What You Need to Know About Rifle Glass
Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target over a distance. They do this through zoom by using a series of lenses inside the scope. The scope’s alignment can be adapted for consideration of numerous ecological things like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes have around 11 parts which are arranged within and outside of the optic. These scope parts include the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other components. Learn about the eleven parts of optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has decides where the reticle or crosshair lies in regard to the scopes magnification. It literally implies the reticle is located behind or before the magnifying lens of the scope. Picking out the most suitable sort of rifle glass depends upon what kind of hunting or shooting you anticipate undertaking.
First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who understand their target “hold over” and also “lead” correlations for their firearms
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle to the rear of the zoom 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 kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within much shorter ranges and spaces
- Shooters who like a clearer optic picture without room taken up by the bigger FFP reticle
About Glass Magnification
The quantity of zoom a scope offers is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Fixed Single Power Lens Glass
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 and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate since it is set from the factory.
Variable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified settings. The power modification is achieved by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power levels and the ranges where they may be efficiently used. Bear in mind that high power optics and scopes will not be as efficient as lower powered optics because increased magnification can be a detractor. The same relates to longer ranges where the shooter needs adequate power to see where to best aim the rifle at the target.
Rifle Optic Lens Finish
All current rifle glass lenses are covered. Lens finishing is a crucial aspect of a rifle system when buying high end rifle optics and scope setups.
HD Versus ED Lenses
Some rifle glass makers also use “HD” or high-def lense coverings that use various processes, chemical applications, polarizations, and aspects to extract separate color ranges and viewable target definition through lenses. This high-definition coating is often used with more costly, high density lens glass which reduces light’s opportunity to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often visible over items with well defined shapes as light hits the item from particular angles.
Single Rifle Glass Lens Finishing Versus Multi-Coating
Different optic lenses can even have different finishings applied to them. All lenses generally have at least some type of treatment or finishing 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 is part of the finely tuned optic. It must have a covering placed on it so that it will be optimally usable in many types of environments, degrees of light (full light VS shade), and other shooting conditions.
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 optic. The quality of a single coated lens depends upon the scope company and how much money you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers similarly make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Lens Coatings
Water on a lens doesn’t improve retaining a clear sight picture through a scope in any way. Numerous top of the line or high-end scope producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the surface area of the Steiner scope lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Options for Installing Rifle Optics on Long Guns
Mounting approaches for scopes are available in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use toss levers which allow rifle operators to quickly mount and dismount the scope.
Hex Key Optic Ring Mounts
Basic, clamp-on type mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use a pair of separate rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are designed for long distance precision shooting. This kind of scope mount is very good for rifles which need a long lasting, hard use mount which will not shift no matter just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you really want to have for a specialized optics setup on a long distance scouting or hard target interdiction rifle that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screw threads from backing out after they are installed tightly in position. An example of these rings are the 30mm style from Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a complementary style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving the original sighting settings. These types of mounts come in convenient for shooting platforms which are transferred a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are used in between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Info on Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your pricey optic by triggering fogging and producing residue inside of the scope tube. Most scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another part of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the glass is less affected by temperature changes and pressure differences from the external environment which might possibly permit 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.
