Glass Information
Rifle scopes permit you to specifically align a rifle at various targets by lining up your eye with the target over a distance. They do this through zoom using a set of lenses within the scope. The scope’s alignment can be adapted to take into account varied natural things like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle optics have about eleven parts which are located within and outside of the optic. These scope parts include the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle glass.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane a scope has determines where the reticle or crosshair lies relative to the optic’s magnifying adjustments. It simply indicates the reticle is located behind or before the magnifying lens of the optic. Picking out the most suitable type of rifle glass is based upon what form of hunting or shooting you plan on undertaking.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who know their aim point “hold over” and “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Scope Info
Second focal plane optics (SFP) feature the reticle to the rear of the magnifying lens. This triggers the reticle to stay at the same scale in connection with the amount of magnification being used. The result is that the reticle measurements shift based on the magnification chosen to shoot over lengthier distances considering that the reticle markings present different increments which vary with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular sorts of optics work for:
- Long distance kinds of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who select a clearer optic picture with less room taken up by the enlarged FFP reticle
Glass Zoom
The amount of zoom a scope provides is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Fixed Single Power Lens Rifle Optics
A single power rifle optic comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not fluctuate because it is a fixed power optic.
Adjustable Power Lens Rifle Scope Details
Variable power rifle scopes use enhanced power. The power modification is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some advised scope powers and the distances where they could be successfully used. Keep in mind that high power scopes will not be as efficient as lower powered glass because increased zoom can be a bad thing. The exact same idea goes for longer distances where the shooter needs to have adequate power to see precisely where to best aim the rifle.
Info on Rifle Glass Lens Coating
All modern rifle scope lenses are coated. There are various types and qualities of glass lens coatings. When looking at high end rifle scope setups, Lens finish can be a very important element of defining the rifle’s capability. The lenses are among the most essential pieces of the scope considering they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses shields the lens surface and even helps with anti glare from excess direct sunlight and color discernibility.
Details on Rifle Optic Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens coverings which use various techniques, aspects, chemicals, and polarizations to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Coating Versus Multi-Coating
Different optic lenses can also have different coatings applied to them. All lenses typically have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic assembly. This is since the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It needs to have a finishing put on it so that the lens will be efficiently usable in many types of environments, degrees of sunshine (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 producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are coated or “multi” covered. This indicates the lens has had multiple treatments applied to the surfaces. If a lens gets numerous treatments, it can indicate that a company is taking several steps to fight different environmental factors like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also doesn’t always suggest the multi-coated lens will perform better than a single covered lens. Being “much better” is dependent on the manufacturer’s lens treatment techniques and the quality of glass used in building the rifle scope.
Hydrophobic Rifle Glass Lens Finish
Water on an optic’s lens does not improve maintaining a clear sight picture through a scope at all. Many top of the line or premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the surface 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 move off of the scope to keep a clear, water free sight picture.
Choices for Mounting Scopes on Firearms
Installing options for scopes can be found in a couple of options. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically are made in quick release variations which use throw levers which allow rifle operators to quickly install and dismount the scope.
Hex Key Glass Rings
Basic, clamp style mounting optic rings use hex head screws to install to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use double detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are developed for far away precision shooting. This form of scope mount is excellent for rifle systems which are in need of a durable, hard use mount which will not move no matter how much the scope is moved about or jarring the rifle takes. These are the type of mounts you really want to have for a devoted scope setup on a reach out and touch someone hunting or interdiction long gun that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from backing out after they are mounted securely in place. An example of these rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Several scopes can also be swapped out if they all use a compatible style mount. These types of mounts are handy for rifles which are transported a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. The majority of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another element of avoiding the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the scope is less affected by temperature level changes and pressure differences from the external environment which might potentially 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 seek out.
