What You Need to Know About Glass
Rifle scopes allow you to precisely align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by using a series of lenses inside the scope. The scope’s alignment can be dialed in for consideration of many ecological elements like wind and elevation to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the target. Many contemporary rifle scopes and optics have about eleven parts which are found within and outside of the optic. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane a scope has determines where the reticle or crosshair is located in relation to the scopes zoom. It simply implies the reticle is behind or before the magnifying lens of the optic. Picking the most suitable form of rifle scope is dependent on what sort of hunting or shooting you intend on doing.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based on the level of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are small
- Experienced shooters who understand their target “hold over” as well as “lead” equations for their long guns
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. This induces the reticle to remain at the same dimensions relative to the amount of magnification being used. The result is that the reticle measurements evolve based on the zoom employed to shoot over greater ranges because the reticle markings represent different increments which vary with the magnification level. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular kinds of scopes are useful for:
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots happen within shorter ranges and proximities
- Shooters who would like a clearer optic sight picture without space taken up by the larger sized FFP reticle
About Rifle Glass Magnification
The amount 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.
Info on Fixed Power Lens Optics
A single power rifle scope and optic uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust given that it is a set power scope.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification levels. It will list the zoom amount in a configuration like 2-10×32. These numbers mean the magnification of the scope could be set between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power adjustment is achieved by applying the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some recommended scope power levels and the ranges where they can be efficiently used. Always remember that higher magnification glass will not be as efficient as lower magnification level optics and scopes since increased zoom can be a detractor. The exact same concept goes for longer distances where the shooter needs to have enough power to see exactly where to properly aim the rifle.
Details on Scope Lens Finishes
All contemporary rifle optic and scope lenses are coated. There are various types and qualities of lens finishes. When looking at luxury rifle optical systems, Lens finishing can be a very important element of defining the rifle’s capability. The lenses are one of the most essential components of the glass because they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses shields the lens surface as well as improves anti glare capabilities from excess daylight and color visibility.
HD Versus ED Lenses
Some scope brands also use “HD” or high-definition lens finishes which use various procedures, chemicals, elements, and polarizations to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses typically have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It must have a coating placed on it so that it will be optimally usable in many kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope developer and how much money you spent on it. Both the make and cost are signs of the lens quality.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Anti-water Lens Coating
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophobic or hydrophilic coating.
Glass Installation Choices
Mounting options for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use throw levers which permit rifle shooters to rapidly mount and remove the scopes.
Rifle Optic Mounts with Hex Key Rings
Standard, clamp-on style mounting scope rings use hex head screws to position to the flattop design Picatinny scope mount rails on the tops of rifles. These styles of scope mounts use a pair of individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This form of scope mount is effective for rifles which are in need of a resilient, hard use mount which will not shift regardless of just how much the scope is moved or abuse the rifle takes. These are the style of mounts you should get for a devoted scope setup on a long distance hunting or hard target interdiction firearm which will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to prevent the hex screw threads from backing out after they are installed tightly in position. An example of these rings are the 30mm type made by the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly attach and take off 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 mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while retaining the original sighting settings. These types of mounts come in practical for rifles which are hauled around a lot, to take off the glass from the rifle for protection, or for optics which are adopted between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day on the range and your expensive optic by triggering fogging and creating residue within the scope tube. The majority of optics protect against humidity from entering the scope tube with a series of sealing O-rings which are water resistant. Usually, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content avoidance for conventional use rifles, unless you anticipate taking your rifle on your motorboat and are concerned about the optic still working if it is submerged in water and you can still rescue the rifle.
Gas Purged Optic Tubes
Another part of avoiding the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the glass is less influenced by temperature changes and pressure variations from the external environment which could potentially allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
