All About Optics
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target at range. They do this through zoom by utilizing a set of lenses within the scope. The scope’s alignment can be adjusted to account for different ecological considerations like wind speed and elevation increases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are viewing using the scope as you align the scope’s crosshair or reticle with the target. Many contemporary rifle scopes have about eleven parts which are found inside and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle optics.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the finest type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Glass
First focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the identical tick at 100 yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are marginal
- Experienced shooters who understand their aim point “hold over” as well as “lead” relationships for their firearm
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight space than a SFP reticle
Second Focal Plane Optic Info
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance types of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within much shorter ranges and distances
- Shooters who desire a clearer optic picture without room used up by the enlarged FFP reticle
Zoom for Rifle Optics
The measure of scope zoom you need depends on the type of shooting you wish to do. Pretty much every style of rifle glass offers some level of magnification. The level of zoom a scope offers is determined by the size, density, and curvatures of the lenses within the rifle optic. The zoom of the scope is the “power” of the opic. This means what the shooter is observing through the scope is magnified times the power factor of what can normally be seen by human eyes.
Info About Fixed Single Power Lens Rifle Scopes
A single power rifle optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust given that it is a fixed power scope.
Info on Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some advised scope power levels and the ranges where they may be successfully used. High power glass will not be as beneficial as lower powered scopes considering that too much magnification can be a bad thing. The exact same idea relates to longer distances where the shooter needs to have enough power to see exactly where to properly aim the rifle at the target.
Details on Rifle Optic Lens Finishes
All present day rifle optic and scope lenses are coated. Lens finish can be a crucial element of a rifle system when purchasing high end rifle optics and scope systems.
About Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens finishes which use different techniques, polarizations, chemicals, and elements to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Rifle Scopes
Various optic lenses can likewise have various finishings applied to them. All lenses generally have at least some type of treatment or finishing used to them prior to 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 beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Scope Lens Covering
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic anti-water finish.
Alternatives for Mounting Rifle Optics on Long Guns
Installing options for scopes can be found in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also normally are made in quick release variations which use throw levers which permit rifle shooters to rapidly mount and dismount the scope.
Hex Key Rifle Glass Ring Mounting Solutions
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 two separate rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope install is wonderful for rifles which require a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Optic Mounting Solutions with Quick-Release Cantilever Rings
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 transported a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by bringing about fogging and creating residue inside of the scope tube. The majority of scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Glass Tubes
Another element of avoiding the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the optic is less affected by condition alterations and pressure differences from the outside environment which could possibly enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
