Glass Details
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target over a distance. They accomplish this through zoom by using a series of lenses inside the scope. The scope’s alignment can be dialed in to take into account different natural elements like wind speed and elevation increases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes and optics have about eleven parts which are located within and outside of the scope body. These parts include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle scopes.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane a scope has decides where the reticle or crosshair is located in regard to the scopes zoom. It actually suggests the reticle is situated behind or before the magnification lens of the scope. Selecting the most effective sort of rifle optic is dependent on what type of shooting or hunting you anticipate undertaking.
First Focal Plane Optics
First focal plane glass (FFP) include the reticle in front of the magnifying lens. This causes the reticle to increase in size based on the extent of zoom being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are small
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” relationships for their firearms
- Shooters who do not mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle to the rear of the magnifying lens. This triggers the reticle to remain at the same scale in relation to the quantity of zoom being used. The final result is that the reticle measurements adapt based on the magnification used to shoot over greater ranges considering that the reticle measurements present distinct increments which can vary with the magnification. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These varieties of glass are handy for:
- Far away kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots take place within much shorter distances and ranges
- Shooters who prefer a clearer optic picture with less area used up by the larger size FFP reticle
Ins and Outs of Rifle Scope Zoom
The quantity of magnification a scope supplies is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Scope Info
A single power rifle scope uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not fluctuate considering that it is a fixed power scope.
Info About Adjustable Power Lens Glass
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will note the magnification degree in a format like 2-10×32. These numbers imply the zoom of the scope can be changed in between 2x and 10x power. This additionally incorporates the powers in-between 2 and 10. The power manipulation is achieved utilizing the power ring component of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power settings and the ranges where they could be successfully used. Highly magnified optics will not be as efficient as lower magnification rifle scope glass considering that too much magnification can be a bad thing. The same idea goes for longer ranges where the shooter needs sufficient power to see where to best aim the rifle at the target.
Rifle Scope Lens Finishing
All modern-day rifle scope lenses are covered in special coatings. There are various types and qualities of glass finishings. Lens finishing can be a crucial element of a rifle when thinking about high-end rifle optics and scope units. The lenses are one of the most important parts of the optic considering that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses protects the lens exterior and assists with anti glare capabilities from excess daylight and color perception.
HD Versus ED Lenses
Some scope manufacturers also use “HD” or high-definition lens coverings which use different processes, aspects, polarizations, and chemicals to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Optic Lens Single Covering Versus Multi-Coating
Various optic lenses can likewise have different finishes used to them. All lenses normally have at least some type of treatment or covering applied to them before they are used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope producer and the amount you spent on it. Both are signs of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” coated. This means the lens has multiple treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can prove that a maker is taking numerous actions to fight different environmental elements like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also does not necessarily mean the multi-coated lens is better than a single covered lens. Being “much better” depends on the producer’s lens treatment technology and the quality of glass used in developing the rifle optic.
Hydrophobic Finish for Glass
Water on a scope’s lens does not assist with maintaining a clear sight picture through an optic whatsoever. Lots of top of the line and premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior of the Steiner optic lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Rifle Scope Installing Alternatives
Installing options for scopes are available in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use throw levers which allow rifle operators to quickly mount and dismount the optics.
Hex Key Scope Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope install 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.
Optic Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. If they all use a similar style mount, a number of scopes can often be swapped out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving accuracy. These kinds of mounts come in handy for rifles which are shipped a lot, to take off the scope glass from the rifle for protection, or for sight systems which are chosen for use between several rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Wetness inside your rifle scope can ruin a day of shooting and your expensive optic by bringing about fogging and developing residue inside of the scope tube. The majority of scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another part of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less influenced by temp shifts and pressure distinctions from the outside environment which could 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.
