Rifle Glass Details
Rifle scopes enable you to precisely aim a rifle at different targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by utilizing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account numerous environmental considerations like wind speed and elevation to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes have around eleven parts which are found internally and externally on the scope body. These optic pieces consist of the rifle scope’s body, lenses, adjustment turrets, focus rings, and other parts. See all eleven parts of scopes.
About Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has decides where the reticle or crosshair lies in connection with the optic’s magnifying adjustments. It simply means the reticle is behind or in front of the magnifying lens of the scope. Considering the most reliable style of rifle scope is based on what variety of shooting or hunting you intend on undertaking.
First Focal Plane Glass Details
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This induces the reticle to increase in size based on the level of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at 100 yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are very little
- Experienced shooters who know their target “hold over” and also “lead” ratios for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and distances
- Shooters who select a clearer optic picture with less space used up by the bigger FFP reticle
Details on Rifle Optic Zoom
The amount of magnification a scope offers 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 Glass Info
A single power rifle optic uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not adjust because it is a fixed power scope.
About Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification amount in a format like 2-10×32. These numbers indicate the zoom of the scope could be changed in between 2x and 10x power. This also involves the powers in-between 2 and 10. The power shift is achieved using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power and Range Correlation
Here are some recommended scope power levels and the distances where they may be successfully used. Always remember that higher power optics and scopes will not be as effective as lower powered optics due to the fact that increased zoom can be a detractor. The same applies to longer ranges where the shooter needs adequate power to see precisely where to best aim the rifle.
Rifle Scope Lens Coating
All modern-day rifle optic lenses are layered. There are different types and qualities of glass finishings. When thinking about high end rifle optical setups, Lens finishing can be a critical aspect of defining the rifle’s capability. The glass lenses are among the most key parts of the optic considering that they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses safeguards the lens exterior and also improves anti glare capabilities from refracted light and color visibility.
ED Versus HD Rifle Optics
Some scope producers also use “HD” or high-definition lens coatings which use various procedures, chemicals, aspects, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Scope Lens Single Finishing Versus Multi-Coating
Various optic lenses can likewise have different finishes applied to them. All lenses usually have at least some type of treatment or coating used to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while lowering 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 producers similarly make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Anti-water Lens Coatings
Water on a lens does not assist with keeping a clear sight picture through an optic in any way. 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 good example of this kind of treatment. It treats the surface area of the Steiner glass lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Choices for Mounting Glass on Long Guns
Mounting approaches for scopes are available in a few options. There are the basic scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically can be found in quick release variations which use throw levers which permit rifle shooters to quickly mount and dismount the scopes.
Hex Key Rifle Scope Ring Mounts
Standard, 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 designed for long distance precision shooting. This type of scope install is fine for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, several scopes can also be switched in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach tightly 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 the original sighting settings. These types of mounts are useful and beneficial for shooting platforms which are transferred a lot, to take off the optic from the rifle for protection, or for optics which are utilized in between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. Many scopes avoid wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Details on Glass Tube Gas Purging
Another part of avoiding the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the glass is less altered by temp shifts and pressure variations from the outdoor environment which might potentially permit water vapor to seep 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.
