What You Need to Know About Glass
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by utilizing a series of lenses within the scope. The scope’s alignment can be adapted for consideration of different environmental considerations like wind and elevation decreases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have around 11 parts which are located internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, windage dials, focus rings, and other components. See all eleven parts of a rifle optical system.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the best type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are minor
- Experienced shooters who understand their target “hold over” as well as “lead” relationships for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the magnification lens. This causes the reticle to stay at the very same overall size in connection with the level of magnification being used. The end result is that the reticle dimensions alter based upon the zoom chosen to shoot over lengthier distances considering that the markings represent distinct increments which can vary with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular types of scopes work for:
- Long distance kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who choose a clearer optic sight picture without room taken up by the larger sized FFP reticle
Zoom for Scopes
The quantity of scope magnification you require depends upon the kind of shooting you plan to do. Just about every type of rifle glass provides some degree of magnification. The volume of zoom a scope provides is identified by the size, thickness, and curvatures of the lens glass within the rifle optic. The magnification level of the optic is the “power” of the opic. This signifies what the shooter is aiming at through the scope is magnified times the power element of what can generally be seen by human eyes.
Fixed Power Lens Rifle Optic Facts
A single power rifle optic uses a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust given that it is a fixed power scope.
Info About Variable Power Lens Optics
Variable power rifle scopes can be changed between magnification levels. It will note the magnification amount in a format like 2-10×32. These numbers suggest the magnification of the scope can be changed between 2x and 10x power. This also includes the powers in-between 2 and 10. The power modification is accomplished by making use of the power ring component of the scope near the rear of the scope by the eye bell.
Optic Power Level and Ranges
Here are some advised scope power levels and the ranges where they may be successfully used. High power scopes will not be as efficient as lower magnification level optics given that too much zoom can be a negative aspect depending on your shooting distance. The same idea goes for longer distances where the shooter needs to have increased power to see where to best aim the rifle at the target.
Details on Glass Lens Coverings
All current rifle scope lenses are layered. Lens covering is an important aspect of a rifle system when looking at high end rifle optics and scope systems.
About Lens Coatings – HD Versus ED
Some rifle scope suppliers even use “HD” or high-def lens finishes which apply various processes, aspects, rare earth compounds, and polarizations to enhance separate colors and viewable target definition through the lens. This high-definition covering is typically used with more costly, high density lens glass which decreases light’s opportunity to refract through the lens glass. Some scope suppliers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be obvious over objects with hard outlines as light hits the object from various angles.
Rifle Optic Lens Single Covering Versus Multi-Coating
Different optic lenses can also have various finishes used to them. All lenses usually have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope producers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Info on Hydrophobic Covering
Water on an optical lens doesn’t help with preserving a clear sight picture through an optic whatsoever. Numerous top of the line or premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the surface area of the Steiner optic lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Optic Installing Options
Installing options for scopes are available in a couple of choices. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also generally are made in quick release versions which use toss levers which permit rifle shooters to rapidly mount and remove the scope.
Hex Key Optic Ring Mounting Solutions
Standard, clamp design mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use two separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are designed for long distance precision shooting. This kind of scope mount is exceptional for rifle systems which need to have a durable, unfailing mount which will not shift despite just how much the scope is moved or abuse the rifle takes. These are the design of mounts you want for a dedicated optics setup on a reach out and touch someone hunting or interdiction long gun that will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from backing out after they are installed firmly in place. An example of these mounting rings are the 30mm style made by the Vortex Optics brand. The set normally costs around $200 USD
Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifles which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used in between several rifles.
Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day on the range and your expensive optic by inducing fogging and producing residue within the scope’s tube. Many scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant. Normally, these scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness avoidance for standard use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on your motorboat and are worried about the scope still working if it is submerged in water and you can still recover the rifle.
Details on Rifle Scope Tube Gas Purging
Another part of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the optic is less affected by temperature shifts and pressure variations from the external environment which could potentially allow water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
