Information About Glass
Rifle scopes allow you to exactly aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by employing a set of lenses inside the scope. The scope’s positioning can be adapted to account for numerous environmental aspects like wind speed and elevation to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle scopes have around eleven parts which are found within and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the perfect type of rifle scope is based around what type of shooting you plan on doing.
About First Focal Plane Glass
First focal plane optics (FFP) include the reticle before the zoom lens. This induces the reticle to increase in size based upon the extent of zoom being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. For instance, one tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are very little
- Experienced shooters who recognize their target “hold over” and “lead” ratios for their long gun
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) come with 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 reticle measurement.
- Long distance kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and distances
- Shooters who prefer a clearer optic picture without space used up by the larger sized FFP reticle
Ins and Outs of Rifle Glass Zoom
The amount of zoom a scope provides is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Optics
A single power rifle scope will have a zoom number designator like 4×32. This implies 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 fixed.
Variable Power Lens Rifle Glass Facts
Variable power rifle scopes use variable power levels. The power adjustment is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope power settings and the ranges where they may be effectively used. Highly magnified scopes will not be as useful as lower magnification level scopes considering too much magnification can be a bad thing. The exact same idea goes for longer distances where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
Scope Lens Finishing
All modern-day rifle glass lenses are covered. Lens finish can be a crucial element of a shooting system when considering high end rifle optics and scope systems.
HD Versus ED Lenses
Some scope companies will also use “HD” or high-definition lense coatings which make the most of different procedures, rare earth compounds, polarizations, and aspects to extract different color ranges and viewable target visibility through the lens. This HD finishing is often used with greater density glass which lowers light’s ability to refract through the lens glass. Some scope producers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be obvious over objects with hard edges and outlines as light hits the item from certain angles.
Single Covering Versus Multi-Coating
Different scope lenses can also have different finishes applied to them. All lenses usually have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic assembly. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It must have a finish put on it so that the lens will be efficiently usable in numerous types of environments, degrees of light (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope manufacturer and just how much you spent for it. The scope’s maker and cost are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” covered. This implies the lens has multiple treatments applied to the surfaces. If a lens receives numerous treatments, it can establish that a producer is taking numerous steps to combat various environmental elements like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally does not necessarily imply the multi-coated lens is better than a single coated lens. Being “better” depends on the manufacturer’s lens treatment solutions and the quality of components used in constructing the rifle glass.
Anti-water Scope Lens Finish
Water on an optical lens doesn’t improve keeping a clear sight picture through a scope whatsoever. Numerous top of the line and premium scope makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the surface of the Steiner optic lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Choices for Mounting Rifle Optics on Firearms
Installing solutions for scopes can be found in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally can be found in quick release variations which use manual levers which enable rifle operators to rapidly install and remove the glass.
Hex Key Scope Ring Mounting Solutions
Standard, clamp-on type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These kinds of scope mounts use a pair of detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This kind of scope mount is effective for rifle systems which require a durable, rock solid mount which will not change despite just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should get for a faithful optics setup on a long distance hunting or interdiction long gun which will seldom need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to prevent the hex screw threads from backing out after they are mounted tightly in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Multiple scopes can also be swapped out if they all use a similar style mount. These types of mounts are handy for long guns which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between numerous rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle glass can ruin a day on the range and your expensive optic by resulting in fogging and generating residue inside of the scope tube. Most scopes protect against humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Usually, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture avoidance for common use rifles, unless you intend on taking your rifle on a boat and are concerned about the scope still performing if it goes over the side and you can still find the gun.
About Optic Tube Gas Purging
Another part of preventing the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the scope is less impacted by temperature shifts and pressure differences from the external environment which could possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
