What You Need to Know About Optics
Rifle scopes enable you to specifically align a rifle at different targets by aligning your eye with the target at range. They accomplish this through zoom by using a series of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of different environmental factors like wind and elevation increases 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 seeing using the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle scopes and optics have about 11 parts which are found inside and externally on the scope body. These parts consist of the rifle scope’s body, lenses, windage turrets, focus rings, and other elements. Learn about the eleven parts of rifle optics.
About Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane a scope has identifies where the reticle or crosshair is located in connection with the scopes magnification. It simply suggests the reticle is situated behind or ahead of the magnification lens of the optic. Selecting the most suitable form of rifle optic is dependent on what form of shooting you intend on undertaking.
First Focal Plane Scope Info
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who know their aim point “hold over” and “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle behind the magnifying lens. This induces the reticle to remain at the exact same dimensions in connection with the level of zoom being used. The final result is that the reticle dimensions alter based on the magnification employed to shoot over lengthier ranges considering the reticle measurements present different increments which vary with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These varieties of glass are useful for:
- Far away styles of shooting where shooters have more time to make ballistic computations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who select a clearer optic picture without room taken up by the enlarged FFP reticle
Rifle Scope Zoom
The amount of scope magnification you need on your optic is based on the style of shooting you choose to do. Almost every kind of rifle glass supplies some degree of zoom. The quantity of magnification a scope offers is established by the size, thickness, and curves of the lens glass within the rifle optic. The magnification of the optic is the “power” of the opic. This implies what the shooter is looking at through the scope is magnified times the power element of what can typically be seen by human eyes.
Info About Fixed Single Power Lens Optics
A single power rifle optic and scope will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change given that it is a fixed power scope.
Adjustable Power Lens Glass
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification degree in a configuration such as 2-10×32. These numbers imply the zoom of the scope could be changed between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power manipulation is achieved by applying the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some recommended scope powers and the ranges where they can be efficiently used. Always remember that higher magnification optics and scopes will not be as efficient as lower powered optics and scopes since too much magnification can be a detractor. The same concept relates to extended ranges where the shooter needs sufficient power to see exactly where to best aim the rifle.
Info on Rifle Scope Lens Coatings
All contemporary rifle scope lenses are covered in special coatings. There are various types and qualities of coverings. Lens coating can be an essential element of a rifle when contemplating luxury rifle optics and scope equipment. The lenses are one of the most essential pieces of the glass as they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses safeguards the lens surface area and also assists with anti glare capabilities from excess direct sunlight and color perception.
HD Versus ED Lenses
Some scope producers also use “HD” or high-def lense coverings which employ different procedures, aspects, polarizations, and chemical applications to extract separate colors and viewable definition through lenses. This high-definition coating is commonly used with increased density lens glass which reduces light’s ability to refract through the lens glass. Some scope brands use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration is often visible around things with well defined outlines as light hits the object from certain angles.
Single Rifle Glass Lens Finish Versus Multi-Coating
Different optic lenses can also have different finishings used to them. All lenses normally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope designer and the amount you spent paying for it. Both the make and cost are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Anti-water Lens Coatings
Water on a scope’s lens doesn’t support retaining a clear sight picture through an optic whatsoever. Numerous top of the line or premium scope producers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner optic lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Rifle Optic Installation Options
Mounting approaches for scopes come in a few options. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release versions which use throw levers which permit rifle shooters to rapidly mount and dismount the optics.
Hex Key Glass Ring Mounts
Normal, 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope mount is wonderful for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. If they all use a similar style mount, several scopes can also be swapped out in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping precision. These types of mounts are useful and beneficial for shooting platforms which are transferred between vehicles a lot, to remove the glass from the rifle for protection, or for aiming systems which are utilized between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Details on Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle glass can ruin a day on the range and your expensive optic by triggering fogging and developing residue inside of the scope’s tube. The majority of scopes prevent humidity from going into the optical tube with a series of sealing O-rings which are water resistant. Usually, these scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are concerned about the optic still working if it goes over the side and you can still find the firearm.
Info Around Rifle Scope Tube Gas Purging
Another element of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the optic is less affected by temperature changes and pressure differences from the external environment which might possibly permit water vapor to leak 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.
