Information About Rifle Glass
Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target at range. They do this through zoom by utilizing a series of lenses within the scope. The scope’s alignment can be adjusted to take into account varied ecological considerations like wind speed and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle scopes have about 11 parts which are located inside and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other parts. See all eleven parts of a rifle scope.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the optimal type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Scopes
First focal plane optics (FFP) feature the reticle before the magnifying lens. This causes 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 range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at 100 yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who understand their aim point “hold over” as well as “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Optic Info
Second focal plane glass (SFP) include the reticle behind the magnifying lens. This causes the reticle to remain at the same overall size in connection with the amount of zoom being used. The final result is that the reticle measurements adapt based upon the magnification used to shoot over greater distances considering the reticle markings present different increments which differ with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These kinds of scopes are handy for:
- Far away kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who desire a clearer optic sight picture with less area used up by the bigger FFP reticle
Zoom for Scopes
The extent of scope zoom you need on your scope depends upon the type of shooting you desire to do. Pretty much every type of rifle scope offers some level of zoom. The amount of magnification a scope supplies is determined by the size, density, and curvatures of the lens glass inside of the rifle optic. The magnification of the scope is the “power” of the glass. This indicates what the shooter is looking at through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Power Lens Glass Details
A single power rifle scope comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust given that it is a fixed power scope.
Adjustable Power Lens Scopes
Variable power rifle scopes use enhanced power. The power adjustment is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Optics
Here are some advised scope power levels and the ranges where they may be effectively used. Always remember that higher power optics and scopes will not be as practical as lower powered optics and scopes because too much magnification can be a bad thing. The exact same idea applies to extended distances where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
Details on Glass Lens Finish
All state-of-the-art rifle glass lenses are covered. Lens finish is an important aspect of a rifle when looking into high end rifle optics and scope systems.
About Rifle Glass Lens Coatings – HD Versus ED
Some rifle scope producers even use “HD” or high-def lens coverings that employ different processes, polarizations, components, and chemicals to extract a wide range of colors and viewable definition through lenses. This high-def finishing is frequently used with higher density lens glass which decreases light’s chance to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration may be noticeable over objects with hard shapes as light hits the item from particular angles.
Info on Single Finish Versus Multi-Coating
Various optic lenses can also have various coatings applied to them. All lenses usually have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while lowering 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 producer and how much money you spent paying for it. Both are indicators of the lens quality.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This indicates the lens has had numerous treatments applied to them. If a lens receives numerous treatments, it can prove that a maker is taking multiple steps to fight different environmental elements like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally doesn’t always mean the multi-coated lens is better than a single coated lens. Being “much better” depends on the manufacturer’s lens treatment solutions and the quality of glass used in building the rifle scope.
Hydrophobic Lens Coverings
Water on a lens does not improve preserving a clear sight picture through an optic in any way. Lots of top of the line or premium scope makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the surface area of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Rifle Glass on Firearms
Installing approaches for scopes can be found in a few choices. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release variations which use toss levers which permit rifle shooters to quickly mount and dismount the scopes.
Hex Key Scope Ring Mounting Solutions
Standard, clamp style mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use two independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is very good for rifle systems which are in need of a resilient, rock solid mount which will not shift no matter how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should get for a dedicated optics system on a long distance hunting or hard target interdiction rifle that will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the screws to prevent the hex screw threads from backing out after they are mounted securely in place. An example of these mounting rings are the 30mm type from the Vortex Optics company. The set typically costs around $200 USD
Optic Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. If they all use a similar style mount, several scopes can often be swapped out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving precision. These kinds of mounts come in practical for rifles which are moved around a lot, to remove the optic from the rifle for protection, or for optics which are chosen for use in between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can mess up a day on the range and your expensive optic by causing fogging and developing residue within the scope’s tube. Most optics protect against humidity from going into the optical tube with a system of sealing O-rings which are waterproof. Typically, these water resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness prevention for basic use rifles, unless you intend on taking your rifle aboard a watercraft and are worried about the optic still working if it goes over the side and you can still rescue the firearm.
Gas Purged Rifle Glass Tubes
Another part of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the glass is less influenced by temperature shifts and pressure variations from the external environment which may potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
