Rifle Glass Facts
Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target at range. They do this through magnification by using a set of lenses inside the scope. The scope’s alignment can be adapted to account for different environmental considerations like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based on the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes and optics have around 11 parts which are located inside and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, adjustment dials, focus rings, and other elements. Learn about the eleven parts of optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the optimal type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based on the amount of magnification 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 “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who know their aim point “hold over” as well as “lead” relationships for their long guns
- Shooters who don’t mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who select a clearer optic picture without area used up by the larger sized FFP reticle
Rifle Scope Magnification
The quantity of zoom a scope supplies is figured out 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 Glass
A single power rifle optic and scope uses a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change given that it is fixed.
Variable Power Lens Scope Details
Variable power rifle scopes have adjustable power. It will note the magnification level in a configuration like 2-10×32. These numbers mean the zoom of the scope can be set between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power adjustment is accomplished utilizing the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range of Glass
Here are some advised scope power settings and the ranges where they may be efficiently used. Keep in mind that high magnification optics will not be as effective as lower magnification level optics and scopes due to the fact that too much zoom can be a detractor. The same idea goes for longer distances where the shooter needs to have adequate power to see precisely where to properly aim the rifle at the target.
Rifle Glass Lens Finishing
All modern rifle optic lenses are coated. There are different types and qualities of glass lens finishes. When looking at luxury rifle scope devices, Lens coating can be a crucial element of defining the capability of the rifle. The glass lenses are among the most critical pieces of the optic because they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens exterior and improves anti glare capabilities from refracted sunrays and color visibility.
About Scope Lens Coatings – HD Versus ED
Some optic producers will also use “HD” or high-definition lense finishes which use different procedures, polarizations, elements, and chemicals to extract numerous colors and viewable target definition through lenses. This high-definition coating is typically used with higher density glass which drops light’s opportunity to refract through the lens glass. Some scope makers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious over objects with hard outlines as light hits the item from specific angles.
Single Finish Versus Multi-Coating for Glass
Various optic lenses can likewise have different coverings applied to them. All lenses normally have at least some type of treatment or coating used to them before they are used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing 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 producer and the amount you spent paying for it. The scope’s maker and cost are indications of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Anti-water Scope Lens Finishing
Water on an optic’s lens does not help with retaining a clear sight picture through an optic in any way. Numerous top of the line and premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior of the Steiner optic lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Rifle Scope Mounting Alternatives
Installing solutions for scopes can be found in a few choices. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also normally come in quick release versions which use toss levers which permit rifle shooters to quickly install and dismount the optics.
Glass Mounting Solutions with Hex Key Rings
Basic, clamp type mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These styles of scope mounts use double individual rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are made for far away precision shooting. This form of scope mount is great for rifle systems which require a long lasting, rock solid mount which will not change no matter just how much the scope is moved or abuse the rifle takes. These are the style of mounts you should get for a faithful optics system on a reach out and touch someone hunting or hard target interdiction long gun which will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used to stop the hex screw threads from wiggling out after they are mounted securely in position. An example of these mounting rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. A wide range of scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining the original sighting settings. These types of mounts come in convenient for rifles which are moved around a lot, to take off the glass from the rifle for protection, or for scopes which are utilized between numerous 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 Glass Tubes
Moisture inside your rifle glass can destroy a day of shooting and your costly optic by resulting in fogging and making residue inside of the scope tube. The majority of optics protect against moisture from going into the optical tube with a series of sealing O-rings which are waterproof. Usually, these water resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content avoidance for conventional use rifles, unless you intend on taking your rifle on a boat and are worried about the optic still functioning if it goes overboard and you can still salvage the gun.
Details on Optic Tube Gas Purging
Another element of avoiding the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the scope is less influenced by condition changes and pressure differences from the external environment which may potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
