Facts About Optics
Rifle scopes allow you to precisely aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by making use of a set of lenses within the scope. The scope’s positioning can be adjusted to account for various environmental aspects like wind and elevation to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle optics have around eleven parts which are found inside and externally on the optic. These optic pieces include the rifle scope’s body, lenses, modification dials, focus rings, and other components. See all eleven parts of optics.
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 establishes where the reticle or crosshair lies in regard to the scopes magnification. It actually implies the reticle is behind or ahead of the magnifying lens of the scope. Picking the most desired form of rifle scope is based upon what form of hunting or shooting you plan on undertaking.
First Focal Plane Optic Facts
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers 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 distance as they are at the non magnified range. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” correlations for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within shorter ranges and spaces
- Shooters who desire a clearer optic picture with less space used up by the larger size FFP reticle
Rifle Scope Magnification
The amount of zoom a scope offers is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Optics
A single power rifle scope and optic will have a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate given that it is a fixed power scope.
Info on Variable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification levels. It will list the zoom degree in a configuration like 2-10×32. These numbers imply the zoom of the scope could be adjusted in between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power manipulation is achieved by applying the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Optics
Here are some advised scope powers and the distances where they may be successfully used. Always remember that high magnification optics will not be as efficient as lower powered optics and scopes due to the fact that increased magnification can be a bad thing. The exact same concept goes for longer ranges where the shooter needs sufficient power to see where to properly aim the rifle.
Info on Lens Finish
All top teir rifle glass lenses are layered. Lens covering can be an important aspect of a shooting platform when looking at high end rifle optics and scope equipment.
HD Versus ED Lenses
Some optic manufacturers also use “HD” or high-def glass coverings that take advantage of various processes, components, chemical substances, and polarizations to draw out various color ranges and viewable target definition through lenses. This high-definition finish is frequently used with higher density glass which lowers light’s ability to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration may be obvious over objects with hard shapes as light hits the item from specific angles.
Single Finish Versus Multi-Coating
Various optic lenses can also have various finishings applied to them. All lenses typically have at least some type of treatment or coating applied to them before being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while reducing 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 maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. This suggests the lens has multiple treatments applied to the surfaces. If a lens gets multiple treatments, it can establish that a company is taking several actions to fight different environmental aspects like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This additionally doesn’t necessarily indicate the multi-coated lens will perform much better than a single coated lens. Being “better” depends upon the producer’s lens treatment technology and the quality of products used in creating the rifle optic.
Optic Lens Anti-water Finish
Water on an optical lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and premium optic producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the exterior surfaces of the Steiner scope lens so the water particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Scope Installation Alternatives
Installing approaches for scopes can be found in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also typically are made in quick release versions which use toss levers which enable rifle shooters to quickly install and dismount the scopes.
Rifle Scope Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope install is perfect for rifles which require a resilient, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. A wide range of scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping accuracy. These kinds of mounts are useful and handy for shooting platforms which are transported a lot, to take off the scope glass from the rifle for protection, or for optics which are employed between numerous rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. The majority of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another part of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the glass is less influenced by temperature level changes and pressure distinctions from the external environment which could potentially 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 seek out.
