Information About Rifle Glass

Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through magnification by using a set of lenses within the scope. The scope’s alignment can be adjusted to account for numerous ecological aspects like wind speed and elevation to account for bullet drop.

The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle scopes have around 11 parts which are located inside and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other components. Learn about the eleven parts of optics.

About Glass Varieties

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

First Focal Plane Scope Facts

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

  • Quick acquisition, long distance kinds of shooting
  • Shooting scenarios where computations are low
  • Experienced shooters who recognize their aim point “hold over” plus “lead” ratios for their long guns
  • Shooters who do not mind the reticle is enlarged and requires more visual sight space than a SFP reticle

About Second Focal Plane Glass

Second focal plane optics (SFP) include the reticle behind the zoom lens. This causes the reticle to remain at the very same size relative to the quantity of magnification being used. The final result is that the reticle measurements shift based upon the zoom used to shoot over greater distances due to the fact that the reticle measurements represent different increments which can vary with the magnification level. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular types of optics are convenient for:

  • Long distance kinds of shooting where shooters have more time to make ballistic calculations
  • Shooting where most shots happen within much shorter ranges and spaces
  • Shooters who like a clearer optic picture without area used up by the enlarged FFP reticle

Rifle Scope Zoom

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

About Fixed Single Power Lens Rifle Scopes

A single power rifle optic uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate because it is a fixed power optic.

Info About Variable Power Lens Rifle Glass

Variable power rifle scopes can be changed between magnification increments. It will list the zoom degree in a format such as 2-10×32. These numbers imply the magnification of the scope can be set in between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power manipulation is achieved using the power ring component of the scope near the back of the scope by the eye bell.

Rifle Optic Power Level and Ranges

Here are some suggested scope power settings and the distances where they may be efficiently used. High power rifle scope glass will not be as useful as lower magnification level optics considering that too much zoom can be a bad thing. The very same idea goes for extended ranges where the shooter needs to have increased power to see precisely where to properly aim the rifle.

About Rifle Optic Lens Covering

All current rifle optic and scope lenses are coated. Lens covering is a significant aspect of a shooting platform when looking at high end rifle optics and scope setups.

HD Versus ED Lenses

Some rifle glass producers even use “HD” or high-definition lense finishings which use various procedures, polarizations, rare earth compounds, and components to draw out numerous color ranges and viewable target definition through the lens. This high-definition covering is typically used with more costly high density glass which reduces light’s ability to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable over things with hard edges and outlines as light hits the item from specific angles.

Single Finish Versus Multi-Coating

Different scope lenses can also have various coatings applied to them. All lenses normally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. 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 optimally usable in lots of kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.

This lens treatment can offer protection to the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.

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

Hydrophobic Lens Finishes

Water on an optical lens doesn’t support retaining a clear sight picture through a scope whatsoever. Many top of the line or high-end scope producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.

Alternatives for Installing Rifle Glass on Firearms

Mounting approaches for scopes are available 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 various kinds of mounts also usually can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and remove the scope.

Hex Key Rifle 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 two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long distance precision shooting. This type of scope install is excellent for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.

Rifle Scope Mounts with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be swapped out if they all use a similar style mount. These types of mounts come in handy for rifles which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used between several rifles or are situationally focused.

Glass Tube Sealing and Gas Purging

Moisture inside your rifle optic can mess up a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope tube. A lot of scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.

Gas Purged Rifle Scope Tubes

Another part of avoiding the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the glass is less impacted by climate alterations and pressure differences from the outdoor environment which may possibly enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
