What You Need to Know About Glass
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target over a range. They do this through zoom by employing a series of lenses within the scope. The scope’s positioning can be adjusted for the consideration of different environmental things like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle scopes have about eleven parts which are found internally and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, windage turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle optics.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has identifies where the reticle or crosshair is located in regard to the scopes magnification. It actually means the reticle is situated behind or before the magnifying lens of the optic. Picking the most desired kind of rifle optic is based upon what type of shooting or hunting you anticipate undertaking.
First Focal Plane Optic Facts
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. For instance, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the corresponding tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are very little
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” relationships for their weapon
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane scopes (SFP) include the reticle behind the magnification lens. This induces the reticle to stay at the very same overall size in connection with the amount of zoom being used. The effect is that the reticle dimensions shift based upon the zoom chosen to shoot over lengthier distances since the reticle markings represent different increments which can vary with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick. These particular styles of optics work for:
- Far away kinds of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots happen within shorter distances and ranges
- Shooters who select a clearer optic sight picture with less area used up by the enlarged FFP reticle
The quantity of scope magnification you need on your optic depends upon the style of shooting you intend to do. Practically every kind of rifle optic offers some degree of zoom. The volume of zoom a scope supplies is identified by the diameter, thickness, and curves of the lens glass inside of the rifle scope. The zoom of the scope is the “power” of the scope. This implies what the shooter is looking at through the scope is magnified times the power factor of what can usually be seen by human eyes.
Info on Single Power Lens Scopes
A single power rifle scope will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust since it is a fixed power scope.
Variable Power Lens Rifle Glass
Variable power rifle scopes can be modified between magnified levels. The power adjustment is handled using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope power settings and the ranges where they may be successfully used. Consider that high power scopes and optics will not be as effective as lower magnification level scopes since increased magnification can be a bad thing. The same concept relates to extended ranges where the shooter needs sufficient power to see precisely where to properly aim the rifle at the target.
Glass Lens Finish
All modern-day rifle scope and optic lenses are covered in special coatings. There are different types and qualities of glass lens coatings. Lens finishing is an essential aspect of a rifle’s setup when looking at high-end rifle optics and scope equipment. The lenses are among the most vital pieces of the glass as they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses protects the lens surface area as well as helps with anti glare capabilities from excess daylight and color exposure.
Details on Scope Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens coatings which use various techniques, polarizations, chemicals, and components to draw out a wide range of colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Various 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 prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering 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 maker and how much money you paid for it. Both the make and cost are signs of the lens quality.
Some scope manufacturers likewise make it a point to define if their optic lenses are layered or “multi” covered. This implies the lens has had several treatments applied to the surfaces. If a lens gets multiple treatments, it can establish that a company is taking numerous steps to combat different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally doesn’t necessarily mean the multi-coated lens is much better than a single covered lens. Being “much better” is dependent on the maker’s lens treatment innovation and the quality of components used in constructing the rifle scope.
Anti-water Coating for Rifle Glass
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic anti-water finishing.
Rifle Glass Installing Choices
Mounting options for scopes come in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also generally can be found in quick release versions which use toss levers which allow rifle shooters to rapidly mount and dismount the scopes.
Glass Mounting Solutions with Hex Key Rings
Standard, clamp-on type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use a pair of detached rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are created for long distance accuracy shooting. This kind of scope mount is excellent for rifle systems which need a resilient, rock solid mount which will not shift regardless of just how much the scope is moved or jarring the rifle takes. These are the design of mounts you really want to have for a devoted optics system on a long distance scouting or sniper competition long gun that will pretty much never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to keep the hex screw threads from backing out after they are mounted safely in place. An example of these mounting rings are the 30mm style from the Vortex Optics company. The set usually costs around $200 USD
Rifle Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, multiple scopes can also be swapped out. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving precision. These types of mounts come in beneficial for rifles which are hauled around a lot, to remove the glass from the rifle for protection, or for scopes which are used in between numerous rifles. An example of this mount type is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Scope Tubes
Another element of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the scope is less impacted by temp shifts and pressure variations from the external environment which could possibly permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
