Info About Glass
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target over a distance. They do this through zoom by making use of a series of lenses inside the scope. The scope’s alignment can be dialed in to take into account different natural aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will land based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the target. Most contemporary rifle optics have around 11 parts which are found internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, modification dials, focus rings, and other elements. See all eleven parts of a rifle optical system.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane an optic has identifies where the reticle or crosshair lies relative to the optic’s magnifying adjustments. It simply suggests the reticle is behind or before the magnification lens of the optic. Deciding upon the most desired form of rifle scope is based on what variety of hunting or shooting you anticipate doing.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This triggers the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at 100 yards without any “zoom” is still the corresponding tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are minimal
- Experienced shooters who understand their target “hold over” and “lead” ratios for their weapon
- Shooters who do not mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane optics (SFP) include 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.
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who choose a clearer optic picture with less space taken up by the enlarged FFP reticle
Zoom for Rifle Scopes
The measure of scope magnification you require depends upon the style of shooting you plan to do. Just about every type of rifle optic delivers some level of magnification. The volume of magnification a scope supplies is determined by the size, density, and curves of the lenses inside of the rifle optic. The magnifying level of the optic is the “power” of the opic. This denotes what the shooter is aiming at through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Single Power Lens Rifle Scope Info
A single power rifle scope uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change considering that it is a set power scope.
Adjustable Power Lens Rifle Optic Details
Variable power rifle scopes can be tweaked between magnified levels. The power change is performed by the power ring part of the scope near the back of the scope by the eye bell.
Scope Power Level and Ranges
Here are some recommended scope powers and the ranges where they may be efficiently used. Bear in mind that high power optics and scopes will not be as efficient as lower powered optics because too much zoom can be a bad thing. The exact same idea goes for longer distances where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Lens Coating for Scopes
All modern-day rifle optic and scope lenses are coated. Lens finishing can be an important element of a rifle system when buying high end rifle optics and scope setups.
About Glass Lens Coatings – HD Versus ED
Some scope manufacturers likewise use “HD” or high-definition lens coatings which use different procedures, polarizations, components, and chemicals to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Scope Lens Finishing Versus Multi-Coating
Different optic lenses can likewise have different coverings applied to them. All lenses typically have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope developer and how much money you spent on it. Both the make and cost are indications of the lens quality.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Anti-water Covering for Rifle Optics
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic coating which is water repellent.
Rifle Scope Installing Choices
Installing options for scopes can be found in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use throw levers which enable rifle shooters to quickly install and dismount the optics.
Rifle Scope Mounting Solutions with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 distance precision shooting. This type of scope mount is great for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. If they all use a comparable design mount, a number of scopes can often be switched on the range. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top style 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 retaining accuracy. These kinds of mounts are useful and convenient for rifles which are transported a lot, to take off the scope glass from the rifle for protection, or for aiming systems which are adopted in between multiple rifles. An example of this mount style is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by causing fogging and creating residue inside of the scope tube. The majority of scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Glass Tubes
Another part of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less impacted by condition changes and pressure differences from the external environment which might possibly enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
