture through an optic in any way. Lots of top of the line or premium optic makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the surface of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Options for Mounting Rifle Optics on Firearms
Installing solutions for scopes come in a few options. 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 typically can be found in quick release variations which use toss levers which enable rifle operators to quickly mount and dismount the glass.
Hex Key Rifle Scope Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 are created for long distance precision shooting. This type of scope install is wonderful for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. If they all use a comparable design mount, multiple scopes can often be switched in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping precision. These types of mounts are useful and practical for rifles which are shipped a lot, to take off the scope from the rifle for protection, or for optics which are utilized between numerous rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Details on Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. Many scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another component of avoiding the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the optic is less impacted by temp changes and pressure distinctions from the external environment which could 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.
