About Rifle Glass
Rifle scopes permit you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They do this through zoom by using a set of lenses within the scope. The scope’s alignment can be adapted for the consideration of separate environmental factors like wind and elevation to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle optics have around 11 parts which are found inside and on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, elevation turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of rifle scopes.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane an optic has determines where the reticle or crosshair lies in connection with the scopes magnifying adjustments. It literally suggests the reticle is located behind or in front of the magnification lens of the scope. Choosing the most effective form of rifle glass is dependent on what kind of hunting or shooting you plan on doing.
First Focal Plane Optic Facts
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who understand their target “hold over” as well as “lead” ratios for their firearm
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. This triggers the reticle to remain at the very same scale in relation to the amount of zoom being used. The final result is that the reticle dimensions adjust based upon the magnification applied to shoot over longer distances because the markings present distinct increments which fluctuate with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These particular sorts of glass work for:
- Long distance kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and proximities
- Shooters who choose a clearer optic sight picture without space taken up by the enlarged FFP reticle
Details on Rifle Glass Magnification
The extent of scope zoom you need on your glass depends upon the type of shooting you plan to do. Virtually every type of rifle optic offers some level of zoom. The amount of zoom a scope delivers is determined by the diameter, thickness, and curves of the lenses within the rifle optic. The magnification level of the scope is the “power” of the scope. This signifies what the shooter is looking at through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Fixed Power Lens Optic Info
A single power rifle optic comes with a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust since it is a fixed power optic.
About Adjustable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power adjustment is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Scopes
Here are some recommended scope powers and the distances where they could be effectively used. Highly magnified optics will not be as efficient as lower magnification glass given that too much magnification can be a bad thing. The very same idea applies to extended distances where the shooter needs to have increased power to see precisely where to best aim the rifle at the target.
Glass Lens Finish
All contemporary rifle scope and optic lenses are covered in special coatings. There are different types and qualities of lens coverings. Lens finish can be an essential element of a rifle’s setup when looking at luxury rifle optics and scope equipment. The glass lenses are among the most essential components of the optic because they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses offers protection to the lens surface area and improves anti glare from refracted sunshine and color discernibility.
HD Versus ED Lens Coatings
Some scope producers likewise use “HD” or high-definition lens coverings which use different methods, chemicals, elements, and polarizations to draw out different colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Glass Lens Covering Versus Multi-Coating
Various optic lenses can also have various coverings applied to them. All lenses generally have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic. Because the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally functional in lots of types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope designer and how much you spent paying for it. The scope’s maker and cost are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. This implies the lens has multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can indicate that a maker is taking several actions to fight various environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also doesn’t necessarily mean the multi-coated lens will perform better than a single covered lens. Being “much better” depends upon the manufacturer’s lens treatment technology and the quality of materials used in building the rifle glass.
Anti-water Lens Coverings
Water on an optic’s lens doesn’t support retaining a clear sight picture through a scope at all. Lots of top of the line or high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the surface area of the Steiner scope lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Glass Installation Alternatives
Installing solutions for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally come in quick release versions which use manual levers which permit rifle shooters to quickly mount and remove the scopes.
Hex Key Rifle Scope Ring Mounts
Standard, clamp type mounting optic rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use double detached rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are made for long distance accuracy shooting. This kind of scope mount is great for rifles which require a resilient, rock solid mount which will not shift no matter how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a devoted scope system on a reach out and touch someone hunting or tournament firearm which will rarely need to be changed 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 installed safely in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly 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 handy for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used in between multiple rifles.
Details on Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can wreck a day on the range and your pricey optic by resulting in fogging and producing residue inside of the scope tube. A lot of optics protect against wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Normally, these water resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture prevention for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle on a boat and are concerned about the scope still working if it is submerged in water and you can still find the firearm.
About Optic Tube Gas Purging
Another element of preventing the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the optic is less impacted by temperature alterations and pressure differences from the external environment which could possibly allow water vapor to leak 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.
