Facts About Rifle Glass
Rifle scopes permit you to specifically align a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be dialed in to account for various environmental factors like wind and elevation to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based upon the sight picture you are viewing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle scopes have around eleven parts which are located internally and outside of the scope body. These parts include the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other components. See all eleven parts of an optic.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the optimal type of rifle optic depends on what type of shooting you plan to do.
About First Focal Plane Glass
First focal plane glass (FFP) come with the reticle before the zoom lens. This triggers the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are minimal
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” equations for their long gun
- Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle
Second Focal Plane Optic Info
Second focal plane optics (SFP) feature the reticle behind the zoom lens. This causes the reticle to remain at the very same overall size in connection with the level of magnification being used. The result is that the reticle dimensions adjust based upon the zoom used to shoot over greater ranges due to the fact that the reticle markings represent various increments which change with the magnification. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These sorts of optics work for:
- Long distance kinds of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots take place within shorter distances and ranges
- Shooters who would like a clearer optic picture without room used up by the bigger FFP reticle
Zoom for Rifle Optics
The amount of magnification a scope provides is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Optics
A single power rifle optic or scope uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust considering that it is a fixed power scope.
Variable Power Lens Glass
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will list the zoom amount in a configuration such as 2-10×32. These numbers mean the magnification of the scope could be set in between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power adjustment is achieved utilizing the power ring part of the scope near the rear of the scope by the eye bell piece.
Scope Power Level and Ranges
Here are some advised scope power levels and the distances where they may be efficiently used. Highly magnified rifle scope glass will not be as beneficial as lower magnification scopes given that too much zoom can be a bad thing. The exact same idea goes for longer ranges where the shooter needs to have sufficient power to see exactly where to properly aim the rifle at the target.
Optic Lens Coating
All modern rifle optic and scope lenses are layered. There are various types and qualities of glass lens finishes. Lens finish is a crucial element of a rifle’s setup when contemplating high-end rifle optics and scope units. The glass lenses are one of the most critical pieces of the optic since they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses shields the lens surface as well as helps with anti glare capabilities from refracted sunshine and color visibility.
Info on Lens Coatings – HD Versus ED
Some scope manufacturers even use “HD” or high-def glass coverings that apply different procedures, polarizations, rare earth compounds, and components to enhance separate colors and viewable target visibility through the lens. This high-definition covering is commonly used with more costly, high density lens glass which lowers light’s opportunity to refract through the lens glass. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often noticeable around objects with hard shapes as light hits the object from certain angles.
Single Glass Lens Coating Versus Multi-Coating
Different optic lenses can likewise have different coverings applied to them. All lenses generally have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
This lens treatment can protect 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 layered lens depends on the scope producer and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
Rifle Optic Lens Anti-water Coating
Water on a scope’s lens does not help with preserving a clear sight picture through an optic whatsoever. Many top of the line and premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Options for Mounting Rifle Optics on Firearms
Mounting options for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also normally can be found in quick release versions which use manual levers which allow rifle shooters to quickly mount and remove the scopes.
Hex Key Rifle Optic Ring Mounts
Standard, clamp style 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long range precision shooting. This type of scope mount is great for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles or are situationally focused.
About Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. The majority of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the glass is less altered by condition alterations and pressure differences from the outdoor environment which might potentially enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
