Rifle Glass Information
Rifle scopes permit you to precisely align a rifle at different targets by aligning your eye with the target at range. They do this through magnification by utilizing a set of lenses within the scope. The scope’s alignment can be dialed in to account for numerous natural things like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the target. Most modern rifle scopes and optics have about 11 parts which are found internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, elevation turrets or dials, objective focus rings, and other elements. See all eleven parts of a rifle scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the optimal type of rifle optic is based around what type of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are minor
- Experienced shooters who know their target “hold over” plus “lead” relationships for their weapon
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight room than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who select a clearer optic picture with less room used up by the enlarged FFP reticle
Ins and Outs of Glass Zoom
The amount of magnification a scope supplies is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info About Single Power Lens Optics
A single power rifle scope comes with a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate given that it is a set power scope.
About Adjustable Power Lens Glass
Variable power rifle scopes have adjustable power. It will list the zoom degree in a format like 2-10×32. These numbers mean the zoom of the scope could be set between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power modification is achieved using the power ring component of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Glass
Here are some suggested scope powers and the ranges where they may be efficiently used. Consider that higher magnification glass will not be as efficient as lower magnification level glass since too much magnification can be a detractor. The exact same concept relates to longer ranges where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Scope Lens Covering
All modern rifle optic and scope lenses are coated. There are different types and qualities of lens coverings. Lens coating can be an important aspect of a rifle when contemplating high end rifle optics and scope units. The glass lenses are among the most key pieces of the optic considering that they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses shields the lens surface as well as assists with anti glare from refracted sunlight and color discernibility.
Info on Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens finishings which use various procedures, polarizations, chemicals, and components to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses normally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It must have a coating put on it so that the lens will be efficiently usable in numerous types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering 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 on the scope producer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are coated or “multi” coated. This suggests the lens has had several treatments applied to them. If a lens receives numerous treatments, it can prove that a company is taking several steps to fight different environmental factors like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also doesn’t always indicate the multi-coated lens is much better than a single covered lens. Being “better” depends on the maker’s lens treatment innovation and the quality of glass used in building the rifle scope.
Anti-water Lens Coatings
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic finish which is water repellent.
Optic Installing Options
Installing options for scopes come in a couple of options. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually come in quick release versions which use throw levers which permit rifle shooters to rapidly install and remove the glass.
Rifle Glass Mounting Solutions with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long distance accuracy shooting. This type of scope install is excellent for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a comparable style mount, a number of scopes can also be swapped in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining accuracy. These types of mounts come in handy for rifles which are transferred between vehicles a lot, to remove the scope glass from the rifle for protection, or for scopes which are utilized in between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can spoil a day of shooting and your highly-priced optic by inducing fogging and developing residue within the scope tube. Most scopes protect against wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Normally, these water resistant 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 humidity avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are worried about the optic still working if it is submerged in water and you can still recover the firearm.
Gas Purged Rifle Glass Tubes
Another element of avoiding the buildup of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the scope is less altered by climate alterations and pressure differences from the outside environment which could possibly allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
