Info About Optics
Rifle scopes allow you to exactly aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification by employing a set of lenses within the scope. The scope’s positioning can be adjusted for the consideration of many environmental aspects like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the target. Many modern rifle optics have about eleven parts which are found within and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other components. Learn about the eleven parts of rifle optics.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the finest type of rifle glass is based around what type of shooting you plan to do.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who understand their aim point “hold over” and “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of 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 styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and distances
- Shooters who desire a clearer optic sight picture with less area taken up by the enlarged FFP reticle
About Glass Zoom
The amount of scope zoom you require depends upon the type of shooting you wish to do. Nearly every type of rifle optic supplies some degree of zoom. The quantity of magnification a scope delivers is determined by the dimension, thickness, and curves of the lenses inside of the rifle scope. The magnifying level of the scope is the “power” of the glass. This suggests what the shooter is looking at through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Fixed Power Lens Scopes
A single power rifle scope will have a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate because it is set from the factory.
Adjustable Power Lens Glass Details
Variable power rifle scopes use variable power levels. The power change is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Rifle Scopes
Here are some recommended scope power settings and the distances where they could be effectively used. Highly magnified glass will not be as useful as lower magnification level scopes because too much zoom can be a bad thing. The same idea relates to longer distances where the shooter needs enough power to see exactly where to properly aim the rifle.
Rifle Glass Lens Finish
All contemporary rifle glass lenses are layered. Lens coating can be a crucial aspect of a shooting system when looking at high end rifle optics and scope systems.
HD Versus ED Lens Coatings
Some scope makers likewise use “HD” or high-definition lens coatings which use different techniques, chemicals, polarizations, and elements to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Glass Lens Single Coating Versus Multi-Coating
Various scope lenses can also have various coverings applied to them. All lenses generally have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It must have a coating placed on it so that the lens will be efficiently usable in many kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope producer and the amount you paid for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers likewise make it a point to specify if their optic lenses are covered or “multi” coated. This indicates the lens has had numerous treatments applied to them. If a lens receives multiple treatments, it can show that a maker is taking numerous actions to combat various natural factors like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This also does not necessarily suggest the multi-coated lens will perform better than a single layered lens. Being “better” is dependent on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle optic.
Anti-water Glass Lens Finishing
Water on an optical lens does not support retaining a clear sight picture through a scope in any way. Lots of top of the line or high-end optic producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the surface area of the Steiner optic lens so the H2O particles can not bind to it or develop surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Options for Mounting Rifle Glass on Long Guns
Installing options for scopes can be found in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also generally can be found in quick release versions which use toss levers which permit rifle operators to rapidly mount and remove the scopes.
Hex Key Optic Ring Mounts
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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long range precision shooting. This type of scope mount is fine for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Several scopes can even be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifles which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used between several rifles or are situationally focused.
Info on Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can destroy a day of shooting and your highly-priced optic by inducing fogging and developing residue inside of the scope’s tube. The majority of scopes prevent humidity from going into the optical tube with a system of sealing O-rings which are waterproof. Generally, these water resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture content prevention for basic use rifles, unless you anticipate taking your rifle on your motorboat and are concerned about the optic still functioning if it goes over the side and you can still salvage the rifle.
Scope Gas Purging
Another part of preventing the accumulation of wetness within the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less influenced by temperature alterations and pressure differences from the external environment which might possibly allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
