What You Need to Know About Glass
Rifle scopes enable you to specifically align a rifle at various targets by lining up your eye with the target over a range. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s positioning can be adapted to account for varied ecological factors like wind and elevation increases 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 viewing through the optic as you align the scope’s crosshair or reticle with the target. Most modern rifle optics have around 11 parts which are found inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, elevation turrets, objective focus rings, and other parts. Learn about the eleven parts of scopes.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has identifies where the reticle or crosshair is located in connection with the optic’s magnification. It simply indicates the reticle is situated behind or in front of the magnifying lens of the scope. Deciding upon the most effective kind of rifle scope is based on what variety of shooting or hunting you anticipate doing.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This induces 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 range. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are low
- Experienced shooters who know their aim point “hold over” and also “lead” relationships for their long guns
- Shooters who do not mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. This induces the reticle to remain at the exact same size in connection with the volume of zoom being used. The end result is that the reticle dimensions adapt based upon the zoom employed to shoot over longer distances considering the reticle markings present various increments which change with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These styles of glass are handy for:
- Far away forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who select a clearer optic picture with less space used up by the larger size FFP reticle
Rifle Optic Zoom
The quantity of magnification a scope supplies 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.
Fixed Power Lens Rifle Optic Info
A single power rifle scope uses 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 magnification of this type of optic can not adjust since it is set from the factory.
Variable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification power levels. These types of scopes will note the zoom level in a format such as 2-10×32. These numbers imply the magnification of the scope can be adjusted in between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power adjustment is accomplished by operating the power ring part of the scope near the back of the scope by the eye bell.
Optic Power and Range Correlation
Here are some advised scope power levels and the distances where they may be successfully used. Bear in mind that high power optics will not be as efficient as lower magnification level scopes since too much magnification can be a bad thing. The same goes for longer distances where the shooter needs enough power to see exactly where to properly aim the rifle.
Lens Coating for Rifle Optics
All contemporary rifle optic and scope lenses are layered. There are different types and qualities of glass finishes. Lens finish can be an essential aspect of a rifle when looking into high end rifle optics and scope systems. The glass lenses are one of the most crucial components of the glass considering that they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses shields the lens surface as well as assists with anti glare capabilities from excess light and color visibility.
Details on Lens Coatings – HD Versus ED
Some optic suppliers also use “HD” or high-def lens coatings that employ various processes, components, polarizations, and chemicals to enhance various colors and viewable target definition through the lens. This HD covering is normally used with increased density glass which decreases light’s ability to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often noticeable around objects with hard shapes as light hits the object from various angles.
Info on Single Finishing Versus Multi-Coating
Various scope lenses can even have different coverings applied to them. All lenses generally have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It needs to have a covering applied to it so that the lens will be optimally functional in lots of kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope producers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Details on Anti-water Finishing
Water on a lens does not support retaining a clear sight picture through an optic at all. Lots of top of the line or high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior of the Steiner optic lens so the water particles can not bind to it or develop surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Options for Installing Glass on Long Guns
Installing options for scopes are available in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually can be found in quick release variations which use throw levers which permit rifle shooters to quickly mount and dismount the optics.
Hex Key Glass Ring Mounting Solutions
Basic, clamp style mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are created for far away precision shooting. This type of scope mount is excellent for rifles which need a resilient, hard use mount which will not move no matter how much the scope is moved or jarring the rifle takes. These are the style of mounts you really want to have for a dedicated optics system on a long distance scouting or sniper competition firearm that will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to stop the hex screw threads from wiggling out after they are installed tightly in place. An example of these rings are the 30mm style from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Glass Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, several scopes can often be switched out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining the original sighting settings. These types of mounts come in convenient for shooting platforms which are shipped a lot, to remove the optic from the rifle for protection, or for aiming systems which are adopted in between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Scope Tubes
Another element of avoiding the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the glass is less affected by condition alterations and pressure distinctions from the outdoor environment which could possibly permit water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
