Info About Glass
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target at range. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of varied natural considerations like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have around 11 parts which are located within and externally on the optic. These parts consist of the rifle scope’s body, lenses, elevation dials, objective focus rings, and other parts. See all eleven parts of optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Opting for the perfect type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Scope Info
First focal plane glass (FFP) include the reticle ahead of the zoom lens. This triggers the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who know their target “hold over” as well as “lead” relationships for their long gun
- Shooters who do not mind the reticle is bigger and uses up more visual sight room than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots happen within much shorter spaces and ranges
- Shooters who would like a clearer optic sight picture without room used up by the larger size FFP reticle
Rifle Optic Magnification
The amount of zoom a scope provides 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 Power Lens Optics
A single power rifle optic and scope uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not change given that it is a set power scope.
Variable Power Lens Scopes
Variable power rifle scopes use enhanced power. The power change is achieved by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Glass
Here are some suggested scope powers and the ranges where they may be efficiently used. Bear in mind that higher magnification optics will not be as efficient as lower powered scopes due to the fact that increased zoom can be a negative thing in certain situations. The very same idea applies to extended ranges where the shooter needs adequate power to see exactly where to properly aim the rifle at the target.
About Lens Coverings
All modern-day rifle glass lenses are covered. Lens finish can be a vital element of a rifle’s setup when looking into high end rifle optics and scope setups.
HD Versus ED Glass Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishes which use different processes, elements, chemicals, and polarizations to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Info on Single Covering Versus Multi-Coating
Various optic lenses can also have various coverings applied to them. All lenses generally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It must have a finishing put on it so that it will be efficiently functional in many kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope manufacturer and just how much you paid for it. The scope’s maker and cost are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. This suggests the lens has multiple treatments applied to the surfaces. If a lens gets several treatments, it can indicate that a producer is taking numerous actions to combat various environmental elements like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This also does not necessarily imply the multi-coated lens will perform better than a single coated lens. Being “better” depends upon the producer’s lens treatment techniques and the quality of products used in developing the rifle glass.
Anti-water Optic Lens Covering
Water on a scope lens does not assist with maintaining a clear sight picture through a scope in any way. Lots of top of the line and premium scope makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior of the Steiner optic lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Optic Installation Choices
Installing options for scopes are available in a few choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also normally are made in quick release versions which use toss levers which allow rifle operators to rapidly mount and remove the scopes.
Hex Key Rifle Glass Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two different 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 mount is wonderful for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a compatible design mount. These types of mounts are handy for rifles which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between multiple rifles.
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can wreck a day of shooting and your expensive optic by triggering fogging and producing residue within the scope tube. A lot of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant. Typically, these scopes can be submerged under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness avoidance for common use rifles, unless you plan on taking your rifle on your motorboat and are concerned about the optic still working if it falls overboard and you can still recover the firearm.
Gas Purged Rifle Glass Tubes
Another element of preventing the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently taken up by the gas, the optic is less impacted by climate changes and pressure variations from the external environment which may potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
