All About Rifle Glass
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They do this through zoom using a series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of separate natural elements like wind speed and elevation to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes and optics have around 11 parts which are arranged internally and outside of the scope. These scope parts consist of the rifle scope’s body, lenses, windage dials, focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has establishes where the reticle or crosshair is located in relation to the scopes magnification. It simply suggests the reticle is behind or before the magnification lens of the scope. Considering the most desired kind of rifle scope is dependent on what style of hunting or shooting you plan on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This induces the reticle to increase in size based upon the amount 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. For instance, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at one hundred yards using 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who recognize their target “hold over” and also “lead” relationships for their long guns
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (SFP) feature the reticle behind the magnification lens. This induces the reticle to remain at the very same size in connection with the level of magnification being used. The outcome is that the reticle dimensions shift based upon the magnification applied to shoot over longer ranges considering that the reticle measurements represent distinct increments which fluctuate with the zoom level. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These sorts of optics are useful for:
- Long distance styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who desire a clearer optic sight picture with less area used up by the bigger FFP reticle
The amount of zoom a scope provides is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Glass Info
A single power rifle scope or optic comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not adjust given that it is a set power scope.
Adjustable Power Lens Optics
Variable power rifle scopes use enhanced power. The power change is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Optic Power Level and Range Correlation
Here are some advised scope power levels and the ranges where they can be effectively used. Highly magnified scopes will not be as beneficial as lower magnification level rifle scope glass considering that too much zoom can be a negative aspect depending on your shooting distance. The same idea goes for longer ranges where the shooter needs to have adequate power to see where to properly aim the rifle.
Lens Finishing for Scopes
All modern rifle scope and optic lenses are coated. Lens finish is a vital aspect of a shooting platform when looking into high end rifle optics and scope setups.
Info on Glass Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens coatings which use different techniques, polarizations, chemicals, and aspects to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Rifle Glass Lens Single Finishing Versus Multi-Coating
Different optic lenses can also have various coatings applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope designer and just how much you spent paying for it. Both the manufacturer and amount are indications of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This implies the lens has had multiple treatments applied to the surfaces. If a lens receives numerous treatments, it can prove that a producer is taking multiple steps to fight different natural aspects like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This also does not necessarily imply the multi-coated lens will perform better than a single layered lens. Being “better” hinges on the maker’s lens treatment techniques and the quality of products used in constructing the rifle glass.
Hydrophobic Finishing for Rifle Optics
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Rifle Scope Installing Options
Installing approaches for scopes are available in a few options. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use manual levers which permit rifle operators to quickly mount and dismount the scopes.
Hex Key Glass Rings
Standard, clamp style mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use two detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are manufactured for far away accuracy shooting. This form of scope mount is effective for rifles which need a long lasting, unfailing mount which will not move regardless of how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a faithful scope system on a far away hunting or interdiction rifle which will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount screws to stop the hex screws from wiggling out after they are installed safely in position. An example of these mounting rings are the 30mm style made by Vortex Optics. 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. Numerous scopes can even be swapped out if they all use a similar design mount. These types of mounts are handy for long guns which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle glass can ruin a day on the range and your pricey optic by causing fogging and creating residue within the scope tube. Many optics prevent moisture from entering the scope tube with a series of sealing O-rings which are waterproof. Generally, these water resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture avoidance for basic use rifles, unless you intend on taking your rifle aboard a watercraft and are worried about the scope still working if it goes over the side and you can still retrieve the rifle.
Rifle Glass Gas Purging
Another element of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the scope is less impacted by temp changes and pressure variations from the outside environment which may possibly permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
