What You Need to Know About Glass
Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target at range. They do this through zoom by making use of a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account separate environmental things like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have around 11 parts which are located internally and on the exterior of the scope body. These parts consist of the rifle scope’s body, lenses, elevation dials, objective focus rings, and other components. Learn about the eleven parts of rifle optics.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has identifies where the reticle or crosshair is located relative to the scopes magnifying adjustments. It actually means the reticle is behind or ahead of the magnification lens of the optic. Deciding on the best kind of rifle scope is dependent on what form of shooting or hunting you plan on undertaking.
First Focal Plane Optic Facts
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who know their target “hold over” and also “lead” relationships for their firearms
- Shooters who do not mind the reticle is bigger and uses up more visual sight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane scopes (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots occur within shorter ranges and spaces
- Shooters who want a clearer optic sight picture without room used up by the bigger FFP reticle
Zoom for Rifle Optics
The amount of zoom a scope supplies is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Glass
A single power rifle scope or optic comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not change because it is a fixed power optic.
Variable Power Lens Scope Info
Variable power rifle scopes can be modified between magnified levels. The power modification is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power settings and the ranges where they may be efficiently used. Remember that high magnification optics and scopes will not be as efficient as lower powered scopes due to the fact that too much zoom can be a bad thing. The same relates to longer ranges where the shooter needs to have adequate power to see where to properly aim the rifle.
About Lens Coverings
All modern rifle optic lenses are coated. There are different types and qualities of finishings. When shopping for high end rifle optics and scope devices, Lens coating can be a vital element of a rifle. The lenses are one of the most significant components of the scope considering that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses shields the lens surface as well as assists with anti glare capabilities from refracted light and color visibility.
Details on Glass Lens Coatings – HD Versus ED
Some optic producers will also use “HD” or high-def glass coatings which employ different processes, polarizations, components, and chemicals to draw out different colors and viewable target definition through the lens. This high-def coating is commonly used with more costly high density glass which decreases light’s potential to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration may be visible around items with hard outlines as light hits the item from certain angles.
Single Finish Versus Multi-Coating for Glass
Different scope lenses can also have various finishes applied to them. All lenses normally 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 is part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in numerous types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less advantageous 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 makers similarly make it a point to specify if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Scope Lens Anti-water Finish
Water on an optic’s lens doesn’t assist with retaining a clear sight picture through an optic whatsoever. Lots of top of the line or premium scope manufacturers 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 area of the Steiner optic lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Options for Installing Rifle Scopes on Long Guns
Mounting approaches for scopes come in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also generally come in quick release versions which use throw levers which allow rifle shooters to quickly install and remove the scope.
Optic Mounts 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 two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long distance precision shooting. This type of scope install is excellent for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Optic Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can also be swapped out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect solidly 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 back on the rifle while maintaining precision. These kinds of mounts are useful and convenient for shooting platforms which are transferred between vehicles a lot, to take off the scope from the rifle for protection, or for aiming systems which are chosen for use between a number of rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. The majority of scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are water resistant.
Info on Rifle Glass Tube Gas Purging
Another component of avoiding the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the scope is less affected by temperature shifts and pressure differences from the outside environment which could possibly enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
