What You Need to Know About Rifle Glass
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target at range. They do this through magnifying the target by utilizing a series of lenses within the scope. The scope’s positioning can be adapted to take into account various ecological things like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the target. Many modern rifle scopes have around eleven parts which are located inside and outside of the scope. These optic pieces consist of the rifle scope’s body, lenses, elevation dials, objective focus rings, and other elements. See all eleven parts of an optic.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the perfect type of rifle optic is based around what type of shooting you plan to do.
Info on First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the amount of zoom being used. The result is that the reticle measurements are the same at the magnified range 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 corresponding tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are small
- Experienced shooters who understand their aim point “hold over” and also “lead” ratios for their rifles
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the zoom 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 kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within shorter ranges and proximities
- Shooters who desire a clearer optic picture with less space used up by the larger sized FFP reticle
Magnification for Glass
The amount of zoom a scope offers is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info About Fixed Power Lens Rifle Scopes
A single power rifle optic and scope comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a fixed power scope.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes can be modified between magnified levels. The power modification is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power Level and Ranges
Here are some advised scope power levels and the distances where they can be successfully used. Consider that high power optics will not be as efficient as lower magnification level scopes since too much magnification can be a bad thing. The very same idea goes for longer distances where the shooter needs enough power to see exactly where to best aim the rifle.
About Lens Coverings
All modern-day rifle optic lenses are covered in special coatings. There are various types and qualities of glass lens finishes. Lens finish can be a crucial aspect of a rifle when thinking of luxury rifle optics and scope systems. The glass lenses are among the most vital components of the scope because they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses shields the lens surface and also helps with anti glare capabilities from excess light and color exposure.
Details on Scope Lens Coatings – HD Versus ED
Some rifle glass producers also use “HD” or high-def lens finishes which use different processes, polarizations, rare earth compounds, and aspects to draw out different color ranges and viewable target definition through the lens. This high-definition covering is frequently used with increased density lens glass which lowers light’s chance to refract by means of the lens glass. Some scope manufacturers use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often noticeable over items with defined shapes as light hits the object from particular angles.
Single Rifle Optic Lens Covering Versus Multi-Coating
Different optic lenses can likewise have various finishings used to them. All lenses typically have at least some type of treatment or finish used to them before they are used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you spent on it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.
About Anti-water Covering
Water on an optic’s lens doesn’t assist with keeping a clear sight picture through an optic in any way. Numerous top of the line and premium optic makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the surface of the Steiner glass lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Optic Installation Alternatives
Mounting options for scopes are available in a few choices. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically are made in quick release variations which use throw levers which enable rifle operators to rapidly mount and dismount the scope.
Hex Key Optic Ring Mounts
Basic, clamp style mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on rifles. These forms of scope mounts use double individual rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are created for long distance precision shooting. This kind of scope mount is great for rifles which require a resilient, rock solid mount which will not move despite 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 dedicated optics setup on a long distance hunting or competitors firearm that will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to keep the hex screw threads from wiggling out after they are installed tightly in position. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set generally costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly remove 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 in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping accuracy. These types of mounts are useful and convenient for rifles which are hauled around a lot, to take off the optic from the rifle for protection, or for scopes which are utilized in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Info on Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day on the range and your costly optic by triggering fogging and making residue within the scope’s tube. Most scopes protect against wetness from going into the scope tube with a series of sealing O-rings which are waterproof. Normally, these water-resistant optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough humidity prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the scope still functioning if it falls overboard and you can still find the gun.
Gas Purged Scope Tubes
Another part of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the optic is less affected by condition shifts and pressure distinctions from the external environment which may possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
