Rifle Glass Facts
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target at range. They do this through magnifying the target by using a series of lenses within the scope. The scope’s positioning can be adjusted to take into account separate environmental aspects like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle optics have around 11 parts which are arranged within and externally on the optic. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, focus rings, and other components. See all eleven parts of a rifle scope.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the finest type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who understand their target “hold over” and also “lead” equations for their weapon
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane glass (SFP) come with the reticle behind the magnification lens. This causes the reticle to remain at the same overall size in relation to the level of magnification being used. The outcome is that the reticle dimensions alter based upon the magnification employed to shoot over longer ranges due to the fact that the reticle markings present various increments which change with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These particular styles of glass are beneficial for:
- Long distance styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within much shorter proximities and ranges
- Shooters who like a clearer optic sight picture without space used up by the larger size FFP reticle
Ins and Outs of Glass Zoom
The measure of scope magnification you need on your optic depends on the type of shooting you wish to do. Nearly every kind of rifle scope provides some degree of magnification. The level of magnification a scope provides is determined by the dimension, thickness, and curvatures of the lens glass within the rifle optic. The magnification level of the optic is the “power” of the glass. This suggests what the shooter is observing through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Rifle Scope Info
A single power rifle scope and optic will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not fluctuate since it is a set power scope.
About Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be adjusted between magnification increments. It will note the zoom level in a configuration such as 2-10×32. These numbers indicate the magnification of the scope could be set in between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power modification is accomplished using the power ring component of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some recommended scope power levels and the ranges where they may be efficiently used. High power scopes will not be as beneficial as lower magnification optics given that too much zoom can be a negative aspect depending on your shooting distance. The same idea goes for longer ranges where the shooter needs adequate power to see where to best aim the rifle at the target.
About Scope Lens Coatings
All top of the line rifle scope and optic lenses are coated. Lens coating can be a vital aspect of a shooting platform when looking at high end rifle optics and scope equipment.
HD Versus ED Optic Lens Coatings
Some glass companies also use “HD” or high-definition lens finishes that use different processes, chemical applications, polarizations, and components to enhance a wide range of colors and viewable target definition through lenses. This high-definition finishing is often used with higher density lens glass which reduces light’s opportunity to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration is often visible around objects with defined shapes as light hits the object from particular angles.
Single Covering Versus Multi-Coating for Rifle Scopes
Different scope lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or covering applied to them before being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in numerous kinds of environments, degrees of light (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope producer and how much you spent on it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. This means the lens has had several treatments applied to the surfaces. If a lens receives multiple treatments, it can show that a producer is taking numerous steps to fight various environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally does not necessarily imply the multi-coated lens will perform better than a single covered lens. Being “better” hinges on the maker’s lens treatment innovation and the quality of components used in building the rifle optic.
What to Know About Hydrophobic Covering
Water on a lens does not help with preserving a clear sight picture through an optic at all. Many top of the line and premium optic producers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the exterior surfaces of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Choices for Installing Optics on Long Guns
Installing approaches for scopes come in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use toss levers which permit rifle operators to rapidly install and dismount the scopes.
Scope Mounts with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long distance precision shooting. This type of scope mount is perfect for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar design mount. These types of mounts come in handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used between several rifles or are situationally focused.
Info on Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. The majority of scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Glass Tubes
Another element of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less altered by temperature level alterations and pressure distinctions from the outdoor environment which could potentially enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
