What You Need to Know About Glass
Rifle scopes enable you to exactly aim a rifle at different targets by lining up your eye with the target at range. They do this through zoom by making use of a series of lenses inside the scope. The scope’s positioning can be dialed in to account for different ecological factors like wind and elevation increases or decreases to make up 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 using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle scopes and optics have about 11 parts which are located internally and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other parts. See all eleven parts of a rifle optical system.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the optimal type of rifle optic is based around what type of shooting you plan to do.
Info on First Focal Plane Optics
First focal plane glass (FFP) come with the reticle in front of the magnification lens. This induces the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where calculations are marginal
- Experienced shooters who have an idea for their target “hold over” and “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Glass Details
Second focal plane scopes (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 would be 1/5th of the non “zoom” tick reticle measurement.
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots happen within much shorter proximities and ranges
- Shooters who want a clearer optic sight picture without room used up by the larger sized FFP reticle
Details on Optic Zoom
The amount of magnification a scope provides is figured out 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.
Info About Fixed Power Lens Scopes
A single power rifle scope or optic uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate since it is fixed.
Info About Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. It will list the magnification amount in a configuration such as 2-10×32. These numbers indicate the magnification of the scope could be adjusted in between 2x and 10x power. This also incorporates the power levels in-between 2 and 10. The power manipulation is achieved by working with the power ring component of the scope near the back of the scope by the eye bell.
The Power and Range of Rifle Optics
Here are some recommended scope powers and the ranges where they can be effectively used. Highly magnified optics will not be as effective as lower powered scopes since too much magnification can be a bad thing. The same applies to longer ranges where the shooter needs to have increased power to see precisely where to properly aim the rifle at the target.
Info on Lens Coatings
All modern rifle scope and optic lenses are covered in special coatings. There are different types and qualities of lens finishings. When considering high end rifle optics and scope systems, Lens covering can be a significant aspect of defining the rifle’s capability. The glass lenses are one of the most important pieces of the optic due to the fact that they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses offers protection to the lens surface area and helps with anti glare from refracted light and color recognition.
HD Versus ED Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use various techniques, polarizations, chemicals, and elements to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
What to Know About Single Finish Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses normally have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It must have a coating applied to it so that the lens will be efficiently usable in many types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope producer and how much money you spent for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are covered or “multi” covered. This implies the lens has had several treatments applied to the surfaces. If a lens receives multiple treatments, it can show that a company is taking multiple actions to combat various environmental elements like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally doesn’t necessarily imply the multi-coated lens will perform much better than a single covered lens. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in developing the rifle optic.
Anti-water Glass Lens Coating
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Scope Installing Alternatives
Mounting approaches for scopes are available in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use throw levers which permit rifle operators to quickly mount and dismount the glass.
Hex Key Optic Ring Mounts
Basic, clamp type mounting optic rings use hex head screws to position to the flattop style Picatinny scope mount rails on the tops of rifles. These forms of scope mounts use two separate rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This kind of scope mount is exceptional for rifles which need to have a resilient, unfailing mount which will not change despite how much the scope is moved or abuse the rifle takes. These are the type of mounts you really want to have for a devoted optics system on a long distance scouting or sniper competition rifle that will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to stop the hex screw threads from backing out after they are installed securely in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, multiple scopes can also be switched out in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving precision. These types of mounts are useful and handy for rifles which are transferred a lot, to remove the scope glass from the rifle for protection, or for scopes which are utilized in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Info on Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day on the range and your expensive optic by causing fogging and producing residue within the scope tube. The majority of scopes prevent wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Usually, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of humidity prevention for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are concerned about the scope still working if it goes overboard and you can still find the firearm.
Glass Gas Purging
Another part of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less influenced by climate shifts and pressure variations from the outside environment which might potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
