What You Need to Know About Glass
Rifle scopes allow you to precisely align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by using a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of many ecological things like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle scopes have around eleven parts which are arranged within and outside of the optic. These scope parts include the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other components. Learn about the eleven parts of glass.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has decides where the reticle or crosshair is located relative to the scopes magnification. It literally means the reticle is situated behind or in front of the magnification lens of the scope. Looking for the most desired form of rifle scope is based on what form of shooting you intend on doing.
Info on First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are helpful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who know their target “hold over” and “lead” relationships for their long gun
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. This triggers the reticle to stay at the same scale relative to the amount of magnification being used. The final result is that the reticle dimensions evolve based upon the magnification applied to shoot over lengthier distances considering that the reticle measurements represent distinct increments which fluctuate with the zoom. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular sorts of scopes are convenient for:
- Long distance types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within much shorter distances and ranges
- Shooters who want a clearer optic sight picture without area taken up by the bigger FFP reticle
Glass Magnification
The amount of scope magnification you need on your glass depends on the form of shooting you plan to do. Practically every style of rifle optic gives some amount of magnification. The amount of zoom a scope provides is determined by the size, thickness, and curvatures of the lens glass within the rifle optic. The magnification level of the optic is the “power” of the opic. This means what the shooter is aiming at through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Info on Fixed Power Lens Scopes
A single power rifle optic comes with a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust because it is a fixed power scope.
Variable Power Lens Glass
Variable power rifle scopes can be modified between magnified settings. The power change is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power levels and the distances where they may be successfully used. Remember that high magnification glass will not be as effective as lower powered glass because excessive magnification can be a negative thing in certain situations. The same idea relates to longer distances where the shooter needs to have sufficient power to see precisely where to best aim the rifle.
About Lens Covering
All modern rifle scope and optic lenses are covered in special coatings. There are different types and qualities of glass lens coverings. When researching luxury rifle optical setups, Lens covering can be a significant aspect of defining the capability of the rifle. The glass lenses are among the most key components of the optic considering that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses protects the lens surface and also assists with anti glare capabilities from refracted natural light and color discernibility.
About Rifle Glass Lens Coatings – HD Versus ED
Some optic companies also use “HD” or high-def lense finishings which take advantage of different processes, components, polarizations, and chemicals to draw out different colors and viewable target visibility through lenses. This high-definition finishing is commonly used with more costly, high density glass which brings down light’s opportunity to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration may be noticeable around things with hard outlines as light hits the object from certain angles.
Single Finishing Versus Multi-Coating
Various optic lenses can also have different finishes applied to them. All lenses generally have at least some kind of treatment or covering applied to them before being used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a coating applied to it so that it will be efficiently usable in numerous types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope developer and just how much you spent on it. Both the manufacturer and amount are signs of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” covered. This implies the lens has had numerous treatments applied to them. If a lens receives multiple treatments, it can indicate that a maker is taking multiple steps to fight various natural factors like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This also does not always mean the multi-coated lens will perform better than a single covered lens. Being “much better” depends upon the maker’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Anti-water Coating for Glass
Water on an optical lens doesn’t assist with preserving a clear sight picture through a scope in any way. Lots of 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 fine example of this kind 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 result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Rifle Optic Installing Options
Installing solutions for scopes come in a couple of options. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also normally come in quick release variations which use manual levers which enable rifle operators to quickly mount and dismount the scope.
Hex Key Optic Ring Mounting Solutions
Basic, clamp-on style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use two individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are made for long distance accuracy shooting. This type of scope mount is excellent for rifle systems which need a long lasting, unfailing mount which will not shift despite just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you want for a devoted scope system on a far away hunting or competition long gun which will pretty much never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to keep the hex screws from backing out after they are installed tightly in position. An example of these mounting rings are the 30mm type from the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Numerous scopes can also be switched out if they all use a compatible style mount. These types of mounts are handy for long guns which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used in between several rifles.
Info Around Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can destroy a day on the range and your costly optic by inducing fogging and generating residue within the scope tube. Many optics protect against moisture from entering the optical tube with a series of sealing O-rings which are water resistant. Usually, these water resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough humidity prevention for basic use rifles, unless you intend on taking your rifle aboard watercrafts and are concerned about the scope still functioning if it is submerged in water and you can still recover the gun.
Gas Purged Rifle Optic Tubes
Another element of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the optic is less affected by temp alterations and pressure differences from the external environment which could potentially permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
