Information About Glass
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through zoom by employing a set of lenses within the scope. The scope’s alignment can be adapted for consideration of different ecological aspects like wind speed and elevation to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern rifle optics have around 11 parts which are located within and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of scopes.
About Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the perfect type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Scopes
First focal plane scopes (FFP) come with the reticle before the zoom lens. This induces the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minor
- Experienced shooters who recognize their aim point “hold over” and also “lead” relationships for their long guns
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.
- Long distance kinds of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots happen within shorter distances and ranges
- Shooters who would like a clearer optic picture with less area used up by the larger size FFP reticle
Ins and Outs of Rifle Glass Zoom
The quantity of magnification a scope provides is identified by the diameter, 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 Rifle Optics
A single power rifle optic uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not fluctuate considering that it is fixed.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power adjustment is performed by using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope power levels and the ranges where they can be successfully used. Highly magnified rifle scope glass will not be as useful as lower powered rifle scope glass considering that too much magnification can be a negative aspect depending on your shooting distance. The same concept goes for longer distances where the shooter needs sufficient power to see exactly where to properly aim the rifle.
Lens Finishing for Rifle Glass
All modern-day rifle optic lenses are layered. There are different types and qualities of lens finishings. When researching high end rifle targeting devices, Lens covering can be a significant component of defining the rifle’s capability. The glass lenses are one of the most critical parts of the optic because they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses shields the lens surface and helps with anti glare capabilities from excess light and color exposure.
HD Versus ED Lens Coatings
Some scope companies even use “HD” or high-def lense coatings which take advantage of different processes, chemicals, components, and polarizations to extract various colors and viewable target definition through the lens. This HD finishing is commonly used with more costly, high density glass which reduces light’s capability to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often visible around items with defined shapes as light hits the item from certain angles.
Single Rifle Scope Lens Finishing Versus Multi-Coating
Different scope lenses can also have different coverings applied to them. All lenses usually have at least some type 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 becomes part of the finely tuned optic. It must have a covering placed on it so that the lens will be efficiently usable in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while lowering 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 maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” covered. This implies the lens has several treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can indicate that a company is taking numerous actions to fight various environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also does not necessarily suggest the multi-coated lens is much better than a single layered lens. Being “better” depends on the producer’s lens treatment techniques and the quality of materials used in building the rifle optic.
About Anti-water Coating
Water on a scope lens doesn’t improve keeping a clear sight picture through a scope whatsoever. Many top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the exterior surfaces of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Choices for Installing Rifle Optics on Firearms
Mounting solutions for scopes come in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release versions which use throw levers which allow rifle shooters to quickly install and remove the optics.
Hex Key Glass Ring Mounting Solutions
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope install is excellent for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, multiple scopes can often be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving precision. These kinds of mounts come in handy for rifles which are moved a lot, to take off the scope glass from the rifle for protection, or for scopes which are adopted between numerous rifles. An example of this mount style is the 30mm mount from the Vortex Optics brand. It generally costs around $250 USD
About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can wreck a day on the range and your highly-priced optic by resulting in fogging and producing residue within the scope’s tube. A lot of optics prevent wetness from getting in the scope tube with a series of sealing O-rings which are water resistant. Generally, these scopes can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are concerned about the optic still performing if it goes over the side and you can still recover the gun.
Details on Rifle Glass Tube Gas Purging
Another part of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the glass is less affected by temperature level shifts and pressure distinctions from the outdoor environment which might potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
