What You Need to Know About Glass
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target over a distance. They do this through magnifying the target using a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account many natural elements like wind speed and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the target. The majority of modern-day rifle optics have about eleven parts which are arranged internally and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane an optic has decides where the reticle or crosshair lies in regard to the optic’s zoom. It literally indicates the reticle is behind or before the magnifying lens of the optic. Deciding on the most desired sort of rifle optic depends on what form of shooting you intend on undertaking.
About First Focal Plane Scopes
First focal plane optics (FFP) include the reticle before the magnifying lens. This triggers the reticle to increase in size based on the extent of magnification being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. For example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who know their aim point “hold over” as well as “lead” equations for their firearms
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Optic Info
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom 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 measurement.
- Long distance kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots happen within shorter proximities and ranges
- Shooters who like a clearer optic picture without area taken up by the enlarged FFP reticle
Scope Zoom
The quantity of zoom a scope supplies is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Optics
A single power rifle optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not adjust because it is a set power scope.
Info on Adjustable Power Lens Optics
Variable power rifle scopes use enhanced power. The power modification is handled using the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power Level and Ranges
Here are some recommended scope power levels and the ranges where they may be efficiently used. Always remember that high magnification optics and scopes will not be as practical as lower magnification level scopes due to the fact that too much magnification can be a bad thing. The same idea relates to extended ranges where the shooter needs to have adequate power to see where to properly aim the rifle.
Lens Finish for Rifle Optics
All modern-day rifle scope lenses are layered. There are various types and qualities of lens finishings. Lens finish is an essential element of a rifle when looking into high-end rifle optics and scope units. The lenses are among the most critical components of the glass since 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 even helps with anti glare from refracted sunrays and color discernibility.
About Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens finishings which use different procedures, polarizations, chemicals, and aspects to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Optics
Different scope lenses can also have various finishes 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 assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It needs to have a finish applied to it so that the lens will be efficiently functional in many types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope maker and just how much you spent for it. Both are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. This implies the lens has multiple treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can show that a company is taking multiple steps to combat different environmental elements like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also does not always imply the multi-coated lens will perform better than a single layered lens. Being “much better” is dependent on the maker’s lens treatment solutions and the quality of products used in developing the rifle optic.
Scope Lens Anti-water Finish
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Glass Installation Choices
Mounting approaches for scopes are available in a few choices. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use toss levers which enable rifle shooters to quickly install and remove the optics.
Hex Key Rifle Optic Rings
Standard, clamp design mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use a pair of individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This type of scope mount is very good for rifles which are in need of a long lasting, rock solid mount which will not move regardless of just how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a faithful optics setup on a reach out and touch someone hunting or hard target interdiction rifle that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to keep the hex screw threads from backing out after they are installed safely in place. An example of these rings are the 30mm style from Vortex Optics. The set usually costs around $200 USD
Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. A wide range of scopes can also be switched out if they all use a complementary designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping accuracy. These types of mounts come in beneficial for rifles which are moved a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are employed between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day on the range and your expensive optic by triggering fogging and developing residue inside of the scope’s tube. The majority of scopes protect against humidity from entering the optical tube with a system of sealing O-rings which are water resistant. Typically, these scopes can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity avoidance for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle on boats and are worried about the optic still performing if it goes over the side and you can still retrieve the rifle.
Gas Purged Optic Tubes
Another part of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the optic is less altered by climate alterations and pressure distinctions from the outside environment which could potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
