Info About Glass
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by using a series of lenses inside the scope. The scope’s positioning can be adjusted to take into account varied natural considerations like wind and elevation decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle optics have around 11 parts which are found within and externally on the scope body. These parts consist of the rifle scope’s body, lenses, modification dials, focus rings, and other elements. Learn about the eleven parts of rifle optics.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the perfect type of rifle glass depends on what type of shooting you plan on doing.
First Focal Plane Scope Facts
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This induces the reticle to increase in size based upon 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 range. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the same tick at one hundred yards using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who have an idea for their target “hold over” and also “lead” correlations for their rifles
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight room than a SFP reticle
Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle to the rear of the magnifying lens. This causes the reticle to stay at the same overall size in connection with the level of zoom being used. The end result is that the reticle measurements adapt based on the magnification used to shoot over lengthier ranges given that the markings present different increments which change with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These sorts of optics work for:
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots happen within much shorter spaces and ranges
- Shooters who choose a clearer optic picture with less space taken up by the larger size FFP reticle
Zoom for Rifle Optics
The quantity of scope zoom you need on your glass is based on the style of shooting you choose to do. Practically every type of rifle optic gives some degree of zoom. The volume of magnification a scope provides is determined by the diameter, density, and curvatures of the lenses inside of the rifle optic. The magnification of the optic is the “power” of the scope. This implies what the shooter is checking out through the scope is magnified times the power element of what can normally be seen by human eyes.
Fixed Power Lens Rifle Glass
A single power rifle scope and optic uses a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not change given that it is a set power scope.
Info About Variable Power Lens Rifle Scopes
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will list the zoom amount in a format like 2-10×32. These numbers mean the magnification of the scope can be adjusted in between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power modification is accomplished by applying the power ring part of the scope near the rear of the scope by the eye bell piece.
Power and Range
Here are some suggested scope power settings and the distances where they may be effectively used. Always remember that high magnification optics will not be as practical as lower powered scopes since excessive magnification can be a detractor. The same idea applies to extended distances where the shooter needs to have enough power to see precisely where to best aim the rifle at the target.
About Lens Coverings
All contemporary rifle optic lenses are coated. There are various types and qualities of glass lens coverings. When considering luxury rifle optics and scope setups, Lens finishing can be a very important component of a rifle. The lenses are one of the most significant pieces of the optic considering that they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses offers protection to the lens surface and also improves anti glare capabilities from excess daylight and color perception.
HD Versus ED Rifle Optic Lens Coatings
Some scope makers also use “HD” or high-definition lens coatings which use different methods, components, chemicals, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Optic Lens Finishing Versus Multi-Coating
Various optic lenses can even have different coverings applied to them. All lenses generally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It must have a coating put on it so that the lens will be optimally usable in numerous types of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” coated. This suggests the lens has had several treatments applied to them. If a lens receives multiple treatments, it can show that a company is taking numerous actions to fight different natural factors like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally does not always indicate the multi-coated lens will perform better than a single covered lens. Being “better” depends upon the producer’s lens treatment innovation and the quality of products used in developing the rifle optic.
Anti-water Lens Coatings
Water on an optical lens does not improve retaining a clear sight picture through a scope at all. Many top of the line and premium scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the exterior surfaces of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Glass Mounting Options
Installing solutions for scopes are available in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various types of mounts also typically come in quick release variations which use toss levers which allow rifle shooters to quickly mount and remove the optics.
Hex Key Scope Ring Mounts
Normal, clamp style 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range accuracy shooting. This type of scope install is fine for rifles which require a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a similar style mount. These types of mounts come in handy for long guns which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles.
About Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can destroy a day on the range and your highly-priced optic by causing fogging and creating residue within the scope’s tube. Most optics protect against wetness from getting in the optical tube with a system of sealing O-rings which are waterproof. Typically, these water resistant optics can be immersed underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture content avoidance for basic use rifles for hunting and sporting purposes, unless you plan on taking your rifle on a boat and are concerned about the scope still working if it is submerged in water and you can still recover the firearm.
What to Know About Scope Tube Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the glass is less altered by condition changes and pressure differences from the outdoor environment which may possibly permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
