What You Need to Know About Rifle Glass
Rifle scopes allow you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnification by utilizing a set of lenses inside the scope. The scope’s alignment can be adjusted to account for many environmental elements 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 viewing using the optic as you align the scope’s crosshair or reticle with the intended target. Most modern rifle scopes and optics have around 11 parts which are arranged internally and externally on the scope. These parts consist of the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other parts. See all eleven parts of a rifle optical system.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the perfect type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Scope Info
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who understand their target “hold over” plus “lead” ratios for their rifles
- Shooters who don’t mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. 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 reticle measurement.
- Long distance types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots take place within much shorter ranges and distances
- Shooters who want a clearer optic sight picture without room used up by the bigger FFP reticle
Zoom for Rifle Glass
The quantity of magnification a scope offers is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Scopes
A single power rifle optic and scope will have a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust because it is a fixed power scope.
Adjustable Power Lens Rifle Glass Details
Variable power rifle scopes can be modified between magnified levels. The power adjustment is handled by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope power settings and the distances where they could be efficiently used. Bear in mind that high magnification glass will not be as effective as lower magnification level scopes because excessive zoom can be a detractor. The very same idea goes for extended ranges where the shooter needs enough power to see where to best aim the rifle at the target.
About Lens Covering
All contemporary rifle optic and scope lenses are covered in special coatings. There are various types and qualities of coatings. Lens finish can be an important aspect of a rifle when contemplating high end rifle optics and scope systems. The lenses are one of the most significant pieces of the glass considering that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses offers protection to the lens surface area and improves anti glare from excess direct sunlight and color discernibility.
HD Versus ED Lenses
Some rifle scope makers additionally use “HD” or high-def glass finishings that apply various procedures, aspects, rare earth compounds, and polarizations to extract various colors and viewable target definition through lenses. This high-definition finish is often used with increased density glass which brings down light’s opportunity to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration may be noticeable around objects with defined shapes as light hits the item from specific angles.
Single Covering Versus Multi-Coating
Different scope lenses can even have different finishings 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. Due to the fact that 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 finishing put on it so that it will be optimally functional in lots of kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing 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 makers likewise make it a point to specify if their optic lenses are layered or “multi” covered. This indicates the lens has numerous treatments applied to them. If a lens receives numerous treatments, it can prove that a maker is taking numerous actions to fight various environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This additionally does not necessarily imply the multi-coated lens is much better than a single covered lens. Being “better” depends upon the maker’s lens treatment technology and the quality of materials used in developing the rifle optic.
Info on Hydrophobic Covering
Water on a lens doesn’t assist with maintaining a clear sight picture through an optic in any way. Many top of the line and premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Glass Installation Options
Mounting approaches for scopes are available in a couple of choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically are made in quick release variations which use throw levers which permit rifle shooters to rapidly install and dismount the scopes.
Hex Key Glass Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These kinds of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This type of scope mount is very good for rifle systems which are in need of a resilient, hard use mount which will not change despite just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should have for a dedicated optics setup on a reach out and touch someone scouting or hard target interdiction firearm that will rarely need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to stop the hex screw threads from wiggling out after they are mounted safely in place. An example of these rings are the 30mm type made by the Vortex Optics company. The set usually costs around $200 USD
Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible 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 protecting the scope, or for optics which are used between numerous rifles.
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can ruin a day of shooting and your highly-priced optic by inducing fogging and developing residue within the scope’s tube. A lot of optics prevent wetness from getting in the optical tube with a system of sealing O-rings which are water resistant. Generally, these optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content prevention for standard use rifles, unless you plan on taking your rifle on a boat and are concerned about the scope still performing if it goes overboard and you can still recover the firearm.
Optic Gas Purging
Another part of avoiding the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the optic is less altered by condition shifts and pressure differences from the external environment which could 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.
