Rifle Glass Info
Rifle scopes permit you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification by employing a series of lenses within the scope. The scope’s alignment can be dialed in for the consideration of separate ecological things like wind and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes and optics have around 11 parts which are found within and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, windage dials, focus rings, and other elements. See all eleven parts of optics.
About Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has decides where the reticle or crosshair is located in relation to the optic’s magnification. It literally indicates the reticle is behind or in front of the magnification lens of the optic. Deciding on the most reliable kind of rifle scope is dependent on what sort of shooting you plan on undertaking.
About First Focal Plane Glass
First focal plane optics (FFP) include the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the extent of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. For instance, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minor
- Experienced shooters who know their aim point “hold over” as well as “lead” relationships for their long gun
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Far away types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and distances
- Shooters who would like a clearer optic sight picture with less space used up by the larger size FFP reticle
Glass Magnification
The quantity of zoom a scope supplies is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Optic Facts
A single power rifle optic and scope uses a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust since it is a fixed power scope.
Variable Power Lens Optics
Variable power rifle scopes can be changed between magnification increments. It will note the magnification degree in a format such as 2-10×32. These numbers imply the zoom of the scope could be set in between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power shift is achieved utilizing the power ring component of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power settings and the ranges where they may be efficiently used. High power glass will not be as effective as lower powered optics considering too much magnification can be a bad thing. The very same idea relates to longer ranges where the shooter needs increased power to see precisely where to properly aim the rifle.
Glass Lens Finish
All modern rifle optic lenses are layered. There are different types and qualities of glass coverings. Lens covering can be an important element of a rifle when looking into luxury rifle optics and targeting systems. The glass lenses are among the most essential components of the glass considering that 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 exterior and also improves anti glare capabilities from refracted sunrays and color visibility.
Details on Rifle Glass Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens finishes which use various techniques, polarizations, components, 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.
Rifle Optic Lens Single Finishing Versus Multi-Coating
Various optic lenses can also have different coverings used to them. All lenses normally have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing 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 upon the scope designer and how much money you paid for it. Both the make and cost are indicators of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Coverings
Water on an optical lens doesn’t assist with keeping a clear sight picture through a scope at all. Numerous top of the line or high-end scope producers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the surface area of the Steiner scope lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Choices for Mounting Rifle Scopes on Long Guns
Mounting solutions for scopes come in a couple of options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also normally come in quick release variations which use toss levers which allow rifle operators to rapidly mount and remove the scopes.
Hex Key Optic Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is fine for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a complementary style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while retaining precision. These types of mounts come in handy for shooting platforms which are transferred between vehicles a lot, to remove the scope from the rifle for protection, or for scopes which are used between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can spoil a day of shooting and your costly optic by inducing fogging and producing residue within the scope’s tube. Most optics prevent moisture from going into the scope tube with a series of sealing O-rings which are waterproof. Typically, these water resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are concerned about the scope still performing if it goes over the side and you can still find the gun.
Scope Gas Purging
Another part of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the scope is less affected by temperature level changes and pressure differences from the external environment which could potentially enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
