Facts About Optics
Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of various natural considerations like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have around 11 parts which are arranged within and outside of the scope. These parts consist of the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other parts. Learn about the eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has identifies where the reticle or crosshair is located in connection with the scopes magnification. It literally suggests the reticle is located behind or before the magnifying lens of the optic. Considering the most ideal style of rifle scope is based on what kind of hunting or shooting you anticipate undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who understand their target “hold over” as well as “lead” equations for their firearms
- Shooters who do not mind the reticle is bigger and uses up more visual sight space than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle to the rear of the magnifying lens. This induces the reticle to remain at the exact same size in connection with the level of zoom being used. The result is that the reticle measurements change based upon the zoom used to shoot over lengthier ranges considering the reticle measurements present various increments which fluctuate with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular styles of optics are convenient for:
- Long distance styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and spaces
- Shooters who prefer a clearer optic sight picture without room used up by the enlarged FFP reticle
Rifle Glass Zoom
The amount of scope zoom you need is based on the type of shooting you wish to do. Virtually every kind of rifle optic gives some amount of zoom. The level of zoom a scope gives is established by the size, thickness, and curvatures of the lens glass within the rifle scope. The zoom of the optic is the “power” of the opic. This suggests what the shooter is checking out through the scope is amplified times the power element of what can generally be seen by human eyes.
Info on Single Power Lens Glass
A single power rifle optic will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate considering that it is a set power scope.
Info on Adjustable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom degree in a format like 2-10×32. These numbers suggest the zoom of the scope could be set between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power adaptation is achieved by making use of the power ring component of the scope near the rear of the scope by the eye bell.
Scope Power and Range Correlation
Here are some suggested scope powers and the ranges where they could be effectively used. High power scopes will not be as effective as lower magnification level optics considering that too much zoom can be a negative aspect depending on your shooting distance. The same relates to longer distances where the shooter needs increased power to see precisely where to properly aim the rifle.
Glass Lens Finishing
All state-of-the-art rifle glass lenses are covered. Lens finish can be a crucial aspect of a shooting system when buying high end rifle optics and scope equipment.
HD Versus ED Lenses
Some rifle glass companies will also use “HD” or high-def lens finishings that make the most of various procedures, rare earth compounds, elements, and polarizations to draw out different color ranges and viewable definition through the lens. This high-definition covering is typically used with more costly high density glass which decreases light’s capability to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be noticeable over things with hard outlines as light hits the object from various angles.
Single Covering Versus Multi-Coating for Rifle Scopes
Various optic lenses can even have different coatings applied to them. All lenses usually have at least some kind of treatment or covering applied to them before they are used in a rifle scope or optic assembly. This is since the lens isn’t just a raw piece of glass. 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 sunshine (full light VS shade), and other shooting conditions.
This lens treatment can offer protection to 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 layered lens depends on the scope maker and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This means the lens has had several treatments applied to the surfaces of the glass. If a lens receives several treatments, it can indicate that a producer is taking several steps to fight different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic finishing. This also does not necessarily indicate the multi-coated lens will perform better than a single covered lens. Being “better” depends upon the maker’s lens treatment technology and the quality of products used in building the rifle optic.
Rifle Glass Lens Hydrophobic Finish
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic coating.
Rifle Glass Installation Options
Mounting solutions for scopes can be found in a couple of choices. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also normally come in quick release variations which use throw levers which permit rifle operators to quickly mount and dismount the scope.
Rifle Optic Mounts with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use two separate rings to support the scope, and are made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This form of scope mount is excellent for rifles which need a resilient, hard use mount which will not change no matter how much the scope is moved or jarring the rifle takes. These are the style of mounts you want for a specialized optics setup on a far away hunting or hard target interdiction firearm which will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to protect against the hex screw threads from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm type made by the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Optic Rings
These types 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 style mount, multiple scopes can often be switched in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining accuracy. These types of mounts come in handy for rifles which are moved around a lot, to remove the optic from the rifle for protection, or for sight systems which are chosen for use in between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your expensive optic by causing fogging and producing residue inside of the scope tube. The majority of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Info on Scope Tube Gas Purging
Another part of preventing the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the scope is less affected by condition shifts and pressure variations from the outside environment which may potentially permit water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
