All About Glass
Rifle scopes enable you to specifically align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s positioning can be dialed in for consideration of varied environmental factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the target. Many modern-day rifle optics have around eleven parts which are arranged within and on the exterior of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials, focus rings, and other parts. See all eleven parts of a scope.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has determines where the reticle or crosshair is located relative to the scopes magnification. It actually implies the reticle is behind or before the magnifying lens of the scope. Considering the most desired type of rifle scope is based on what variety of hunting or shooting you intend on undertaking.
Info About First Focal Plane Glass
First focal plane optics (FFP) include the reticle ahead of the zoom lens. This causes the reticle to increase in size based upon the level of zoom being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non magnified distance. For example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who understand their aim point “hold over” and “lead” relationships for their weapon
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots occur within much shorter ranges and spaces
- Shooters who want a clearer optic sight picture with less area taken up by the larger size FFP reticle
Zoom for Optics
The quantity of magnification a scope provides is identified 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.
Fixed Power Lens Rifle Glass Info
A single power rifle scope and optic uses a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change because it is fixed.
Variable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power change is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Optics
Here are some advised scope power settings and the ranges where they could be efficiently used. High power glass will not be as efficient as lower powered scopes due to the fact that too much zoom can be a bad thing. The same goes for longer distances where the shooter needs enough power to see where to properly aim the rifle at the target.
Details on Scope Lens Finish
All modern rifle scope lenses are layered. There are various types and qualities of glass finishings. When researching high end rifle optical systems, Lens finish can be an essential component of defining the rifle’s capability. The lenses are one of the most significant components 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 protects the lens surface area as well as helps with anti glare capabilities from refracted sunrays and color visibility.
HD Versus ED Glass Lens Coatings
Some scope producers also use “HD” or high-definition lens coverings which use different procedures, aspects, chemicals, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Scope Lens Single Finishing Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses typically have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
Details on Hydrophobic Finish
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.
Scope Mounting Alternatives
Mounting solutions for scopes can be found in a few choices. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also normally are made in quick release variations which use manual levers which permit rifle shooters to rapidly mount and dismount the optics.
Scope Mounting Solutions with Hex Key Rings
Normal, 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 created for long distance precision shooting. This type of scope mount is excellent for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Optic Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. Several scopes can also be swapped out if they all use a similar designed mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving accuracy. These types of mounts are useful and beneficial for rifles which are hauled around 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 type is the 30mm mount designed by the Vortex Optics brand. It normally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by resulting in fogging and developing residue within the scope’s tube. Many optics prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof. Usually, these water-resistant optics can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough humidity prevention for conventional use rifles, unless you anticipate taking your rifle aboard a watercraft and are concerned about the scope still working if it is submerged in water and you can still rescue the firearm.
Gas Purged Rifle Optic Tubes
Another element of preventing the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the scope is less affected by climate shifts and pressure distinctions from the outdoor environment which may possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
