All About Optics
Rifle scopes permit you to specifically align a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by employing a set of lenses inside the scope. The scope’s alignment can be adapted to take into account many natural considerations like wind speed and elevation increases or decreases to make up 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 via the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle optics have around eleven parts which are located inside and outside of the scope body. These scope parts include the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Scopes
First focal plane glass (FFP) come with the reticle before the magnifying lens. This induces the reticle to increase in size based on the extent of zoom being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who know their target “hold over” and also “lead” relationships for their firearm
- Shooters who do not mind the reticle is enlarged and occupies more visual sight space than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle behind the magnification lens. This causes the reticle to stay at the exact same dimensions in connection with the amount of zoom being used. The outcome is that the reticle measurements adjust based on the zoom applied to shoot over lengthier distances given that the reticle markings present different increments which vary with the magnification level. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These sorts of scopes are useful for:
- Far away kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots occur within shorter distances and ranges
- Shooters who want a clearer optic sight picture with less space used up by the larger sized FFP reticle
Magnification for Optics
The measure of scope zoom you need on your glass is based on the form of shooting you want to do. Virtually every style of rifle glass delivers some level of zoom. The quantity of zoom a scope offers is established by the dimension, density, and curvatures of the lenses within the rifle scope. The magnification of the scope is the “power” of the scope. This suggests what the shooter is observing through the scope is amplified times the power element of what can normally be seen by human eyes.
Fixed Single Power Lens Scopes
A single power rifle optic uses 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 type of optic can not change given that it is a fixed power optic.
Adjustable Power Lens Scopes
Variable power rifle scopes can be tweaked between magnified settings. The power adjustment is handled by using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some recommended scope power settings and the ranges where they can be efficiently used. High power glass will not be as effective as lower magnification scopes because too much magnification can be a negative aspect depending on your shooting distance. The same concept applies to longer distances where the shooter needs to have increased power to see where to best aim the rifle.
Lens Covering for Glass
All contemporary rifle scope and optic lenses are coated. There are different types and qualities of coverings. When shopping for luxury rifle optical devices, Lens coating can be a significant element of defining the rifle’s capability. The glass lenses are one of the most important pieces of the optic due to the fact that they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses shields the lens surface and also helps with anti glare from excess natural light and color presence.
HD Versus ED Lenses
Some optic suppliers additionally use “HD” or high-definition lens coverings that employ various procedures, rare earth compounds, elements, and polarizations to extract a wide range of color ranges and viewable definition through the lens. This high-def finishing is typically used with greater density lens glass which brings down light’s potential 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 colors are presented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration may be visible over items with defined outlines as light hits the object from various angles.
About Single Finishing Versus Multi-Coating
Different scope lenses can also have different finishings applied to them. All lenses generally have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It needs to have a covering applied to it so that it will be efficiently functional in lots of types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends on the scope maker and the amount you spent on it. Both the manufacturer and amount are indicators of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This means the lens has multiple treatments applied to them. If a lens receives numerous treatments, it can indicate that a producer is taking several actions to combat different natural aspects like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also does not necessarily suggest the multi-coated lens is better than a single layered lens. Being “much better” is dependent on the manufacturer’s lens treatment technology and the quality of glass used in constructing the rifle optic.
Hydrophobic Coating for Glass
Water on an optic’s lens doesn’t assist with keeping a clear sight picture through an optic at all. Lots of top of the line and premium scope manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the exterior surfaces of the Steiner optic lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Options for Installing Glass on Firearms
Installing approaches for scopes come in a few choices. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release versions which use toss levers which enable rifle operators to quickly mount and dismount the scope.
Hex Key Scope Rings
Basic, clamp style mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use double individual rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are made for long distance accuracy shooting. This type of scope mount is ideal for rifle systems which are in need of a durable, rock solid mount which will not move despite how much the scope is moved about or jarring the rifle takes. These are the style of mounts you really want to have for a faithful scope system on a far away scouting or interdiction firearm that will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used to keep the hex screw threads from wiggling out after they are installed tightly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set normally costs around $200 USD
Rifle Optic Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can often be swapped in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping precision. These kinds of mounts are useful and convenient for rifles which are carried a lot, to take off the scope from the rifle for protection, or for aiming systems which are chosen for use in between multiple rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It usually costs around $250 USD
Info on Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your pricey optic by triggering fogging and producing residue inside of the scope tube. Many scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Scope Tubes
Another part of avoiding the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is currently taken up by the gas, the scope is less impacted by climate alterations and pressure distinctions from the outdoor environment which could potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
