What You Need to Know About Optics
Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through zoom by using a set of lenses within the scope. The scope’s positioning can be dialed in to account for separate environmental things like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle optics have around eleven parts which are located inside and externally on the scope body. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. Learn about the eleven parts of optics.
About Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the optimal type of rifle scope is based around what type of shooting you plan on doing.
Info About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based upon the amount of zoom being used. The result is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are small
- Experienced shooters who understand their aim point “hold over” plus “lead” correlations for their firearms
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle behind the magnification lens. This induces the reticle to remain at the exact same size in connection with the amount of zoom being used. The effect is that the reticle dimensions change based on the zoom used to shoot over longer ranges due to the fact that the markings represent distinct increments which differ with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These varieties of glass are beneficial for:
- Long distance types of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who like a clearer optic picture without room taken up by the bigger FFP reticle
Magnification for Rifle Scopes
The amount of scope zoom you need on your glass depends upon the sort of shooting you like to do. Practically every kind of rifle scope offers some amount of zoom. The quantity of magnification a scope offers is identified by the dimension, thickness, and curvatures of the lenses within the rifle optic. The magnification level of the scope is the “power” of the glass. This suggests what the shooter is aiming at through the scope is magnified times the power element of what can usually be seen by human eyes.
Fixed Single Power Lens Scopes
A single power rifle optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change because it is set from the factory.
Adjustable Power Lens Rifle Scope Details
Variable power rifle scopes can be tweaked between magnified levels. The power change is accomplished by using 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 suggested scope power settings and the ranges where they can be successfully used. Keep in mind that high magnification optics and scopes will not be as efficient as lower magnification level scopes due to the fact that too much magnification can be a bad thing. The very same idea applies to longer ranges where the shooter needs to have increased power to see precisely where to properly aim the rifle at the target.
Lens Finishing for Rifle Optics
All modern rifle scope lenses are covered in special coatings. There are different types and qualities of glass finishings. When looking at luxury rifle optical units, Lens covering can be an essential aspect of a rifle. The lenses are among the most important pieces of the optic as they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses protects the lens surface as well as helps with anti glare capabilities from refracted direct sunlight and color visibility.
Details on Lens Coatings – HD Versus ED
Some scope manufacturers also use “HD” or high-definition lens coatings which use different procedures, aspects, chemicals, and polarizations to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Rifle Glass
Different optic lenses can even have different finishes applied to them. All lenses usually have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in lots of types of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering 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 on the scope manufacturer and how much you paid for it.
Some scope makers similarly make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in building the rifle scope.
Optic Lens Hydrophobic Coating
Water on an optical lens does not help with keeping a clear sight picture through an optic at all. Many top of the line or high-end scope makers 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 of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Choices for Installing Rifle Glass on Long Guns
Mounting approaches for scopes are available in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also normally come in quick release versions which use toss levers which permit rifle shooters to quickly install and dismount the glass.
Scope Mounts with Hex Key Rings
Standard, clamp style mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use double individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This kind of scope mount is great for rifle systems which require a durable, hard use mount which will not move no matter just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you really want to have for a devoted optics setup on a far away hunting or hard target interdiction firearm that will seldom need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screws from backing out after they are mounted safely in place. An example of these rings are the 30mm type made by the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle. If they all use a comparable design mount, multiple scopes can often be switched out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving the original sighting settings. These types of mounts are useful and practical for shooting platforms which are carried a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are chosen for use between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Scope Tubes
Another element of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the optic is less influenced by condition shifts and pressure distinctions from the outside environment which could potentially enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
