Glass Details
Rifle scopes allow you to specifically aim a rifle at different targets by lining up your eye with the target over a range. They do this through zoom by making use of a set of lenses within the scope. The scope’s alignment can be dialed in to take into account varied ecological elements like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle optics have around 11 parts which are located internally and externally on the scope body. These parts consist of the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other parts. Learn about the eleven parts of scopes.
About Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane an optic has determines where the reticle or crosshair lies in regard to the scopes zoom. It simply suggests the reticle is behind or in front of the magnifying lens of the scope. Choosing the very best style of rifle scope depends on what style of shooting you intend on doing.
Info About First Focal Plane Scopes
First focal plane scopes (FFP) include the reticle ahead of the zoom lens. This induces the reticle to increase in size based upon the level of zoom being used. The result is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are low
- Experienced shooters who recognize their target “hold over” and “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of 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.
- Far away types of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who select a clearer optic sight picture without area taken up by the larger sized FFP reticle
Details on Rifle Glass Magnification
The quantity of zoom a scope supplies is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Scopes
A single power rifle optic will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not adjust considering that it is a set power scope.
Variable Power Lens Optic Facts
Variable power rifle scopes can be changed between magnification power levels. It will note the magnification level in a format like 2-10×32. These numbers mean the zoom of the scope can be set between 2x and 10x power. This also involves the powers in-between 2 and 10. The power adjustment is achieved by applying the power ring component of the scope near the back of the scope by the eye bell piece.
Power and Range Correlations
Here are some suggested scope power levels and the ranges where they may be successfully used. High power scopes will not be as beneficial as lower magnification level glass given that too much magnification can be a negative aspect depending on your shooting distance. The exact same concept applies to longer ranges where the shooter needs to have sufficient power to see where to best aim the rifle.
Lens Finishing for Rifle Scopes
All modern-day rifle scope and optic lenses are layered. There are different types and qualities of coverings. When considering luxury rifle targeting devices, Lens coating can be a critical component of a rifle. The lenses are one of the most significant pieces of the optic since they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens surface area as well as assists with anti glare from refracted sunlight and color exposure.
HD Versus ED Lenses
Some rifle scope companies also use “HD” or high-definition lense finishes which apply various procedures, polarizations, components, and chemicals to enhance separate color ranges and viewable target visibility through lenses. This HD finishing is often used with more costly high density glass which lowers light’s chance to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are represented on the chroma spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration is often visible around objects with hard shapes as light hits the object from certain angles.
Single Covering Versus Multi-Coating
Various optic lenses can also have different coatings applied to them. All lenses generally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic. Due to the fact that the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It must have a finish put on it so that it will be optimally functional in many types of environments, degrees of light (full VS shade), and other shooting conditions.
Single layered 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 decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and the amount you paid for it. Both the make and cost are indications of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Lens Coatings
Water on an optical lens doesn’t improve preserving a clear sight picture through an optic in any way. Numerous top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior surfaces of the Steiner glass lens so the H2O particles can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Glass Installing Options
Installing approaches for scopes come in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use manual levers which permit rifle operators to rapidly mount and remove the glass.
Hex Key Optic Ring Mounting Solutions
Basic, clamp design mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on rifles. These styles of scope mounts use double individual rings to support the scope, and are normally made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope mount is ideal for rifles which are in need of a resilient, rock solid mount which will not change regardless of how much the scope is moved about or abuse the rifle takes. These are the style of mounts you really want to have for a faithful optics setup on a reach out and touch someone hunting or competition firearm that will pretty much never need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to prevent the hex screw threads from backing out after they are installed firmly in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifle platforms which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between several rifles or are situationally focused.
Details on Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. Most scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Rifle Glass Tube Gas Purging
Another element of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the scope is less altered by temperature level alterations and pressure variations from the outside environment which may possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
