Information About Glass
Rifle scopes enable you to specifically aim a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through zoom by utilizing a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of various natural factors like wind and elevation to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes and optics have about 11 parts which are located internally and externally on the scope. These parts consist of the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other parts. Learn about the eleven parts of rifle scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the perfect type of rifle optic is based on what type of shooting you plan on doing.
About First Focal Plane Scopes
First focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the extent of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified distance. 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 kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who recognize their target “hold over” as well as “lead” equations for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and spaces
- Shooters who want a clearer optic picture with less space taken up by the enlarged FFP reticle
Rifle Optic Zoom
The quantity of magnification a scope provides is determined by the size, density, 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 Scopes
A single power rifle optic or scope comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a set power scope.
Adjustable Power Lens Glass
Variable power rifle scopes can be modified between magnified levels. The power modification is performed by the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power Level and Range Correlation
Here are some suggested scope power settings and the ranges where they can be effectively used. High power rifle scope glass will not be as beneficial as lower magnification level scopes considering too much zoom can be a bad thing. The very same idea relates to extended ranges where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
Lens Coating for Optics
All top teir rifle glass lenses are layered. Lens finish is a crucial element of a rifle when buying high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some optic suppliers also use “HD” or high-definition glass finishings which make the most of different processes, components, chemicals, and polarizations to enhance a wide range of color ranges and viewable target definition through lenses. This high-definition finishing is commonly used with more costly, high density lens glass which decreases light’s ability to refract through the lens glass. Some scope corporations use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often noticeable over objects with well defined shapes as light hits the item from particular angles.
Single Scope Lens Coating Versus Multi-Coating
Various optic lenses can also have different finishes used to them. All lenses normally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Rifle Glass Lens Hydrophobic Covering
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic coating.
Alternatives for Installing Glass on Firearms
Mounting approaches for scopes come in a couple of choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also normally are made in quick release versions which use toss levers which permit rifle operators to rapidly install and dismount the scope.
Scope Mounts with Hex Key Rings
Basic, clamp style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on the tops of rifles. These types of scope mounts use a pair of independent rings to support the scope, and are made from 7075 T6 billet aluminum which are made for far away precision shooting. This form of scope mount is effective for rifle systems which are in need of a resilient, rock solid mount which will not shift regardless of how much the scope is moved or jarring the rifle takes. These are the type of mounts you really want to have for a dedicated scope setup on a reach out and touch someone hunting or competitors firearm that will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to keep the hex screws from backing out after they are mounted securely in place. An example of these rings are the 30mm type from the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be swapped out if they all use a complementary style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type 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 maintaining precision. These types of mounts are useful and handy for rifles which are shipped a lot, to take off the scope glass from the rifle for protection, or for scopes which are chosen for use in between a number of rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day on the range and your pricey optic by resulting in fogging and producing residue within the scope tube. Many optics prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant. Usually, these water resistant 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 moisture avoidance for basic use rifles, unless you intend on taking your rifle aboard a watercraft and are worried about the scope still performing if it is submerged in water and you can still rescue the rifle.
What to Know About Rifle Glass Tube Gas Purging
Another part of preventing the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the scope is less influenced by condition 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 exist. These are good qualities of a decent rifle scope to look for.
