All About Rifle Glass
Rifle scopes permit you to specifically aim a rifle at different targets by lining up your eye with the target at range. They do this through magnification by making use of a set of lenses inside the scope. The scope’s positioning can be adjusted to account for many ecological considerations like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely 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. Many modern-day rifle scopes and optics have around eleven parts which are located within and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, windage dials, focus rings, and other components. See all eleven parts of optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the finest type of rifle optic is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. For example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who have an idea for their target “hold over” and also “lead” equations for their firearms
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
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 measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who select a clearer optic picture without area taken up by the bigger FFP reticle
The quantity of zoom a scope offers is figured out 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.
About Fixed Single Power Lens Rifle Optics
A single power rifle optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust considering that it is a set power scope.
Info About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom amount in a format such as 2-10×32. These numbers indicate the zoom of the scope could be changed between 2x and 10x power. This also involves the powers in-between 2 and 10. The power modification is achieved by applying the power ring component of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power settings and the ranges where they may be effectively used. Always remember that high magnification optics and scopes will not be as practical as lower magnification level optics because increased magnification can be a negative thing in certain situations. The same idea applies to extended ranges where the shooter needs to have enough power to see where to properly aim the rifle.
Scope Lens Covering
All present day rifle optic lenses are layered. Lens coating is a vital aspect of a rifle’s setup when buying high end rifle optics and scope setups.
HD Versus ED Lenses
Some optic suppliers also use “HD” or high-def lens coatings which make the most of different processes, polarizations, rare earth compounds, and components to draw out separate color ranges and viewable target visibility through lenses. This high-definition covering is commonly used with increased density glass which drops light’s chance to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible around objects with well defined shapes as light hits the object from particular angles.
Rifle Scope Lens Single Finish Versus Multi-Coating
Different optic lenses can likewise have various finishes applied 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 decreasing 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 company and the amount you spent paying for it. Both are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are coated or “multi” covered. This suggests the lens has had several treatments applied to them. If a lens gets several treatments, it can prove that a manufacturer is taking multiple actions to fight various environmental factors like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also does not necessarily suggest the multi-coated lens is better than a single coated lens. Being “better” depends on the producer’s lens treatment innovation and the quality of components used in building the rifle optic.
Anti-water Lens Finish
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 military grade scope companies will coat their lenses with a hydrophobic or hydrophilic finishing.
Scope Installation Choices
Mounting approaches for scopes are available in a few options. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use manual levers which enable rifle shooters to quickly install and remove the glass.
Rifle Optic Mounting Solutions with Hex Key Rings
Standard, clamp type mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on rifles. These styles of scope mounts use two individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for far away accuracy shooting. This form of scope mount is excellent for rifles which need to have a resilient, unfailing mount which will not shift regardless of just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you really want to have for a specialized optics setup on a reach out and touch someone hunting or sniper competition firearm which will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on screws to stop the hex screws from backing out after they are installed tightly in position. An example of these rings are the 30mm style made by the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts are convenient for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles or are situationally focused.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. The majority of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Optic Tubes
Another element of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the glass is less impacted by condition alterations and pressure differences from the external environment which could possibly permit water vapor to leak 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.
