What You Need to Know About Glass
Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target over a distance. They do this through magnification by using a set of lenses inside the scope. The scope’s alignment can be dialed in to account for numerous environmental factors like wind speed and elevation increases 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 through the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle optics have about eleven parts which are found internally and on the exterior of the scope body. These parts consist of the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle glass.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane an optic has decides where the reticle or crosshair is located in relation to the optic’s zoom. It simply suggests the reticle is situated behind or ahead of the magnifying lens of the scope. Picking the most suitable kind of rifle scope depends upon what type of shooting you intend on undertaking.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes 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 distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are low
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” correlations for their long guns
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. This causes the reticle to remain at the exact same overall size in relation to the level of magnification being used. The outcome is that the reticle dimensions evolve based on the zoom chosen to shoot over lengthier distances because the reticle measurements present distinct increments which differ with the magnification level. 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. These styles of optics are handy for:
- Long distance styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who prefer a clearer optic picture with less space used up by the enlarged FFP reticle
Magnification for Rifle Optics
The quantity of magnification a scope supplies is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Scope Info
A single power rifle optic uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust because it is a fixed power scope.
Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification amount in a configuration such as 2-10×32. These numbers suggest the magnification of the scope can be changed in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power adaptation is achieved utilizing the power ring component of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Optics
Here are some suggested scope power levels and the distances where they could be efficiently used. Keep in mind that higher power optics and scopes will not be as practical as lower magnification level glass since increased zoom can be a negative thing in certain situations. The same idea goes for extended ranges where the shooter needs to have sufficient power to see exactly where to properly aim the rifle.
Scope Lens Covering
All contemporary rifle scope and optic lenses are layered. There are different types and qualities of glass lens coatings. Lens covering is an important aspect of a rifle’s setup when looking at high end rifle optics and scope systems. The glass lenses are among the most crucial components of the optic given that they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses shields the lens surface area and also helps with anti glare capabilities from excess natural light and color visibility.
Details on Lens Coatings – HD Versus ED
Some scope manufacturers also use “HD” or high-definition lens coverings which use different processes, chemicals, components, and polarizations to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Optic Lens Finishing Versus Multi-Coating
Various optic lenses can even have various coatings applied to them. All lenses normally have at least some kind of treatment or finishing applied to them before they are used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in numerous types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can protect 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 covered lens depends upon the scope designer and how much money you spent on it. Both are indications of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has multiple treatments applied to the surfaces. If a lens receives numerous treatments, it can establish that a manufacturer is taking multiple actions to combat various natural elements like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This also does not necessarily imply the multi-coated lens will perform better than a single covered lens. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle glass.
Anti-water Finish 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 optic companies will coat their lenses with a hydrophobic or hydrophilic finish which is water repellent.
Options for Installing Optics on Long Guns
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 enable rifle operators to quickly install 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 design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope mount is wonderful for rifles which require a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
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 comparable style mount, multiple scopes can often be swapped out on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining precision. These kinds of mounts come in handy for rifles which are moved a lot, to remove the optic from the rifle for protection, or for sight systems which are employed in between a number of rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Details on Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can mess up a day of shooting and your highly-priced optic by inducing fogging and creating residue inside of the scope tube. The majority of optics prevent humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Usually, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity avoidance for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard watercrafts and are worried about the optic still working if it falls overboard and you can still retrieve the gun.
Gas Purged Scope Tubes
Another part of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the optic is less affected by temperature changes and pressure differences from the outdoor environment which may potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
