Facts About Optics
Rifle scopes allow you to precisely align a rifle at different targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s positioning can be adjusted to take into account numerous natural things like wind speed and elevation to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes have around 11 parts which are found within and on the exterior of the scope. These parts include the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other elements. See all eleven parts of scopes.
About Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane an optic has decides where the reticle or crosshair lies in connection with the optic’s magnifying adjustments. It simply implies the reticle is behind or in front of the magnification lens of the scope. Picking the most ideal sort of rifle scope depends on what kind of shooting or hunting you intend on undertaking.
Info About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are very little
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” correlations for their firearm
- Shooters who don’t mind the reticle is bigger and requires more visual sight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) come with 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 reticle measurement.
- Far away types of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots take place within shorter proximities and ranges
- Shooters who want a clearer optic sight picture with less area used up by the enlarged FFP reticle
Zoom for Rifle Glass
The quantity of zoom a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Glass
A single power rifle scope will have a magnification 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 type of optic can not change since it is set from the factory.
Info About Variable Power Lens Optics
Variable power rifle scopes use enhanced power. The power change is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some advised scope powers and the distances where they can be successfully used. Consider that higher power glass will not be as efficient as lower powered optics due to the fact that too much magnification can be a bad thing. The same relates to longer distances where the shooter needs to have increased power to see exactly where to best aim the rifle.
About Lens Covering
All cutting-edge rifle scope lenses are covered. Lens covering can be an important aspect of a shooting system when buying high end rifle optics and scope equipment.
HD Versus ED Optic Lens Coatings
Some glass suppliers additionally use “HD” or high-definition lens finishes which use various processes, elements, polarizations, and chemicals to enhance a wide range of color ranges and viewable target visibility through lenses. This HD finishing is often used with increased density lens glass which drops light’s potential to refract through the lens glass. Some scope corporations use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around things with defined outlines as light hits the item from particular angles.
Single Rifle Optic Lens Finishing Versus Multi-Coating
Various optic lenses can also have various finishes applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in lots of types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated 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 layered or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Lens Finishing
Water on an optic’s lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the surface of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Rifle Scope Installation Options
Installing approaches for scopes are available in a couple of choices. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also typically come in quick release versions which use throw levers which allow rifle operators to rapidly install and dismount the optics.
Hex Key Rifle Glass Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is wonderful for rifles which require a durable, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Rings
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 also be swapped out if they all use a compatible style mount. These types of mounts are handy for long guns which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used in between several rifles.
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle glass can destroy a day on the range and your pricey optic by inducing fogging and generating residue inside of the scope tube. Most scopes protect against humidity from going into the scope tube with a series of sealing O-rings which are water resistant. Generally, these water-resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture avoidance for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle boating and are concerned about the optic still functioning if it goes over the side and you can still recover the gun.
Gas Purged Rifle Optic Tubes
Another component of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the glass is less impacted by temp alterations and pressure variations from the external environment which might possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
