What You Need to Know About Optics
Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target at range. They do this through magnification by making use of a series of lenses inside the scope. The scope’s positioning can be adapted for consideration of different natural aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes and optics have around eleven parts which are arranged internally and outside of the scope. These parts consist of the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other parts. Learn about the eleven parts of rifle optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the finest type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optics
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 zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non magnified 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 work for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are low
- Experienced shooters who recognize their target “hold over” plus “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) feature 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.
- Long distance kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots take place within shorter distances and ranges
- Shooters who want a clearer optic picture without room used up by the bigger FFP reticle
Zoom for Scopes
The quantity of scope magnification you need is based on the form of shooting you want to do. Pretty much every type of rifle optic gives some level of zoom. The level of magnification a scope provides is established by the size, thickness, and curvatures of the lens glass within the rifle optic. The magnifying level of the scope is the “power” of the opic. This indicates what the shooter is looking at through the scope is magnified times the power factor of what can usually be seen by human eyes.
Single Power Lens Rifle Optics
A single power rifle scope comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change because it is fixed.
Info About Variable Power Lens Rifle Optics
Variable power rifle scopes can be adjusted between magnification levels. It will list the zoom amount in a format like 2-10×32. These numbers indicate the zoom of the scope can be adjusted in between 2x and 10x power. This always includes the powers in-between 2 and 10. The power shift is accomplished by employing the power ring component of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power settings and the distances where they may be effectively used. Consider that high magnification optics will not be as efficient as lower powered optics and scopes because too much zoom can be a detractor. The same goes for longer distances where the shooter needs sufficient power to see precisely where to properly aim the rifle.
About Rifle Glass Lens Finishing
All present day rifle glass lenses are coated. Lens coating can be a crucial element of a rifle’s setup when looking at high end rifle optics and scope setups.
HD Versus ED Rifle Glass Lens Coatings
Some rifle scope manufacturers additionally use “HD” or high-def lense coverings that take advantage of various procedures, chemicals, polarizations, and elements to draw out different colors and viewable target definition through the lens. This high-definition finish is typically used with increased density lens glass which brings down light’s opportunity to refract through the lens glass. Some scope brands use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration may be noticeable around items with defined outlines as light hits the object from various angles.
Rifle Scope Lens Single Covering Versus Multi-Coating
Different optic lenses can also have different coverings used to them. All lenses normally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope developer and how much you spent for it. Both are indicators of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” covered. This implies the lens has numerous treatments applied to them. If a lens receives multiple treatments, it can indicate that a maker is taking multiple steps to fight different environmental elements like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also doesn’t necessarily mean the multi-coated lens will perform much better than a single covered lens. Being “much better” is dependent on the producer’s lens treatment techniques and the quality of glass used in building the rifle scope.
Anti-water Lens Coating
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finish.
Rifle Optic Mounting Alternatives
Installing solutions for scopes come in a couple of options. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also typically are made in quick release variations which use manual levers which permit rifle operators to rapidly install and remove the scopes.
Optic Mounting Solutions with Hex Key Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount is excellent for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between numerous rifles.
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by causing fogging and producing residue inside of the scope tube. The majority of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Info Around Optic Tube Gas Purging
Another part of preventing the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the optic is less influenced by condition shifts and pressure distinctions from the external environment which may possibly permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
