What You Need to Know About Glass
Rifle scopes permit you to precisely align a rifle at various targets by aligning your eye with the target over a distance. They do this through magnification by using a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of many ecological factors like wind and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based on the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle optics have about eleven parts which are found internally and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other components. Learn about the eleven parts of scopes.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Going for the best type of rifle glass is based on what type of shooting you plan to do.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where calculations are marginal
- Experienced shooters who have an idea for their target “hold over” as well as “lead” correlations for their long gun
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight space 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 induces the reticle to stay at the very same dimensions relative to the volume of zoom being used. The effect is that the reticle dimensions shift based upon the zoom used to shoot over longer ranges considering that the markings represent distinct increments which vary with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These particular styles of optics are convenient for:
- Long distance forms of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots take place within shorter ranges and spaces
- Shooters who prefer a clearer optic picture without room used up by the bigger FFP reticle
Optic Magnification
The amount of magnification a scope provides is identified 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.
About Fixed Single Power Lens Rifle Glass
A single power rifle scope and optic uses a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate because it is set from the factory.
Adjustable Power Lens Scope Facts
Variable power rifle scopes have adjustable power. It will list the zoom amount in a format like 2-10×32. These numbers mean the zoom of the scope could be set in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power adjustment is accomplished using the power ring component of the scope near the back of the scope by the eye bell.
Scope Power Level and Range Correlation
Here are some advised scope powers and the distances where they can be successfully used. High power optics will not be as efficient as lower powered rifle scope glass since too much zoom can be a negative aspect depending on your shooting distance. The exact same concept relates to extended distances where the shooter needs to have increased power to see where to best aim the rifle at the target.
Lens Covering for Optics
All contemporary rifle glass lenses are layered. Lens finishing can be a vital aspect of a shooting platform when looking at high end rifle optics and scope systems.
Info on Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens finishings which use different processes, polarizations, elements, and chemicals to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Rifle Optic Lens Coating Versus Multi-Coating
Various optic lenses can even have various finishes applied to them. All lenses generally have at least some type of treatment or finish 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 requires a coating to be applied to it so that it will be efficiently functional in lots of types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in constructing the rifle scope.
Anti-water Optic Lens Coating
Water on an optical lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and premium optic makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the surface area of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Rifle Glass Mounting Options
Installing solutions for scopes can be found in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and dismount the scopes.
Rifle Scope Mounts with Hex Key Rings
Standard, clamp-on style mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use double individual rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are designed for far away precision shooting. This kind of scope mount is excellent for rifles which require a long lasting, unfailing mount which will not shift regardless of how much the scope is moved or abuse the rifle takes. These are the design of mounts you should have for a specialized optics system on a far away hunting or hard target interdiction long gun which will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to stop the hex screws from backing out after they are installed firmly in position. An example of these rings are the 30mm type from the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, several scopes can often be swapped in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving the original sighting settings. These types of mounts come in practical for rifles which are moved around a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are utilized between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day on the range and your pricey optic by triggering fogging and producing residue inside of the scope’s tube. Many optics prevent moisture from entering the optical tube with a system of sealing O-rings which are waterproof. Usually, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough wetness avoidance for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are worried about the scope still functioning if it falls overboard and you can still recover the gun.
Info on Rifle Glass Tube Gas Purging
Another part of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the optic is less affected by temp alterations and pressure variations from the external environment which could potentially enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
