Facts About Glass
Rifle scopes permit you to exactly aim a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnifying the target by employing a set of lenses inside the scope. The scope’s alignment can be adapted to take into account various environmental aspects like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle optics have about eleven parts which are located inside and externally on the optic. These optic pieces include the rifle scope’s body, lenses, elevation turrets, objective focus rings, and other parts. See all eleven parts of a rifle optical system.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has determines where the reticle or crosshair lies in connection with the optic’s magnification. It literally suggests the reticle is situated behind or before the magnification lens of the scope. Selecting the most ideal style of rifle scope depends on what kind of shooting you anticipate undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the extent of zoom being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. For example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are very little
- Experienced shooters who recognize their target “hold over” and also “lead” equations for their long guns
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle behind the magnification lens. This induces the reticle to remain at the exact same size in relation to the amount of zoom being used. The end result is that the reticle dimensions alter based on the magnification used to shoot over greater ranges considering the reticle markings represent distinct increments which differ with the zoom level. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular types of scopes work for:
- Long distance forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who choose a clearer optic sight picture with less room taken up by the bigger FFP reticle
Zoom for Scopes
The level of scope magnification you need on your glass depends on the type of shooting you intend to do. Practically every kind of rifle optic provides some amount of zoom. The level of zoom a scope supplies is determined by the dimension, density, and curves of the lens glass within the rifle optic. The magnification of the scope is the “power” of the scope. This indicates what the shooter is checking out through the scope is amplified times the power factor of what can generally be seen by human eyes.
Fixed Single Power Lens Rifle Scopes
A single power rifle optic and scope comes with a magnification 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 type of optic can not change because it is a fixed power optic.
Variable Power Lens Rifle Glass Facts
Variable power rifle scopes can be modified between magnified settings. The power change is performed by the power ring part of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Range Correlation
Here are some suggested scope power levels and the distances where they could be efficiently used. High power rifle scope glass will not be as efficient as lower magnification glass because too much magnification can be a negative aspect depending on your shooting distance. The exact same idea relates to longer distances where the shooter needs enough power to see where to best aim the rifle.
Info on Lens Coating
All contemporary rifle scope and optic lenses are layered. There are various types and qualities of lens finishings. When looking at high end rifle scope setups, Lens coating can be a crucial aspect of defining the capability of the rifle. The lenses are one of the most critical pieces of the glass because they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses shields the lens surface area and helps with anti glare capabilities from refracted sunrays and color exposure.
ED Versus HD Optics
Some rifle scope manufacturers will also use “HD” or high-definition glass coatings which employ different procedures, rare earth compounds, aspects, and polarizations to enhance separate color ranges and viewable definition through lenses. This high-def finishing is often used with more costly high density lens glass which lowers light’s chance to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration can be obvious around things with hard outlines as light hits the item from specific angles.
Single Finishing Versus Multi-Coating for Scopes
Various optic lenses can also have various coverings used to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope developer and how much you spent paying for it. Both are indicators of the lens quality.
Some scope manufacturers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Anti-water Covering for Rifle Optics
Water on an optic’s lens doesn’t support maintaining a clear sight picture through an optic in any way. Many top of the line and high-end scope producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the surface of the Steiner scope lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Scope Installation Alternatives
Mounting options for scopes can be found in a couple of options. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically are made in quick release versions which use toss levers which permit rifle operators to quickly install and remove the optics.
Rifle Optic Mounts with Hex Key Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is wonderful for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. If they all use a similar design mount, several scopes can also be switched out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top type Picatinny rail. This lets 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 practical for shooting platforms which are hauled around a lot, to remove the glass from the rifle for protection, or for sight systems which are adopted in between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It typically costs around $250 USD
What to Know About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can spoil a day of shooting and your highly-priced optic by causing fogging and making residue within the scope’s tube. The majority of scopes protect against wetness from getting in the optical tube with a system of sealing O-rings which are waterproof. Normally, these water-resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient moisture content avoidance for conventional use rifles, unless you anticipate taking your rifle aboard a watercraft and are concerned about the optic still performing if it goes over the side and you can still retrieve the firearm.
What to Know About Rifle Glass Tube Gas Purging
Another element of preventing the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the glass is less altered by temperature changes and pressure variations from the external environment which could possibly permit 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.
