Glass Details
Rifle scopes permit you to specifically align a rifle at different targets by aligning your eye with the target over a range. They do this through magnification by employing a series of lenses within the scope. The scope’s alignment can be adapted to take into account separate natural aspects like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle optics have about 11 parts which are arranged internally and outside of the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other components. Learn about the eleven parts of rifle optics.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle glass depends on what type of shooting you plan on doing.
First Focal Plane Scopes
First focal plane glass (FFP) come with the reticle ahead of the magnifying lens. This triggers the reticle to increase in size based on the level of magnification being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. For instance, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the corresponding tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” correlations for their firearms
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots take place within much shorter spaces and ranges
- Shooters who like a clearer optic picture with less area taken up by the bigger FFP reticle
Rifle Optic Zoom
The amount of magnification a scope supplies is determined 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.
Fixed Power Lens Rifle Optic Info
A single power rifle optic comes with a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change because it is set from the factory.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom degree in a format such as 2-10×32. These numbers suggest the magnification of the scope could be adjusted between 2x and 10x power. This always involves the powers in-between 2 and 10. The power manipulation is accomplished utilizing the power ring component of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Optics
Here are some recommended scope power settings and the ranges where they could be efficiently used. Remember that high magnification scopes and optics will not be as practical as lower powered optics and scopes because excessive magnification can be a negative thing in certain situations. The same idea relates to extended ranges where the shooter needs to have adequate power to see precisely where to best aim the rifle at the target.
Lens Coating for Rifle Optics
All contemporary rifle glass lenses are covered. Lens finishing is a crucial element of a rifle’s setup when considering high end rifle optics and scope systems.
Info on Glass Lens Coatings – HD Versus ED
Some rifle scope companies even use “HD” or high-definition lense finishes which employ various processes, aspects, polarizations, and chemical applications to extract various color ranges and viewable target definition through the lens. This HD covering is normally used with increased density lens glass which reduces light’s ability to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” indicating 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 may be noticeable around objects with defined outlines as light hits the item from certain angles.
Single Coating Versus Multi-Coating
Various scope lenses can also have various finishings applied to them. All lenses usually have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that 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 it will be efficiently functional in numerous kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can shield the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope company and how much you spent paying for it. Both the manufacturer and amount are signs of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
About Hydrophobic Finish
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Many top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Optic Installing Choices
Installing solutions for scopes come in a couple of options. There are the basic scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release versions which use toss levers which enable rifle shooters to rapidly install and remove the glass.
Hex Key Rifle Scope Ring Mounts
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount 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 are created for long distance accuracy shooting. This type of scope install is fine for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle. If they all use a similar style mount, a number of scopes can often be swapped in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining accuracy. These types of mounts are useful and handy for rifles which are transferred between vehicles a lot, to remove the scope from the rifle for protection, or for optics which are utilized in between a number of rifles. An example of this mount style is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by causing fogging and producing residue inside of the scope tube. Most scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Info Around Optic Tube Gas Purging
Another part of avoiding the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the optic is less impacted by temperature changes and pressure distinctions from the outside environment which might potentially enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
