All About Glass
Rifle scopes permit you to exactly aim a rifle at various targets by lining up your eye with the target at range. They do this through magnification by employing a set of lenses within the scope. The scope’s positioning can be dialed in for consideration of numerous environmental aspects like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes have about 11 parts which are found within and outside of the scope body. These scope parts include the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of optics.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has establishes where the reticle or crosshair lies in regard to the scopes zoom. It simply suggests the reticle is located behind or in front of the magnification lens of the optic. Looking for the best form of rifle optic depends upon what variety of shooting you plan on doing.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who recognize their target “hold over” plus “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. This triggers the reticle to stay at the very same dimensions in connection with the quantity of zoom being used. The result is that the reticle dimensions alter based upon the zoom applied to shoot over lengthier ranges given that the reticle measurements represent different increments which change with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These sorts of scopes are useful for:
- Long distance kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots occur within shorter proximities and ranges
- Shooters who choose a clearer optic sight picture with less area taken up by the larger size FFP reticle
Zoom for Rifle Glass
The quantity of zoom a scope offers is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Optic Info
A single power rifle scope or optic comes with a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust because it is fixed.
Variable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will note the magnification amount in a configuration such as 2-10×32. These numbers suggest the magnification of the scope could be changed between 2x and 10x power. This always involves the powers in-between 2 and 10. The power modification is accomplished by working with 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 settings and the ranges where they may be successfully used. Highly magnified scopes will not be as effective as lower powered rifle scope glass because too much zoom can be a negative aspect depending on your shooting distance. The same idea relates to longer ranges where the shooter needs adequate power to see exactly where to properly aim the rifle at the target.
Details on Lens Coverings
All contemporary rifle optic and scope lenses are coated. Lens finishing can be a significant aspect of a rifle system when thinking about high end rifle optics and scope systems.
About Lens Coatings – HD Versus ED
Some rifle scope makers also use “HD” or high-def lens finishes that take advantage of various procedures, chemicals, polarizations, and aspects to enhance different color ranges and viewable target definition through lenses. This high-definition coating is commonly used with more costly, high density glass which decreases light’s potential to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around objects with defined outlines as light hits the item from certain angles.
Single Scope Lens Finish Versus Multi-Coating
Various optic lenses can likewise have different finishes used to them. All lenses usually have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope company and just how much you paid for it. Both the make and cost are signs of the lens quality.
Some scope makers likewise make it a point to define if their optic lenses are coated or “multi” covered. This implies the lens has numerous treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can establish that a producer is taking multiple steps to combat various natural factors like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This additionally does not always indicate the multi-coated lens is much better than a single covered lens. Being “much better” hinges on the maker’s lens treatment solutions and the quality of glass used in building the rifle glass.
About Hydrophobic Finish
Water on a scope lens does not assist with maintaining a clear sight picture through an optic whatsoever. Lots of top of the line or high-end optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the surface area of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Rifle Scope Installing Options
Installing approaches for scopes can be found in a few choices. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release versions which use manual levers which permit rifle shooters to rapidly mount and dismount the optics.
Hex Key Rifle Optic Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is excellent 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 Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. Multiple scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping the original sighting settings. These types of mounts come in beneficial for shooting platforms which are carried a lot, to remove the scope glass from the rifle for protection, or for scopes which are used between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It normally costs around $250 USD
Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. The majority of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another element of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the glass is less influenced by temperature shifts and pressure variations from the outdoor environment which might potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
