Facts About Optics
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target over a range. They do this through magnification by employing a set of lenses within the scope. The scope’s alignment can be adapted for consideration of different environmental elements like wind and elevation decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle optics have around eleven parts which are found inside and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, elevation dials, focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has identifies where the reticle or crosshair is located in relation to the scopes zoom. It simply indicates the reticle is located behind or in front of the magnification lens of the optic. Picking out the most suitable style of rifle glass is based upon what type of shooting or hunting you anticipate undertaking.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who understand their aim point “hold over” and also “lead” correlations for their long gun
- Shooters who don’t mind the reticle is enlarged and requires more visual sight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. This induces the reticle to stay at the same scale relative to the volume of magnification being used. The final result is that the reticle dimensions adapt based on the magnification chosen to shoot over lengthier ranges because the markings present different increments which differ with the magnification. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These styles of optics work for:
- Long distance types of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots happen within much shorter ranges and spaces
- Shooters who select a clearer optic picture without area taken up by the enlarged FFP reticle
Details on Rifle Glass Magnification
The quantity of magnification a scope supplies is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Glass
A single power rifle scope and optic uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate because it is set from the factory.
Adjustable Power Lens Rifle Scope Facts
Variable power rifle scopes can be tweaked between magnified levels. The power change is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some suggested scope powers and the distances where they could be successfully used. Highly magnified glass will not be as efficient as lower powered optics since too much zoom can be a negative aspect depending on your shooting distance. The exact same idea goes for longer distances where the shooter needs sufficient power to see precisely where to properly aim the rifle at the target.
Rifle Optic Lens Coating
All modern-day rifle optic lenses are covered. Lens covering is an essential aspect of a shooting system when looking at high end rifle optics and scope systems.
HD Versus ED Lens Coatings
Some glass producers will also use “HD” or high-definition lens coverings that apply different procedures, components, chemicals, and polarizations to enhance separate color ranges and viewable target visibility through the lens. This high-definition covering is frequently used with more costly high density glass which brings down light’s capability to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often visible over things with hard shapes as light hits the object from various angles.
Single Covering Versus Multi-Coating
Various scope lenses can even have various coatings applied to them. All lenses normally have at least some type of treatment or coating 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 becomes part of the carefully tuned optic. It must have a finish applied to it so that the lens will be optimally functional in lots of types of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Lens Finishes
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic coating.
Choices for Installing Optics on Long Guns
Mounting options for scopes come in a few choices. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also usually can be found in quick release versions which use throw levers which enable rifle shooters to quickly install and remove the scope.
Rifle Optic Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range precision shooting. This type of scope mount is fine for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Numerous scopes can also be switched out if they all use a compatible style mount. These types of mounts are handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles or are situationally focused.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. The majority of scopes prevent humidity from entering the optical tube with a system of sealing O-rings which are water resistant. Typically, these water-resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture content prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard watercrafts and are worried about the scope still performing if it is submerged in water and you can still find the gun.
Gas Purged Glass Tubes
Another element of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the optic is less affected by condition changes and pressure variations from the outdoor environment which may potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
