What You Need to Know About Glass
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnifying the target using a series of lenses inside the scope. The scope’s alignment can be dialed in to take into account different ecological factors like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of contemporary rifle scopes have about 11 parts which are found internally and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, elevation dials, focus rings, and other elements. See all eleven parts of a rifle optical system.
About Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has identifies where the reticle or crosshair is located in relation to the scopes magnifying adjustments. It literally suggests the reticle is behind or ahead of the magnification lens of the scope. Deciding upon the most desired style of rifle optic is based upon what style of hunting or shooting you anticipate undertaking.
Info on First Focal Plane Glass
First focal plane glass (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who understand their target “hold over” and also “lead” equations for their firearm
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle to the rear of the magnifying lens. This induces the reticle to stay at the same scale in relation to the level of zoom being used. The final result is that the reticle dimensions alter based on the zoom applied to shoot over lengthier ranges since the reticle measurements present various increments which can vary with the zoom level. In the FFP example with the SFP optic, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular styles of optics are handy for:
- Long distance kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and distances
- Shooters who select a clearer optic picture with less space taken up by the enlarged FFP reticle
Scope Magnification
The quantity of magnification a scope offers is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Glass Info
A single power rifle optic will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust since it is a fixed power optic.
Info About Variable Power Lens Glass
Variable power rifle scopes have adjustable power. It will list the magnification level in a configuration like 2-10×32. These numbers indicate the zoom of the scope can be changed in between 2x and 10x power. This also involves the powers in-between 2 and 10. The power adaptation is achieved by operating the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range
Here are some advised scope power levels and the ranges where they may be successfully used. Bear in mind that higher magnification scopes and optics will not be as effective as lower powered optics because increased magnification can be a bad thing. The same relates to longer ranges where the shooter needs adequate power to see precisely where to properly aim the rifle at the target.
Lens Finishing for Rifle Scopes
All current rifle optic lenses are coated. Lens covering is an essential element of a rifle system when looking at high end rifle optics and scope systems.
Details on Lens Coatings – HD Versus ED
Some scope manufacturers additionally use “HD” or high-def lense finishes which employ different procedures, polarizations, elements, and chemicals to extract different colors and viewable target visibility through lenses. This HD covering is typically used with more costly, high density glass which lowers light’s opportunity to refract through the lens glass. Some scope brands use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration can be visible over things with hard edges and outlines as light hits the item from various angles.
Single Optic Lens Finish Versus Multi-Coating
Various scope lenses can even have various coverings applied to them. All lenses generally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It must have a coating put on it so that the lens will be optimally usable in lots of types of environments, degrees of light (full VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less advantageous 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 just how much you spent for it. The scope’s maker and cost are signs of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of materials used in building the rifle scope.
Hydrophobic Lens Covering
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic covering.
Rifle Optic Installing Options
Mounting options for scopes are available in a few options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also normally are made in quick release variations which use throw levers which allow rifle operators to rapidly mount and dismount the glass.
Hex Key Optic Rings
Standard, clamp design 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 is designed for long distance accuracy shooting. This type of scope install is fine for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Rings
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining precision. These types of mounts are useful and beneficial for shooting platforms which are transferred a lot, to remove the scope from the rifle for protection, or for optics which are used between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It generally costs around $250 USD
Info on Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope’s tube. Many optics protect against moisture from getting in the optical tube with a system of sealing O-rings which are water resistant. Generally, these scopes can be immersed underneath 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 basic use rifles, unless you intend on taking your rifle aboard a watercraft and are worried about the optic still functioning if it goes over the side and you can still rescue the firearm.
About Rifle Scope Tube Gas Purging
Another component of preventing the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the glass is less impacted by climate shifts and pressure differences from the external environment which could potentially enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
