Information Rifle Glass
Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target at range. They do this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be adjusted for consideration of various natural things like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern rifle optics have around eleven parts which are found internally and on the exterior of the scope. These scope parts include the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other elements. See all eleven parts of a rifle scope.
About Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane an optic has decides where the reticle or crosshair lies in connection with the optic’s magnification. It literally means the reticle is located behind or in front of the magnifying lens of the scope. Considering the most reliable type of rifle glass is dependent on what form of hunting or shooting you plan on doing.
First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who recognize their aim point “hold over” and “lead” relationships for their rifles
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight room 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” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance styles of shooting where shooters have additional time to make ballistic computations
- 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 enlarged FFP reticle
Magnification for Rifle Scopes
The amount of magnification a scope provides is figured out 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 Glass
A single power rifle scope or optic uses a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of scope can not adjust since it is a set power scope.
Info About Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will list the magnification level in a configuration such as 2-10×32. These numbers suggest the zoom of the scope could be set in between 2x and 10x power. This also incorporates the power levels in-between 2 and 10. The power modification is accomplished by employing the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power Level and Range of Rifle Glass
Here are some suggested scope powers and the distances where they can be efficiently used. Remember that higher magnification optics and scopes will not be as practical as lower powered scope and optics because excessive magnification can be a bad thing. The same concept relates to extended distances where the shooter needs enough power to see precisely where to properly aim the rifle.
Lens Covering for Rifle Scopes
All cutting-edge rifle scope and optic lenses are layered. Lens finishing is an essential aspect of a rifle when considering high end rifle optics and scope equipment.
Info on Lens Coatings – HD Versus ED
Some scope producers likewise use “HD” or high-definition lens coverings which use different procedures, aspects, polarizations, and chemicals to draw out different colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating for Glass
Various scope lenses can even have different coatings applied to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope makers also 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 building the rifle scope.
Hydrophobic Lens Coatings
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic finishing which is water repellent.
Choices for Mounting Glass on Long Guns
Mounting approaches for scopes can be found in a couple of choices. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually come in quick release versions which use manual levers which enable rifle operators to quickly mount and dismount the optics.
Glass Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style 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 are developed for long range accuracy shooting. This type of scope install is fine for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. If they all use a comparable style mount, multiple scopes can often be swapped out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping accuracy. These types of mounts come in convenient for rifles which are moved around a lot, to take off the glass from the rifle for protection, or for sight systems which are adopted in between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle glass can mess up a day on the range and your costly optic by inducing fogging and creating residue inside of the scope tube. Most scopes prevent moisture from going into the scope tube with a series of sealing O-rings which are water resistant. Usually, these water resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content avoidance for basic use rifles, unless you anticipate taking your rifle sailing and are concerned about the optic still working if it goes overboard and you can still find the gun.
Glass Gas Purging
Another part of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the scope is less affected by temperature level alterations and pressure differences from the outside environment which may possibly enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
