What You Need to Know About Optics
Rifle scopes allow you to exactly align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by utilizing a set of lenses within the scope. The scope’s positioning can be dialed in to take into account different ecological factors like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended target. Most contemporary rifle optics have about 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, objective focus rings, and other parts. See all eleven parts of scopes.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the best type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scopes
First focal plane scopes (FFP) feature the reticle ahead of the magnification lens. This triggers the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the identical tick at 100 yards by using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who know their target “hold over” plus “lead” correlations for their long gun
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
Second Focal Plane Scope Info
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Far away kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who prefer a clearer optic sight picture with less area taken up by the enlarged FFP reticle
About Rifle Scope Magnification
The measure of scope magnification you need on your glass is based on the sort of shooting you want to do. Just about every type of rifle optic supplies some level of magnification. The quantity of zoom a scope gives is identified by the size, thickness, and curvatures of the lens glass inside of the rifle optic. The magnification of the optic is the “power” of the glass. This signifies what the shooter is aiming at through the scope is amplified times the power factor of what can typically be seen by human eyes.
Fixed Single Power Lens Rifle Optics
A single power rifle scope and optic will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not fluctuate because it is a fixed power scope.
Variable Power Lens Scopes
Variable power rifle scopes use variable power levels. The power modification is handled using the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Rifle Scopes
Here are some advised scope powers and the distances where they can be efficiently used. Bear in mind that high power glass will not be as practical as lower powered glass due to the fact that excessive magnification can be a detractor. The same goes for longer ranges where the shooter needs to have enough power to see precisely where to properly aim the rifle.
Info on Lens Coating
All top of the line rifle scope lenses are coated. Lens coating can be a crucial element of a rifle when looking into high end rifle optics and scope systems.
HD Versus ED Lens Coatings
Some rifle glass producers also use “HD” or high-def lense coverings which employ various processes, rare earth compounds, elements, and polarizations to enhance different colors and viewable target definition through lenses. This high-def finish is commonly used with greater density glass which brings down light’s ability to refract through the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable over objects with well defined outlines as light hits the object from certain angles.
Glass Lens Single Finish Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses typically have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic. This is since the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope company and just how much you paid for it. Both are signs of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
What to Know About Anti-water Coating
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finish.
Rifle Glass Installing Choices
Mounting options for scopes can be found in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also normally are made in quick release variations which use manual levers which enable rifle operators to rapidly mount and remove the scope.
Glass Mounting Solutions with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope install is great for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, a number of scopes can often be swapped out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining precision. These kinds of mounts are useful and practical for rifles which are transported a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are used between multiple 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 Scope Tubes
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. A lot of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Scope Tubes
Another element of preventing the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less influenced by temp shifts and pressure differences from the external environment which could potentially enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
