Rifle Glass Details
Rifle scopes enable you to precisely aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s alignment can be dialed in to account for numerous natural elements like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the target. A lot of modern-day rifle optics have about 11 parts which are arranged inside and outside of the scope. These parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle optics.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the best type of rifle scope is based around what type of shooting you plan to do.
Info About First Focal Plane Glass
First focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who understand their target “hold over” and “lead” ratios for their firearm
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots occur within much shorter distances and ranges
- Shooters who prefer a clearer optic sight picture without room taken up by the enlarged FFP reticle
Rifle Scope Magnification
The level of scope zoom you need on your scope is based on the sort of shooting you desire to do. Virtually every kind of rifle glass provides some degree of zoom. The volume of zoom a scope provides is determined by the dimension, density, and curves of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the scope. This suggests what the shooter is aiming at through the scope is magnified times the power element of what can generally be seen by human eyes.
Info on Single Power Lens Rifle Glass
A single power rifle optic or scope comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change because it is a set power scope.
Variable Power Lens Optic Facts
Variable power rifle scopes use variable power levels. The power adjustment is achieved by the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope power levels and the ranges where they may be effectively used. Highly magnified optics will not be as efficient as lower magnification level optics due to the fact that too much zoom can be a bad thing. The same idea goes for extended distances where the shooter needs to have increased power to see exactly where to properly aim the rifle.
Glass Lens Finish
All contemporary rifle glass lenses are coated. Lens coating is a vital element of a rifle system when purchasing high end rifle optics and scope systems.
HD Versus ED Rifle Glass Lens Coatings
Some scope makers also use “HD” or high-definition lens coatings which use different procedures, polarizations, chemicals, and components to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
What to Know About Single Covering Versus Multi-Coating
Various optic lenses can also have different finishings used to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope company and how much you spent for it. Both the make and cost are indicators of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” covered. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can prove that a manufacturer is taking numerous actions to combat various natural elements like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This additionally does not always mean the multi-coated lens is better than a single covered lens. Being “better” is dependent on the maker’s lens treatment techniques and the quality of glass used in building the rifle glass.
Hydrophobic Lens Finishes
Water on an optic’s lens does not improve keeping a clear sight picture through a scope at all. Many top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface of the Steiner scope lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Options for Installing Glass on Long Guns
Installing approaches for scopes can be found in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release versions which use manual levers which permit rifle shooters to quickly mount and dismount the scopes.
Hex Key Glass Ring Mounts
Basic, clamp-on style mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use two independent rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are developed for far away accuracy shooting. This type of scope mount is very good for rifles which require a durable, unfailing mount which will not move despite just how much the scope is moved or abuse the rifle takes. These are the design of mounts you should have for a specialized scope system on a far away scouting or hard target interdiction rifle which will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used to keep the hex screws from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be swapped out if they all use a similar design mount. These types of mounts are handy for rifles which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used between several rifles or are situationally focused.
Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your expensive optic by triggering fogging and creating residue inside of the scope tube. Most scopes prevent humidity from entering the optical tube with a system of sealing O-rings which are water resistant. Normally, these water-resistant optics can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness avoidance for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on boats and are concerned about the optic still performing if it falls overboard and you can still find the rifle.
Gas Purged Optic Tubes
Another element of preventing the buildup of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less impacted by condition shifts and pressure distinctions from the external environment which could possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
