Facts About Optics
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a range. They accomplish this through zoom by utilizing a set of lenses inside the scope. The scope’s positioning can be dialed in to account for many ecological aspects like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the target. Most modern rifle optics have around eleven parts which are located within and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, modification turrets, focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has determines where the reticle or crosshair is located in regard to the optic’s magnification. It actually means the reticle is behind or in front of the magnifying lens of the scope. Deciding on the most reliable sort of rifle optic is dependent on what sort of shooting you intend on undertaking.
First Focal Plane Optics
First focal plane glass (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the amount of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. As an example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the same tick at one hundred yards using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who have an idea for their target “hold over” and “lead” relationships for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane scopes (SFP) feature the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the exact same scale in relation to the level of zoom being used. The final result is that the reticle dimensions shift based on the zoom employed to shoot over longer distances considering the markings present various increments which differ with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick. These styles of scopes work for:
- Long distance styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who like a clearer optic picture without room taken up by the bigger FFP reticle
Ins and Outs of Optic Zoom
The amount of zoom a scope provides is figured out by the diameter, density, 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 zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not change given that it is fixed.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. It will list the magnification amount in a format like 2-10×32. These numbers indicate the magnification of the scope can be set in between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power manipulation is achieved using the power ring part of the scope near the rear of the scope by the eye bell piece.
Scope Power and Range Correlation
Here are some recommended scope powers and the ranges where they could be effectively used. High power optics will not be as effective as lower magnification rifle scope glass because too much zoom can be a bad thing. The same applies to longer distances where the shooter needs to have increased power to see precisely where to best aim the rifle.
Details on Lens Covering
All contemporary rifle glass lenses are layered. Lens finish can be an essential aspect of a shooting platform when purchasing high end rifle optics and scope setups.
HD Versus ED Lenses
Some rifle scope producers even use “HD” or high-definition lense coverings which use different procedures, rare earth compounds, polarizations, and aspects to draw out a wide range of color ranges and viewable target visibility through lenses. This high-definition finishing is typically used with higher density glass which reduces light’s opportunity to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible over things with hard shapes as light hits the item from certain angles.
Optic Lens Single Finishing Versus Multi-Coating
Various scope lenses can even have various coatings applied to them. All lenses generally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It must have a coating put on it so that the lens will be efficiently functional in numerous types of environments, degrees of sunlight (full VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. 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 optic. The quality of a single coated lens depends upon the scope manufacturer and the amount you spent on it. Both the make and cost are indications of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. This implies the lens has several treatments applied to the surfaces of the glass. If a lens receives several treatments, it can prove that a manufacturer is taking multiple actions to combat different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also does not necessarily imply the multi-coated lens is much better than a single layered lens. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Rifle Glass Lens Finishing
Water on an optic’s lens does not support keeping a clear sight picture through an optic whatsoever. Numerous top of the line and premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the surface of the Steiner optic lens so the water particles can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Scopes on Long Guns
Mounting solutions for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also usually are made in quick release variations which use toss levers which enable rifle operators to quickly install and dismount the optics.
Optic Mounts with Hex Key Rings
Standard, clamp-on type mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use double separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This form of scope mount is ideal for rifle systems which need to have a resilient, hard use mount which will not change no matter how much the scope is moved or abuse the rifle takes. These are the style of mounts you should get for a devoted scope setup on a long distance hunting or competitors firearm that will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from backing out after they are installed firmly in position. An example of these mounting rings are the 30mm type from the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and connect it to a different rifle. Numerous scopes can also be switched out if they all use a compatible design mount. These types of mounts are convenient for rifles which are carried a lot, to swap out the optic from the rifle for protection, or for optics which are used in between numerous rifles.
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by bringing about fogging and producing residue inside of the scope tube. Most scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
About Rifle Glass Tube Gas Purging
Another element of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less impacted by temp changes and pressure differences from the outdoor environment which might potentially allow 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 seek out.
