Rifle Optic Info
Rifle scopes allow you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom by making use of a series of lenses inside the scope. The scope’s positioning can be adjusted to account for numerous environmental things like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Most modern-day rifle scopes and optics have about eleven parts which are located inside and externally on the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other components. See all eleven parts of a scope.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the optimal type of rifle glass is based on what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This induces 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 amplified distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who recognize their aim point “hold over” plus “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who desire a clearer optic picture with less area used up by the bigger FFP reticle
Details on Optic Magnification
The amount of zoom a scope provides is figured out 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 Rifle Glass
A single power rifle optic and scope uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust because it is a set power scope.
Adjustable Power Lens Rifle Glass Details
Variable power rifle scopes can be tweaked between magnified settings. The power modification is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
Rifle Optic Power Level and Range Correlation
Here are some advised scope powers and the distances where they can be successfully used. Highly magnified glass will not be as useful as lower magnification rifle scope glass considering that too much magnification can be a negative aspect depending on your shooting distance. The same idea applies to longer distances where the shooter needs adequate power to see where to properly aim the rifle at the target.
About Scope Lens Finishing
All top teir rifle scope lenses are layered. Lens finish is an essential element of a rifle when thinking about high end rifle optics and scope setups.
Details on Scope Lens Coatings – HD Versus ED
Some scope suppliers also use “HD” or high-definition lense coatings that apply different procedures, rare earth compounds, aspects, and polarizations to enhance different colors and viewable definition through the lens. This high-definition finishing is commonly used with greater density glass which brings down light’s chance to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often visible around items with defined outlines as light hits the item from various angles.
Rifle Scope Lens Single Covering Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses normally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is since the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in lots of kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while lowering glare and other less advantageous 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 makers likewise make it a point to specify if their optic lenses are covered or “multi” coated. This suggests the lens has had several treatments applied to the surfaces. If a lens gets multiple treatments, it can prove that a producer is taking numerous steps to combat different natural factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This additionally does not necessarily imply the multi-coated lens is much better than a single covered lens. Being “better” is dependent on the producer’s lens treatment technology and the quality of glass used in constructing the rifle optic.
Glass Lens Hydrophobic Finishing
Water on an optic’s lens does not assist with maintaining a clear sight picture through an optic whatsoever. Lots of top of the line or premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface area of the Steiner glass lens so the water molecules can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Options for Mounting Glass on Long Guns
Mounting approaches for scopes can be found in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release variations which use throw levers which permit rifle shooters to quickly mount and dismount the scopes.
Hex Key Optic Ring Mounting Solutions
Standard, clamp style 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 made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is excellent for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be switched out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type 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 come in practical for rifles which are transported a lot, to remove the scope from the rifle for protection, or for optics which are chosen for use in between a number of rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle scope can ruin a day on the range and your pricey optic by inducing fogging and producing residue within the scope tube. A lot of scopes prevent wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Generally, these water resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness avoidance for basic use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are concerned about the scope still working if it goes overboard and you can still find the gun.
Scope Gas Purging
Another element of avoiding the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the optic is less impacted by temperature alterations and pressure differences from the outside environment which may possibly enable 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.
