What You Need to Know About Optics
Rifle scopes enable you to specifically aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by employing a set of lenses within the scope. The scope’s alignment can be adapted to take into account many ecological 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 upon the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern rifle scopes have around 11 parts which are located within and outside of the scope body. These parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other components. See all eleven parts of optics.
About Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the best type of rifle glass is based around what type of shooting you plan to do.
First Focal Plane Scope Facts
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where estimations are very little
- Experienced shooters who understand their target “hold over” plus “lead” equations for their firearm
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight space than a SFP reticle
Info on 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 measurement would be 1/5th of the non “zoom” tick.
- Far away kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who want a clearer optic sight picture with less space used up by the larger size FFP reticle
Rifle Scope Magnification
The amount of zoom a scope provides is figured out 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.
Fixed Single Power Lens Optic Info
A single power rifle optic comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust considering that it is a set power scope.
Adjustable Power Lens Optics
Variable power rifle scopes use enhanced power. The power adjustment is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Optic Power Level and Ranges
Here are some recommended scope power settings and the distances where they may be successfully used. Always remember that higher magnification optics will not be as efficient as lower powered optics since increased magnification can be a detractor. The same relates to extended ranges where the shooter needs to have enough power to see precisely where to best aim the rifle.
Info on Optic Lens Coverings
All cutting-edge rifle scope and optic lenses are coated. Lens finishing can be an important aspect of a rifle system when looking at high end rifle optics and scope setups.
Info on Glass Lens Coatings – HD Versus ED
Some rifle scope producers even use “HD” or high-definition lense finishings that make the most of various processes, elements, chemical substances, and polarizations to enhance a wide range of colors and viewable target visibility through the lens. This high-definition covering is commonly used with higher density lens glass which lowers light’s ability to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration or difference which is also called color distortion or fringing. Chromatic aberration can be noticeable around objects with hard edges and shapes as light hits the object from certain angles.
Details on Single Finishing Versus Multi-Coating
Various optic lenses can likewise have different finishes applied to them. All lenses typically have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can protect 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 covered lens depends upon the scope manufacturer and how much money you spent on it. The scope’s maker and cost are indications of the lens quality.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” coated. This implies the lens has had numerous treatments applied to them. If a lens receives numerous treatments, it can prove that a company is taking multiple steps to combat various natural aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also doesn’t necessarily indicate the multi-coated lens will perform much better than a single coated lens. Being “much better” depends upon the manufacturer’s lens treatment technology and the quality of components used in building the rifle optic.
Rifle Glass Lens Anti-water Covering
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Lots of top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic coating.
Choices for Installing Rifle Scopes on Firearms
Installing options for scopes can be found in a few options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally are made in quick release variations which use throw levers which allow rifle shooters to rapidly install and dismount the glass.
Hex Key Rifle Glass Ring Mounts
Standard, clamp-on design mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use two independent rings to support the scope, and are normally made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is ideal for rifle systems which are in need of a long lasting, hard use mount which will not change despite how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should get for a faithful scope system on a far away scouting or competitors long gun that will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used to prevent the hex screw threads from wiggling out after they are installed securely in position. An example of these rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach 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 convenient for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used between several rifles.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day of shooting and your highly-priced optic by resulting in fogging and producing residue inside of the scope tube. Most optics prevent moisture from going into the optical tube with a series of sealing O-rings which are waterproof. Usually, these water resistant optics can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content avoidance for conventional use rifles for hunting and sporting purposes, unless you anticipate taking your rifle sailing and are worried about the scope still performing if it goes over the side and you can still recover the gun.
Rifle Optic Gas Purging
Another part of avoiding the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the glass is less altered by climate shifts and pressure variations from the outside environment which could possibly allow water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
