What You Need to Know About Glass
Rifle scopes enable you to specifically aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by using a set of lenses inside the scope. The scope’s positioning can be dialed in for consideration of separate natural aspects like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes have about eleven parts which are located within and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other parts. See all eleven parts of optics.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the perfect type of rifle glass is based around what type of shooting you plan to do.
Info on First Focal Plane Glass
First focal plane glass (FFP) come with the reticle in front of the zoom lens. This triggers the reticle to increase in size based upon the extent of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non magnified range. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, far away types of shooting
- Shooting situations where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” plus “lead” relationships for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who prefer a clearer optic picture without area used up by the larger size FFP reticle
Magnification for Rifle Scopes
The quantity of zoom a scope supplies 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 Glass
A single power rifle optic uses a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate since it is fixed.
Info About Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be adjusted between magnification levels. These types of scopes will note the magnification degree in a format like 2-10×32. These numbers indicate the zoom of the scope could be set between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power shift is achieved by applying the power ring component of the scope near the back of the scope by the eye bell piece.
The Power Level and Range of Optics
Here are some recommended scope powers and the distances where they could be efficiently used. Consider that higher power optics will not be as practical as lower powered glass because increased magnification can be a bad thing. The exact same concept goes for longer distances where the shooter needs adequate power to see where to best aim the rifle at the target.
Optic Lens Covering
All present day rifle optic and scope lenses are coated. Lens finishing is a significant aspect of a shooting system when buying high end rifle optics and scope equipment.
HD Versus ED Lenses
Some rifle scope makers even use “HD” or high-definition glass finishings that make the most of various procedures, rare earth compounds, polarizations, and aspects to enhance a wide range of colors and viewable definition through the lens. This high-definition finishing is commonly used with more costly, high density glass which decreases light’s chance to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration may be obvious over things with well defined outlines as light hits the item from certain angles.
Single Covering Versus Multi-Coating
Different optic lenses can even have various finishings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is since the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It must have a finish placed on it so that it will be optimally functional in lots of types of environments, degrees of light (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope makers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This implies the lens has had several treatments applied to them. If a lens gets numerous treatments, it can establish that a manufacturer is taking numerous actions to fight various natural factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also doesn’t necessarily mean the multi-coated lens is much better than a single coated lens. Being “much better” hinges on the producer’s lens treatment solutions and the quality of components used in constructing the rifle glass.
Anti-water Finishing for Rifle Scopes
Water on a scope’s lens does not support retaining a clear sight picture through an optic whatsoever. Lots of top of the line or premium optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Rifle Scope Installation Alternatives
Installing solutions for scopes come in a couple of options. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release variations which use manual levers which allow rifle shooters to quickly install and remove the optics.
Rifle Glass Mounts with Hex Key Rings
Standard, clamp style 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 are created for long range accuracy shooting. This type of scope mount is excellent for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can even be switched out if they all use a similar design mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for optics which are used in between numerous rifles or are situationally focused.
About Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can wreck a day on the range and your expensive optic by triggering fogging and producing residue inside of 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 waterproof. Generally, 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, unless you intend on taking your rifle on a boat and are concerned about the scope still working if it goes overboard and you can still rescue the gun.
Glass Gas Purging
Another element of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the scope is less influenced by temp shifts and pressure distinctions from the outside environment which could potentially allow 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.
