Info About Rifle Optics

Rifle scopes permit you to exactly align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by employing a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of varied environmental factors like wind speed and elevation increases or decreases to account for bullet drop.

The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle scopes have about 11 parts which are located within and outside of the scope. These optic pieces include the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other parts. Learn about the eleven parts of optics.

The Varieties of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the perfect type of rifle optic is based around what type of shooting you plan on doing.

About First Focal Plane Scopes

Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:

  • Quick acquisition, long distance types of shooting
  • Shooting scenarios where computations are minor
  • Experienced shooters who have an idea for their aim point “hold over” plus “lead” equations for their rifles
  • Shooters who don’t mind the reticle is enlarged and requires more visual sight area than a SFP reticle

Second Focal Plane Scope Facts

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.

  • Long distance kinds of shooting where shooters have additional time to make ballistic computations
  • Shooting where most of the shots happen within much shorter distances and ranges
  • Shooters who select a clearer optic sight picture without room taken up by the larger size FFP reticle

About Scope Magnification

The quantity of magnification a scope offers is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.

Fixed Single Power Lens Rifle Optics

A single power rifle scope will have a zoom 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 optic can not change considering that it is set from the factory.

Info on Adjustable Power Lens Optics

Variable power rifle scopes can be changed between magnification power levels. These types of scopes will list the zoom amount in a configuration such as 2-10×32. These numbers suggest the magnification of the scope could be changed in between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power adaptation is achieved by employing the power ring part of the scope near the rear of the scope by the eye bell.

The Power Level and Range of Scopes

Here are some advised scope power settings and the ranges where they can be successfully used. Highly magnified glass will not be as beneficial as lower powered scopes considering that too much zoom can be a negative aspect depending on your shooting distance. The exact same idea goes for longer distances where the shooter needs to have sufficient power to see where to properly aim the rifle at the target.

Optic Lens Finish

All modern rifle scope lenses are coated. There are different types and qualities of glass finishes. Lens finish is a crucial element of a rifle when contemplating luxury rifle optics and targeting equipment. The glass lenses are among the most vital pieces of the optic since they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface as well as helps with anti glare capabilities from refracted natural light and color profiles.

HD Versus ED Glass Lens Coatings

Some optic suppliers even use “HD” or high-definition lens finishes which use various procedures, rare earth compounds, components, and polarizations to draw out separate color ranges and viewable target visibility through lenses. This high-definition finishing is normally used with greater density glass which brings down light’s potential to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable around things with hard edges and shapes as light hits the object from specific angles.

Single Optic Lens Covering Versus Multi-Coating

Various optic lenses can also have different coverings applied to them. All lenses typically have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic. Due to the fact that the lens isn’t just 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 lots of kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.

Single covered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can preserve 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 coated lens depends on the scope company and just how much you spent for it. Both are indicators of the lens quality.

Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.

About Hydrophobic Finish

Water on a scope’s lens does not help with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end scope producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior of the Steiner scope lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to preserve a clear, water free sight picture.

Alternatives for Installing Rifle Optics on Long Guns

Mounting approaches for scopes come in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also generally come in quick release versions which use throw levers which allow rifle operators to quickly mount and remove the optics.

Hex Key Scope Ring Mounts

Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope mount is fine for rifles which require a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.

Quick-Release Cantilever Glass Ring Mounts

These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, a number of scopes can also be switched out. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten tightly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These types of mounts come in beneficial for rifles which are hauled around a lot, to remove the scope from the rifle for protection, or for sight systems which are utilized between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It normally costs around $250 USD

Rifle Scope Tube Sealing and Gas Purging

Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by bringing about fogging and producing residue inside of the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof.

Glass Gas Purging

Another element of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the glass is less affected by temperature level alterations and pressure distinctions from the outdoor environment which might potentially permit 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.
