All About Glass
Rifle scopes allow you to exactly aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through zoom using a set of lenses inside the scope. The scope’s positioning can be dialed in to take into account various ecological elements like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based on the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern rifle optics have about eleven parts which are located inside and outside of the scope. These optic pieces include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other components. See all eleven parts of optics.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the finest type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are low
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. This induces the reticle to remain at the very same size in relation to the quantity of zoom being used. The outcome is that the reticle dimensions change based on the zoom employed to shoot over longer ranges due to the fact that the reticle markings present various increments which change with the zoom 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 measurement. These types of optics are convenient for:
- Far away forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and proximities
- Shooters who prefer a clearer optic sight picture with less room used up by the bigger FFP reticle
Magnification for Rifle Scopes
The amount of scope magnification you need on your scope depends on the style of shooting you wish to do. Nearly every type of rifle optic offers some degree of magnification. The quantity of magnification a scope gives is determined by the dimension, density, and curves of the lens glass inside of the rifle scope. The magnifying level of the optic is the “power” of the scope. This means what the shooter is observing through the scope is magnified times the power element of what can generally be seen by human eyes.
Fixed Single Power Lens Optic Facts
A single power rifle scope and optic uses a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust given that it is fixed.
Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom level in a format like 2-10×32. These numbers indicate the zoom of the scope could be changed in between 2x and 10x power. This additionally involves the power levels in-between 2 and 10. The power adjustment is achieved by operating the power ring component of the scope near the back of the scope by the eye bell.
Glass Power and Ranges
Here are some advised scope power levels and the ranges where they could be effectively used. Consider that high magnification optics will not be as efficient as lower magnification level scope and optics due to the fact that too much magnification can be a negative thing in certain situations. The same idea relates to extended ranges where the shooter needs sufficient power to see exactly where to properly aim the rifle at the target.
Optic Lens Finish
All present day rifle optic lenses are covered. Lens covering is an important element of a rifle when buying high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some rifle glass producers will also use “HD” or high-definition lens coatings which use various procedures, chemical applications, polarizations, and components to enhance separate color ranges and viewable target visibility through the lens. This high-definition finish is commonly used with more costly high density glass which lowers light’s opportunity to refract by means of the lens glass. Some scope producers use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious over objects with well defined shapes as light hits the item from various angles.
Info on Single Coating Versus Multi-Coating
Different optic lenses can likewise have various finishes applied to them. All lenses generally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” coated. This indicates the lens has multiple treatments applied to them. If a lens receives multiple treatments, it can show that a manufacturer is taking multiple actions to fight various environmental factors like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This also does not necessarily imply the multi-coated lens is better than a single covered lens. Being “better” depends on the maker’s lens treatment techniques and the quality of components used in constructing the rifle glass.
Anti-water Rifle Glass Lens Finishing
Water on a lens does not help with retaining a clear sight picture through a scope in any way. Numerous top of the line or premium scope producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to keep a clear, water free sight picture.
Glass Mounting Choices
Installing approaches for scopes can be found in a couple of choices. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also usually come in quick release variations which use toss levers which allow rifle operators to rapidly install and dismount the optics.
Hex Key Rifle Glass Rings
Standard, clamp-on design mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use a pair of detached rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are developed for long distance accuracy shooting. This form of scope mount is good for rifles which need a durable, unfailing mount which will not move no matter just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should get for a specialized scope system on a long distance scouting or hard target interdiction rifle that will pretty much never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used to stop the hex screw threads from wiggling out after they are installed firmly in place. An example of these rings are the 30mm type from Vortex Optics. The set generally costs around $200 USD
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used between numerous rifles or are situationally focused.
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can ruin a day on the range and your highly-priced optic by triggering fogging and producing residue within the scope tube. The majority of optics protect against humidity from entering the optical tube with a series of sealing O-rings which are waterproof. Generally, these scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture content avoidance for basic use rifles, unless you anticipate taking your rifle on boats and are worried about the scope still functioning if it goes over the side and you can still retrieve the gun.
Info Around Rifle Glass Tube Gas Purging
Another part of preventing the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less affected by climate shifts and pressure distinctions from the outside environment which may possibly allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
