What You Need to Know About Rifle Glass
Rifle scopes permit you to specifically aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnification by employing a set of lenses within the scope. The scope’s positioning can be adapted to account for many ecological elements like wind and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the target. The majority of modern-day rifle optics have around eleven parts which are located within and externally on the scope. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other parts. See all eleven parts of optics.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has decides where the reticle or crosshair is located relative to the scopes magnifying adjustments. It literally suggests the reticle is located behind or ahead of the magnification lens of the optic. Looking for the most reliable style of rifle glass is based upon what sort of shooting you intend on doing.
First Focal Plane Glass Facts
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This triggers 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 amplified range as they are at the non amplified range. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who recognize their aim point “hold over” and “lead” correlations for their long gun
- Shooters who do not mind the reticle is enlarged and occupies more visual sight area than a SFP reticle
Second Focal Plane Scope Details
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. This triggers the reticle to remain at the exact same dimensions relative to the quantity of zoom being used. The effect is that the reticle dimensions shift based upon the zoom applied to shoot over longer ranges considering the reticle measurements represent distinct increments which can vary with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These kinds of glass work for:
- Long distance kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within much shorter distances and ranges
- Shooters who like a clearer optic sight picture without room used up by the bigger FFP reticle
About Rifle Optic Zoom
The amount of magnification a scope offers is determined 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.
Single Power Lens Scopes
A single power rifle optic will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not adjust because it is a fixed power optic.
Adjustable Power Lens Scope Details
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom level in a format such as 2-10×32. These numbers mean the magnification of the scope can be changed in between 2x and 10x power. This also involves the powers in-between 2 and 10. The power shift is accomplished by employing the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range Correlation of Optics
Here are some recommended scope power levels and the distances where they can be successfully used. High power rifle scope glass will not be as effective as lower powered optics considering that too much zoom can be a bad thing. The same goes for longer ranges where the shooter needs adequate power to see precisely where to best aim the rifle.
Lens Finish for Rifle Scopes
All modern rifle glass lenses are covered. Lens covering is a vital aspect of a rifle system when looking into high end rifle optics and scope systems.
HD Versus ED Rifle Scope Lens Coatings
Some optic suppliers even use “HD” or high-definition lens finishes which use various procedures, rare earth compounds, elements, and polarizations to draw out separate colors and viewable target visibility through the lens. This high-definition finish is frequently used with more costly high density glass which lowers light’s opportunity to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often visible around things with well defined shapes as light hits the object from various angles.
Single Covering Versus Multi-Coating for Rifle Scopes
Different optic lenses can also have different finishes applied to them. All lenses usually have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less useful 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 producers likewise make it a point to define if their optic lenses are coated or “multi” coated. This suggests the lens has several treatments applied to the surfaces of the glass. If a lens gets several treatments, it can prove that a manufacturer is taking several steps to fight various natural factors like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally does not always suggest the multi-coated lens will perform much better than a single layered lens. Being “much better” depends upon the maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
Rifle Scope Lens Hydrophobic Coating
Water on a scope’s lens does not assist with maintaining a clear sight picture through an optic whatsoever. Lots of top of the line or high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior surfaces of the Steiner scope lens so the H2O molecules 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 Installing Alternatives
Mounting options for scopes come in a few choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally are made in quick release variations which use throw levers which permit rifle operators to quickly install and remove the scopes.
Hex Key Scope Ring Mounting Solutions
Basic, clamp style mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a pair of detached rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are designed for far away precision shooting. This kind of scope mount is excellent for rifle systems which require a durable, unfailing mount which will not change no matter just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should get for a specialized optics setup on a long distance hunting or competition firearm which will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount’s screws to stop the hex screws from backing out after they are installed firmly in position. An example of these mounting rings are the 30mm style made by the Vortex Optics company. The set usually costs around $200 USD
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Numerous scopes can even be swapped out if they all use a similar style mount. These types of mounts are convenient for rifles which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between several rifles or are situationally focused.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by bringing about fogging and creating residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Info Around Optic Tube Gas Purging
Another component of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the scope is less affected by temperature changes and pressure variations from the outdoor environment which could possibly allow water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
