Facts About Glass
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They do this through magnifying the target by using a set of lenses inside the scope. The scope’s positioning can be dialed in for the consideration of different environmental factors like wind and elevation increases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will land based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes and optics have around 11 parts which are located inside and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other components. See all eleven parts of a scope.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has identifies where the reticle or crosshair is located relative to the optic’s magnification. It simply indicates the reticle is behind or before the magnification lens of the scope. Deciding upon the most beneficial kind of rifle glass is based upon what type of shooting you intend on doing.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. For instance, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who have an idea for their aim point “hold over” and “lead” equations for their long guns
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind the magnification 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 measurement.
- Far away types of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots take place within shorter spaces and ranges
- Shooters who prefer a clearer optic picture with less room used up by the bigger FFP reticle
Magnification for Glass
The extent of scope magnification you need on your optic depends on the style of shooting you wish to do. Almost every kind of rifle scope offers some degree of zoom. The level of zoom a scope offers is determined by the dimension, thickness, and curves of the lens glass within the rifle optic. The magnifying level of the optic is the “power” of the glass. This implies what the shooter is aiming at through the scope is amplified times the power factor of what can normally be seen by human eyes.
Single Power Lens Rifle Glass Facts
A single power rifle optic or scope uses 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 magnification of this type of optic can not fluctuate because it is a fixed power optic.
Adjustable Power Lens Scope Details
Variable power rifle scopes use variable power levels. The power adjustment is handled by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Glass
Here are some advised scope power settings and the ranges where they may be effectively used. Highly magnified glass will not be as beneficial as lower magnification level glass given that too much zoom can be a negative aspect depending on your shooting distance. The exact same idea goes for longer ranges where the shooter needs to have adequate power to see precisely where to properly aim the rifle.
Info on Rifle Scope Lens Finishing
All top of the line rifle optic and scope lenses are covered. Lens covering can be an essential element of a rifle’s setup when considering high end rifle optics and scope setups.
ED Versus HD Optics
Some scope makers likewise use “HD” or high-definition lens coatings which use different processes, elements, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Scope Lens Single Covering Versus Multi-Coating
Various optic lenses can likewise have different finishes used 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 offer protection to the lens from scratches while decreasing 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 manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. This implies the lens has had multiple treatments applied to them. If a lens receives several treatments, it can establish that a maker is taking multiple actions to fight various environmental elements like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally doesn’t necessarily suggest the multi-coated lens will perform better than a single coated lens. Being “better” is dependent on the maker’s lens treatment innovation and the quality of glass used in developing the rifle scope.
Details on Hydrophobic Finish
Water on an optic’s lens doesn’t assist with preserving a clear sight picture through a scope at all. Lots of top of the line or high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Rifle Scope Mounting Options
Mounting approaches for scopes are available in a few options. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually are made in quick release versions which use throw levers which enable rifle shooters to quickly install and dismount the optics.
Optic Mounts with Hex Key Rings
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 a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is perfect for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and connect it to a different rifle. Several scopes can also be switched out if they all use a similar design mount. These types of mounts come in handy for long guns which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used between several rifles.
Info on Glass 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. Many scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Glass Tubes
Another part of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the scope is less altered by condition changes and pressure variations from the outside environment which might possibly 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.
