Rifle Glass Info
Rifle scopes permit you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by utilizing a series of lenses within the scope. The scope’s positioning can be adjusted to account for various environmental considerations like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle optics have around 11 parts which are arranged inside and outside of the scope. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. See all eleven parts of an optic.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the finest type of rifle optic depends on what type of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards by using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are low
- Experienced shooters who recognize their aim point “hold over” and “lead” relationships for their long guns
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots take place within much shorter ranges and distances
- Shooters who would like a clearer optic picture without space taken up by the larger size FFP reticle
Ins and Outs of Optic Magnification
The amount of zoom a scope offers is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Glass Details
A single power rifle optic and scope comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust given that it is a fixed power optic.
Variable Power Lens Glass Facts
Variable power rifle scopes have adjustable power. It will note the zoom level in a configuration like 2-10×32. These numbers suggest the zoom of the scope could be adjusted in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power manipulation is accomplished using the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power and Range Correlation of Scopes
Here are some advised scope power levels and the distances where they can be efficiently used. High power rifle scope glass will not be as effective as lower magnification glass considering that too much magnification can be a bad thing. The same idea goes for extended distances where the shooter needs enough power to see precisely where to properly aim the rifle.
Lens Coating for Glass
All modern rifle optic lenses are coated. There are various types and qualities of lens coatings. When considering high end rifle targeting units, Lens finishing can be a significant element of defining the capability of the rifle. The glass lenses are among the most crucial parts of the optic since they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses safeguards the lens surface area and even assists with anti glare from excess sunlight and color profiles.
HD Versus ED Lenses
Some glass makers additionally use “HD” or high-definition lens finishings which employ various procedures, polarizations, chemicals, and aspects to enhance various color ranges and viewable definition through the lens. This high-def finishing is normally used with more costly high density lens glass which reduces light’s chance to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious around objects with hard outlines as light hits the item from certain angles.
Scope Lens Single Coating Versus Multi-Coating
Different scope lenses can even have different finishings applied to them. All lenses typically have at least some type of treatment or covering applied to them prior to 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 is part of the carefully tuned optic. It needs to have a coating placed on it so that it will be optimally usable in numerous kinds of environments, degrees of light (full VS shade), 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 layered 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 coated or “multi” coated. This suggests the lens has several treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can prove that a company is taking several actions to combat different natural aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This additionally does not always indicate the multi-coated lens will perform better than a single coated lens. Being “better” depends on the maker’s lens treatment innovation and the quality of glass used in creating the rifle optic.
Optic Lens Hydrophobic Coating
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic anti-water coating.
Scope Installation Choices
Installing solutions for scopes are available 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 normally come in quick release variations which use manual levers which allow rifle shooters to rapidly install and remove the scopes.
Hex Key Rifle Scope Rings
Standard, clamp-on style mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use two detached rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This form of scope mount is effective for rifles which need a long lasting, hard use mount which will not change no matter how much the scope is moved about or jarring the rifle takes. These are the style of mounts you really want to have for a devoted scope setup on a long distance scouting or tournament long gun that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screws from backing out after they are mounted tightly in place. An example of these rings are the 30mm style from the Vortex Optics company. The set normally costs around $200 USD
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Multiple scopes can also be swapped out if they all use a similar style mount. These types of mounts are convenient for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles or are situationally focused.
Info on Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your highly-priced optic by triggering fogging and making residue within the scope tube. Most optics protect against humidity from entering the optical tube with a series of sealing O-rings which are waterproof. Usually, these water-resistant scopes can be submerged under 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 conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are concerned about the optic still working if it goes over the side and you can still salvage the firearm.
Glass Gas Purging
Another part of preventing the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the glass is less affected by temperature alterations and pressure distinctions from the outside environment which might possibly permit water vapor to leak 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.
