Rifle Glass Facts
Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnification by utilizing a set of lenses inside the scope. The scope’s alignment can be adapted for consideration of separate natural elements like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle optics have around 11 parts which are located internally and on the exterior of the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the finest type of rifle optic is based on what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the amount of zoom being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non amplified range. For instance, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the corresponding tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are very little
- Experienced shooters who understand their aim point “hold over” and also “lead” equations for their long gun
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle behind 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.
- Far away styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within much shorter ranges and spaces
- Shooters who want a clearer optic sight picture with less space taken up by the larger sized FFP reticle
Magnification for Rifle Glass
The quantity of zoom a scope provides is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info on Fixed Single Power Lens Optics
A single power rifle scope and optic comes with a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not fluctuate because it is a fixed power optic.
About Adjustable Power Lens Glass
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 mean the magnification of the scope can be set in between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power shift is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Scope Power and Range Correlation
Here are some suggested scope power levels and the distances where they may be successfully used. Always remember that high magnification scopes will not be as effective as lower powered optics due to the fact that increased magnification can be a negative thing in certain situations. The same goes for longer ranges where the shooter needs to have sufficient power to see where to properly aim the rifle at the target.
Rifle Optic Lens Finishing
All contemporary rifle optic lenses are layered. There are different types and qualities of glass finishings. Lens finishing can be an essential element of a rifle’s setup when looking into high end rifle optics and targeting systems. The lenses are among the most important pieces of the glass considering they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses shields the lens surface as well as helps with anti glare from refracted natural light and color profiles.
HD Versus ED Lens Coatings
Some glass manufacturers additionally use “HD” or high-def lense finishes that apply different procedures, chemicals, elements, and polarizations to draw out various color ranges and viewable definition through the lens. This HD coating is often used with higher density glass which drops light’s capability to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around objects with defined shapes as light hits the item from particular angles.
Single Rifle Glass Lens Covering Versus Multi-Coating
Different scope lenses can also have various coverings applied to them. All lenses usually have at least some kind of treatment or finishing applied to them before being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing 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 manufacturer and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Anti-water Rifle Scope Lens Finish
Water on a lens doesn’t help with preserving a clear sight picture through an optic whatsoever. Lots of top of the line and premium optic makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the exterior of the Steiner glass lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Scopes on Firearms
Mounting options for scopes can be found in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use manual levers which allow rifle operators to quickly mount and remove the optics.
Hex Key Scope Ring Mounts
Standard, clamp type mounting scope rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two individual rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are created for far away accuracy shooting. This type of scope mount is great for rifle systems which are in need of a resilient, unfailing mount which will not change despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you want for a devoted optics setup on a far away hunting or tournament long gun which will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used to protect against the hex screws from backing out after they are mounted securely in position. An example of these rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a similar style mount. These types of mounts come in handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used between multiple rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and creating residue inside of the scope tube. Most scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Scope Tubes
Another part of avoiding the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the optic is less affected by condition shifts and pressure distinctions from the external environment which might potentially permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
