What You Need to Know About Glass
Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through magnification by making use of a set of lenses inside the scope. The scope’s alignment can be dialed in to take into account separate ecological considerations like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the target. The majority of modern rifle scopes have around eleven parts which are found internally and on the exterior of the optic. These parts consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of glass.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the finest type of rifle scope is based on what type of shooting you plan on doing.
Info About First Focal Plane Scopes
First focal plane glass (FFP) feature the reticle before the magnifying lens. This causes the reticle to increase in size based on the amount of zoom 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 without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who recognize their aim point “hold over” as well as “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. This triggers the reticle to stay at the very same scale in relation to the level of magnification being used. The final result is that the reticle dimensions evolve based upon the zoom used to shoot over greater ranges considering the reticle measurements represent distinct increments which fluctuate with the zoom. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These types of scopes are convenient for:
- Long distance forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots take place within much shorter spaces and ranges
- Shooters who desire a clearer optic picture with less area taken up by the bigger FFP reticle
Details on Scope Magnification
The quantity of magnification a scope provides is determined 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.
Fixed Single Power Lens Rifle Optic Info
A single power rifle scope will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not fluctuate since it is set from the factory.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be tweaked between magnified settings. The power change is achieved by making use of 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 distances where they can be successfully used. Keep in mind that high magnification glass will not be as practical as lower magnification level glass due to the fact that increased magnification can be a negative thing in certain situations. The very same idea goes for longer ranges where the shooter needs to have adequate power to see where to best aim the rifle.
About Rifle Scope Lens Covering
All present day rifle scope and optic lenses are covered. Lens coating is an important element of a shooting system when buying high end rifle optics and scope equipment.
HD Versus ED Scope Lens Coatings
Some rifle glass suppliers even use “HD” or high-definition glass finishes which make the most of different procedures, polarizations, aspects, and chemicals to extract various colors and viewable target definition through lenses. This high-definition covering is commonly used with higher density glass which decreases light’s potential to refract by means of the lens glass. Some scope corporations use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often obvious around things with hard edges and outlines as light hits the object from various angles.
Single Rifle Optic Lens Covering Versus Multi-Coating
Various optic lenses can likewise have various coatings used to them. All lenses normally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope manufacturer and the amount you spent on it. Both are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
Rifle Scope Lens Hydrophobic Finishing
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic finishing which is water repellent.
Choices for Installing Rifle Glass on Firearms
Installing options for scopes are available in a couple of choices. There are the basic 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 can be found in quick release variations which use manual levers which enable rifle shooters to quickly mount and remove the optics.
Hex Key Rifle Optic Ring Mounting Solutions
Basic, clamp-on style mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use a pair of separate rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This kind of scope mount is good for rifle systems which need a long lasting, rock solid mount which will not move no matter just how much the scope is moved or abuse the rifle takes. These are the design of mounts you want for a specialized optics setup on a far away scouting or interdiction long gun that will seldom need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used to stop the hex screw threads from backing out after they are installed securely in position. An example of these rings are the 30mm style from Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving precision. These types of mounts come in practical for shooting platforms which are transported a lot, to remove the optic from the rifle for protection, or for aiming systems which are employed between several rifles. An example of this mount style is the 30mm mount from Vortex Optics. It typically costs around $250 USD
Details on Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day on the range and your expensive optic by resulting in fogging and creating residue within the scope tube. The majority of scopes protect against moisture from going into the optical tube with a series of sealing O-rings which are water resistant. Generally, these scopes can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample wetness avoidance for standard use rifles for hunting and sporting purposes, unless you plan 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.
Info on Rifle Glass Tube Gas Purging
Another part of avoiding the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the scope is less influenced by temperature level alterations and pressure differences from the outdoor environment which could potentially enable 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.
