Glass Facts
Rifle scopes permit you to specifically align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnification by employing a series of lenses within the scope. The scope’s alignment can be adapted to take into account numerous environmental things like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle optics have about eleven parts which are found inside and outside of the scope body. These parts include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of rifle scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane a scope has determines where the reticle or crosshair is located in connection with the optic’s zoom. It actually means the reticle is located behind or in front of the magnification lens of the scope. Looking for the best form of rifle optic depends upon what sort of hunting or shooting you anticipate undertaking.
First Focal Plane Scope Details
First focal plane scopes (FFP) come with the reticle before the magnifying lens. This triggers the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are minor
- Experienced shooters who have an idea for their aim point “hold over” and “lead” relationships for their rifles
- Shooters who do not mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and distances
- Shooters who desire a clearer optic picture with less space used up by the larger sized FFP reticle
Magnification for Rifle Scopes
The quantity of scope magnification you need on your optic depends on the type of shooting you choose to do. Pretty much every type of rifle optic gives some level of zoom. The level of magnification a scope offers is determined by the diameter, thickness, and curvatures of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the glass. This suggests what the shooter is looking at through the scope is magnified times the power aspect of what can normally be seen by human eyes.
Fixed Single Power Lens Rifle Scope Details
A single power rifle scope or optic uses a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate since it is set from the factory.
Info About Adjustable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom level in a format such as 2-10×32. These numbers imply the zoom of the scope can be changed in between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power shift is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range Correlation of Optics
Here are some advised scope powers and the distances where they can be effectively used. Keep in mind that high magnification scopes will not be as effective as lower powered scopes because excessive magnification can be a bad thing. The same applies to longer ranges where the shooter needs increased power to see precisely where to properly aim the rifle at the target.
Optic Lens Finish
All top of the line rifle glass lenses are coated. Lens finish can be a vital aspect of a shooting system when looking at high end rifle optics and scope setups.
Details on Rifle Optic Lens Coatings – HD Versus ED
Some rifle glass manufacturers also use “HD” or high-def lense coatings which apply different processes, chemicals, elements, and polarizations to extract a wide range of color ranges and viewable definition through lenses. This HD finishing is normally used with more costly high density lens glass which decreases light’s potential to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration can be visible over objects with well defined outlines as light hits the item from various angles.
Glass Lens Single Covering Versus Multi-Coating
Different optic lenses can likewise have different finishings used to them. All lenses normally have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
This lens treatment can safeguard 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 coated lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of materials used in developing the rifle scope.
Hydrophobic Glass Lens Covering
Water on a scope lens does not help with maintaining a clear sight picture through an optic whatsoever. Many top of the line or high-end optic producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It provides protection for the exterior of the Steiner scope lens so the H2O particles can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Glass Installation Options
Mounting solutions for scopes come in a few options. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically are made in quick release variations which use manual levers which enable rifle shooters to rapidly install and dismount the optics.
Hex Key Rifle Optic Ring Mounting Solutions
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope install is perfect for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect nicely 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 while keeping accuracy. These types of mounts come in convenient for rifles which are moved around a lot, to remove the optic from the rifle for protection, or for sight systems which are utilized in between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It normally costs around $250 USD
What to Know About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. Most scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic Tubes
Another part of avoiding the accumulation of moisture 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 scope is less altered by temperature alterations and pressure variations from the outdoor environment which may possibly enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
