What You Need to Know About Optics
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by making use of a set of lenses within the scope. The scope’s alignment can be adapted for consideration of separate environmental factors like wind and elevation decreases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern rifle scopes and optics have around eleven parts which are arranged inside and externally on the optic. These parts include the rifle scope’s body, lenses, elevation turrets or dials, objective focus rings, and other parts. See all eleven parts of a rifle optical system.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane a scope has identifies where the reticle or crosshair is located in regard to the optic’s magnifying adjustments. It actually means the reticle is situated behind or ahead of the magnifying lens of the scope. Choosing the most beneficial kind of rifle scope is based on what style of shooting or hunting you plan on doing.
Info on First Focal Plane Scopes
First focal plane glass (FFP) come with the reticle before the zoom lens. This induces the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified range. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the exact same tick at one hundred yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are low
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” equations for their firearm
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane scopes (SFP) include the reticle behind 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 types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots happen within shorter spaces and ranges
- Shooters who want a clearer optic sight picture without space taken up by the bigger FFP reticle
Magnification for Glass
The level of scope magnification you need depends on the style of shooting you desire to do. Practically every type of rifle scope gives some degree of zoom. The quantity of zoom a scope supplies is determined by the diameter, thickness, and curvatures of the lenses within the rifle scope. The zoom of the scope is the “power” of the glass. This denotes what the shooter is aiming at through the scope is magnified times the power factor of what can usually be seen by human eyes.
Fixed Power Lens Rifle Scope Details
A single power rifle optic will have a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change considering that it is set from the factory.
About Adjustable Power Lens Glass
Variable power rifle scopes have adjustable power. It will note the zoom degree in a configuration such as 2-10×32. These numbers suggest the zoom of the scope can be adjusted between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power shift is accomplished by operating the power ring component of the scope near the back of the scope by the eye bell piece.
The Power and Range Correlation of Optics
Here are some suggested scope power settings and the ranges where they could be efficiently used. Keep in mind that high magnification optics will not be as practical as lower powered optics and scopes because excessive zoom can be a bad thing. The very same idea relates to longer ranges where the shooter needs to have sufficient power to see where to properly aim the rifle.
Rifle Optic Lens Finish
All modern rifle scope lenses are layered. There are different types and qualities of glass finishes. When thinking about luxury rifle optical devices, Lens finish can be a very important component of defining the capability of the rifle. The lenses are one of the most significant parts of the glass as they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses shields the lens surface area and improves anti glare from refracted direct sunlight and color perception.
Info on Lens Coatings – HD Versus ED
Some rifle scope companies even use “HD” or high-definition glass finishings which take advantage of different processes, aspects, chemical substances, and polarizations to extract separate color ranges and viewable target definition through the lens. This high-def finishing is commonly used with greater density glass which lowers light’s ability to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious around items with defined outlines as light hits the object from various angles.
Single Rifle Optic Lens Covering Versus Multi-Coating
Different optic lenses can likewise have various finishes applied to them. All lenses normally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while lowering 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 on the scope producer and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Rifle Scope Lens Finish
Water on a scope’s lens does not help with keeping a clear sight picture through a scope in any way. Numerous top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner glass lens so the H2O 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.
Scope Installation Choices
Installing approaches for scopes can be found 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 various types of mounts also usually are made in quick release versions which use manual levers which allow rifle shooters to rapidly mount and dismount the glass.
Glass Mounting Solutions with Hex Key Rings
Basic, clamp style mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on rifles. These forms of scope mounts use a pair of detached rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This type of scope mount is excellent for rifles which need to have a resilient, unfailing mount which will not shift no matter how much the scope is moved about or jarring the rifle takes. These are the type of mounts you really want to have for a devoted scope setup on a long distance scouting or competitors rifle that will rarely need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used to stop the hex screw threads from backing out after they are mounted safely in position. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set generally costs around $200 USD
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a comparable design mount, several scopes can also be swapped in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while keeping the original sighting settings. These types of mounts come in practical for rifles which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for optics which are employed in between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. The majority of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Optic Tubes
Another part of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently occupied by the gas, the glass is less altered by temperature changes and pressure differences from the outside environment which may possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
