Info Glass
Rifle scopes allow you to precisely aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by employing a set of lenses within the scope. The scope’s positioning can be dialed in for the consideration of separate environmental things like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle optics have about 11 parts which are arranged internally and externally on the scope body. These scope parts include the rifle scope’s body, lenses, windage turrets, objective focus rings, and other elements. Learn about the eleven parts of glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has identifies where the reticle or crosshair lies in relation to the scopes magnifying adjustments. It literally means the reticle is situated behind or in front of the magnifying lens of the optic. Deciding on the most reliable kind of rifle scope is based upon what form of hunting or shooting you intend on undertaking.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are low
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” ratios for their firearms
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind the magnifying lens. This triggers the reticle to remain at the exact same dimensions relative to the amount of zoom being used. The outcome is that the reticle measurements alter based upon the magnification chosen to shoot over greater distances given that the markings present distinct increments which can vary with the zoom level. 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. These sorts of scopes work for:
- Long distance kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who desire a clearer optic picture without space taken up by the bigger FFP reticle
About Rifle Optic Zoom
The amount of zoom a scope supplies is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
About Fixed Single Power Lens Glass
A single power rifle optic will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not fluctuate since it is a set power scope.
Adjustable Power Lens Optics
Variable power rifle scopes use enhanced power. The power modification is handled by the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Glass
Here are some suggested scope powers and the ranges where they can be efficiently used. Always remember that high power optics will not be as effective as lower powered scope and optics because increased magnification can be a negative thing in certain situations. The exact same concept goes for longer distances where the shooter needs adequate power to see where to properly aim the rifle.
Scope Lens Coating
All contemporary rifle optic lenses are covered in special coatings. There are various types and qualities of glass coatings. When considering high end rifle optical systems, Lens finishing can be a very important aspect of defining the rifle’s capability. The glass lenses are among the most key pieces of the scope considering that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses offers protection to the lens exterior and even assists with anti glare capabilities from refracted sunshine and color perception.
ED Versus HD Scopes
Some scope producers will also use “HD” or high-definition lense coverings which use various processes, rare earth compounds, polarizations, and elements to draw out different color ranges and viewable target visibility through lenses. This high-def coating is frequently used with more costly high density lens glass which reduces light’s opportunity to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable over items with hard outlines as light hits the item from particular angles.
Single Coating Versus Multi-Coating
Different scope lenses can also have different finishings applied to them. All lenses usually have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a covering placed on it so that the lens will be optimally usable in lots of kinds of environments, degrees of light (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope maker and the amount you paid for it. The scope’s maker and cost are signs 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 producer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Lens Finishes
Water on an optical lens does not improve retaining a clear sight picture through an optic at all. Numerous top of the line and premium scope producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the surface of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Optic Installation Choices
Installing approaches for scopes are available in a few options. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release variations which use manual levers which enable rifle shooters to quickly mount and remove the glass.
Glass Mounts with Hex Key Rings
Standard, clamp design 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 two different rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope install is great for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a similar design mount, several scopes can often be swapped out on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping precision. These kinds of mounts are useful and practical for shooting platforms which are moved a lot, to take off the scope glass 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 designed by Vortex Optics. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle optic can wreck a day of shooting and your highly-priced optic by causing fogging and creating residue inside of the scope tube. Many optics prevent wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Normally, these optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample humidity prevention for conventional use rifles, unless you intend on taking your rifle on a boat and are concerned about the scope still performing if it falls overboard and you can still recover the firearm.
Glass Gas Purging
Another element of preventing the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the glass is less influenced by climate changes and pressure variations from the external environment which could potentially allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
