All About Rifle Glass
Rifle scopes allow you to exactly align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by employing a set of lenses inside the scope. The scope’s alignment can be adapted to account for separate ecological considerations like wind speed 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 seeing via the scope as you align the scope’s crosshair or reticle with the target. Many modern rifle scopes have around 11 parts which are found inside and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other parts. See all eleven parts of scopes.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the optimal type of rifle scope depends on what type of shooting you plan on doing.
First Focal Plane Scopes
First focal plane glass (FFP) come with the reticle ahead of the magnifying lens. This induces the reticle to increase in size based on the level of magnification being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. For example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who recognize their target “hold over” plus “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. This triggers the reticle to remain at the exact same overall size in connection with the amount of magnification being used. The outcome is that the reticle measurements adjust based on the magnification used to shoot over lengthier ranges considering that the reticle measurements represent different increments which change with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These kinds of glass work for:
- Far away kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who want a clearer optic sight picture with less space taken up by the larger sized FFP reticle
Ins and Outs of Rifle Scope Zoom
The extent of scope magnification you need on your scope is based on the type of shooting you wish to do. Just about every kind of rifle glass supplies some level of magnification. The level of zoom a scope offers is determined by the dimension, density, and curves of the lens glass inside of the rifle scope. The magnification of the scope is the “power” of the opic. This implies what the shooter is looking at through the scope is magnified times the power aspect of what can usually be seen by human eyes.
Fixed Single Power Lens Scopes
A single power rifle 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 since it is set from the factory.
Variable Power Lens Rifle Scope Facts
Variable power rifle scopes can be adjusted between magnification levels. It will note the magnification amount in a format like 2-10×32. These numbers suggest the zoom of the scope could be set in between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power modification is accomplished by operating the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Glass
Here are some suggested scope power levels and the ranges where they may be successfully used. Always remember that high power optics and scopes will not be as practical as lower powered scopes since excessive magnification can be a bad thing. The same idea applies to longer distances where the shooter needs adequate power to see exactly where to properly aim the rifle.
Info on Lens Coating
All modern rifle optic lenses are coated. There are different types and qualities of glass finishes. When researching high end rifle optics and scope devices, Lens finish can be a vital aspect of a rifle. The lenses are among the most essential parts of the optic due to the fact that they are what your eye looks through while sighting a rifle in on the point of impact. The finishing on the lenses protects the lens surface and helps with anti glare from excess light and color discernibility.
Info on Rifle Scope Lens Coatings – HD Versus ED
Some rifle scope manufacturers even use “HD” or high-definition glass coatings that use various procedures, polarizations, rare earth compounds, and aspects to enhance a wide range of color ranges and viewable definition through lenses. This HD finish is frequently used with greater density glass which decreases light’s capability to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration can be visible around things with well defined shapes as light hits the object from various angles.
Single Coating Versus Multi-Coating for Rifle Glass
Various optic lenses can even have various coverings applied to them. All lenses normally have at least some kind of treatment or finish applied to them before being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a covering placed on it so that it will be efficiently usable in numerous types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in building the rifle scope.
Optic Lens Hydrophobic Finishing
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic anti-water coating.
Optic Installing Alternatives
Installing options for scopes can be found in a few choices. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally can be found in quick release variations which use throw levers which enable rifle operators to quickly mount and dismount the scope.
Hex Key Glass Rings
Basic, clamp-on design mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use a pair of separate rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are created for far away precision shooting. This kind of scope mount is exceptional for rifles which are in need of a long lasting, unfailing mount which will not change regardless of how much the scope is moved about or jarring the rifle takes. These are the design of mounts you want for a faithful scope setup on a long distance scouting or interdiction long gun which will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to stop the hex screw threads from backing out after they are mounted firmly in place. An example of these rings are the 30mm style made by the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, several scopes can often be swapped on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining precision. These kinds of mounts are useful and convenient for rifles which are shipped a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are chosen for use in between numerous rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Moisture 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. Many scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Scope Tubes
Another component of avoiding the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the glass is less affected by temperature level shifts and pressure distinctions from the outside environment which could possibly allow 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.
