Info Optics
Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target at range. They do this through zoom by making use of a series of lenses inside the scope. The scope’s positioning can be dialed in to account for many ecological aspects like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle scopes have about 11 parts which are found inside and outside of the scope. These optic pieces include the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other parts. Learn about the eleven parts of rifle scopes.
About Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has decides where the reticle or crosshair lies relative to the optic’s magnification. It actually implies the reticle is behind or in front of the magnification lens of the optic. Picking out the most reliable form of rifle scope depends upon what variety of hunting or shooting you plan on undertaking.
First Focal Plane Optics
First focal plane scopes (FFP) include the reticle in front of the magnification lens. This causes the reticle to increase in size based on 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 distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the identical tick at one hundred yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are marginal
- Experienced shooters who understand their target “hold over” and “lead” relationships for their rifles
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle to the rear of 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 measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots occur within much shorter proximities and ranges
- Shooters who prefer a clearer optic sight picture without space used up by the larger size FFP reticle
Zoom for Rifle Glass
The amount of zoom a scope offers is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info About Fixed Single Power Lens Glass
A single power rifle scope or optic uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not change because it is a set power scope.
Adjustable Power Lens Rifle Optic Facts
Variable power rifle scopes use enhanced power. The power change is handled by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some advised scope power settings and the distances where they may be successfully used. High power glass will not be as beneficial as lower magnification rifle scope glass given that too much magnification can be a bad thing. The same idea applies to longer distances where the shooter needs to have enough power to see exactly where to properly aim the rifle at the target.
Info on Rifle Optic Lens Finish
All modern rifle glass lenses are coated. Lens coating is a crucial element of a shooting system when buying high end rifle optics and scope equipment.
Details on Rifle Scope Lens Coatings – HD Versus ED
Some optic manufacturers will also use “HD” or high-def lens coverings which make the most of different procedures, chemicals, aspects, and polarizations to enhance different colors and viewable definition through the lens. This HD finishing is often used with more costly, high density lens glass which brings down light’s opportunity to refract through the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED handles how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration can be visible over objects with hard shapes as light hits the item from certain angles.
Glass Lens Single Finish Versus Multi-Coating
Different optic lenses can also have different coverings applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope maker and just how much you paid for it. Both the make and cost are indications of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Anti-water Lens Coverings
Water on a lens does not help with keeping a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic anti-water finish.
Optic Installation Options
Installing options for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use manual levers which permit rifle operators to quickly install and dismount the optics.
Optic 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 two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is fine for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope and attach it to a different rifle. Numerous scopes can even be switched out if they all use a compatible style mount. These types of mounts are handy for long guns which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles.
Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and creating residue inside of the scope tube. Most scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Details on Scope Tube Gas Purging
Another part of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less affected by climate changes and pressure distinctions from the outdoor environment which may potentially enable 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 look for.
