Facts About Glass
Rifle scopes allow you to precisely aim a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through zoom by utilizing a set of lenses inside the scope. The scope’s positioning can be dialed in for consideration of different ecological things like wind speed and elevation to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle optics have about 11 parts which are found within and outside of the scope body. These parts include the rifle scope’s body, lenses, elevation turrets, focus rings, and other parts. See all eleven parts of scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the perfect type of rifle glass is based on what type of shooting you plan to do.
Info About First Focal Plane Optics
First focal plane optics (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the level of zoom being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who understand their aim point “hold over” and “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who would like a clearer optic sight picture without room taken up by the bigger FFP reticle
Details on Rifle Optic Zoom
The amount of zoom a scope provides is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Glass Details
A single power rifle scope uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a fixed power scope.
Adjustable Power Lens Rifle Optic Info
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom degree in a format like 2-10×32. These numbers indicate the zoom of the scope can be changed between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power manipulation is achieved utilizing the power ring part of the scope near the rear of the scope by the eye bell piece.
Rifle Glass Power Level and Ranges
Here are some suggested scope powers and the ranges where they can be successfully used. Remember that high power scopes and optics will not be as efficient as lower powered scope and optics since increased magnification can be a negative thing in certain situations. The same idea relates to extended ranges where the shooter needs enough power to see where to best aim the rifle at the target.
Lens Covering for Rifle Scopes
All modern rifle scope lenses are covered in special coatings. There are various types and qualities of glass finishes. When shopping for luxury rifle targeting setups, Lens coating can be a crucial element of defining the capability of the rifle. The glass lenses are one of the most essential components of the glass given that they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses safeguards the lens exterior and assists with anti glare from refracted sunshine and color presence.
Info on Lens Coatings – HD Versus ED
Some rifle scope companies also use “HD” or high-definition lens coverings which use various procedures, chemicals, components, and polarizations to extract a wide range of colors and viewable definition through lenses. This HD finish is normally used with higher density glass which decreases light’s potential to refract through the lens glass. Some scope makers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often visible over items with hard outlines as light hits the object from certain angles.
What to Know About Single Finish Versus Multi-Coating
Various optic lenses can also have various coverings used to them. All lenses typically have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically 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 layered lens depends on the scope manufacturer and how much you spent on it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Anti-water Glass Lens Coating
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic covering.
Scope Installing Options
Installing options for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also normally can be found in quick release versions which use throw levers which enable rifle shooters to rapidly install and remove the optics.
Optic Mounts with Hex Key Rings
Standard, clamp-on design mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use a pair of separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for long distance accuracy shooting. This kind of scope mount is ideal for rifle systems which are in need of a durable, hard use mount which will not shift regardless of just how much the scope is moved or jarring the rifle takes. These are the design of mounts you should get for a faithful scope setup on a long distance hunting or competitors firearm that will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to keep the hex screw threads from backing out after they are installed safely in place. An example of these mounting rings are the 30mm type from Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining precision. These kinds of mounts come in beneficial for shooting platforms which are carried a lot, to remove the scope glass from the rifle for protection, or for scopes which are chosen for use in between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle glass can destroy a day of shooting and your highly-priced optic by triggering fogging and making residue within the scope tube. The majority of scopes prevent wetness from going into the optical tube with a system of sealing O-rings which are waterproof. Usually, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for standard use rifles, unless you anticipate taking your rifle sailing and are worried about the scope still functioning if it falls overboard and you can still salvage the gun.
Glass Gas Purging
Another element of avoiding the accumulation of moisture within the rifle optic’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 altered by temperature level alterations and pressure distinctions from the outdoor environment which may possibly enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
