Glass Information
Rifle scopes allow you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through zoom by utilizing a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account different ecological things like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to understand exactly 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 target. Most modern rifle optics have about 11 parts which are found internally and externally on the scope body. These parts consist of the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other components. Learn about the eleven parts of rifle glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the best type of rifle scope depends on what type of shooting you plan on doing.
First Focal Plane Optic Info
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where estimations are minor
- Experienced shooters who know their aim point “hold over” and also “lead” ratios for their firearms
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle to the rear of the magnifying lens. This causes the reticle to stay at the very same overall size relative to the volume of zoom being used. The result is that the reticle dimensions shift based upon the magnification used to shoot over greater distances due to the fact that the reticle measurements represent various increments which fluctuate with the zoom. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These sorts of glass work for:
- Far away kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and distances
- Shooters who desire a clearer optic picture without space taken up by the enlarged FFP reticle
Ins and Outs of Optic Magnification
The measure of scope magnification you need on your scope depends upon the type of shooting you choose to do. Virtually every kind of rifle scope provides some amount of magnification. The level of zoom a scope provides is determined by the diameter, thickness, and curves of the lens glass inside of the rifle scope. The magnifying level of the scope is the “power” of the opic. This means what the shooter is observing through the scope is magnified times the power factor of what can typically be seen by human eyes.
Fixed Power Lens Scopes
A single power rifle scope will have a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate considering that it is a fixed power scope.
Info on Adjustable Power Lens Optics
Variable power rifle scopes can be changed between magnification power levels. These types of scopes will list the magnification level in a format such as 2-10×32. These numbers imply the magnification of the scope can be set in between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power adaptation is achieved by making use of the power ring component of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some recommended scope powers and the ranges where they can be effectively used. Highly magnified rifle scope glass will not be as beneficial as lower magnification rifle scope glass since too much zoom can be a bad thing. The exact same concept goes for longer ranges where the shooter needs enough power to see where to best aim the rifle at the target.
Rifle Scope Lens Coating
All modern-day rifle glass lenses are covered. Lens finishing can be a crucial aspect of a shooting platform when purchasing high end rifle optics and scope systems.
HD Versus ED Rifle Glass Lens Coatings
Some rifle scope producers also use “HD” or high-def glass finishings which make the most of different processes, aspects, polarizations, and chemicals to enhance numerous colors and viewable definition through the lens. This HD finish is typically used with greater density lens glass which brings down light’s potential to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious around things with defined outlines as light hits the item from certain angles.
Single Glass Lens Finishing Versus Multi-Coating
Different scope lenses can also have different coverings applied to them. All lenses typically have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It needs to have a finishing placed on it so that it will be efficiently functional in numerous kinds of environments, degrees of sunlight (full VS shade), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope manufacturer and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This implies the lens has had several treatments applied to the surfaces. If a lens gets several treatments, it can show that a manufacturer is taking multiple actions to combat different environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This also does not always imply the multi-coated lens is better than a single coated lens. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in constructing the rifle optic.
Anti-water Rifle Scope Lens Finishing
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic anti-water covering.
Options for Mounting Optics on Firearms
Installing options for scopes come in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also typically can be found in quick release versions which use throw levers which enable rifle operators to quickly install and dismount the optics.
Hex Key Optic Ring Mounts
Standard, clamp-on design mounting scope rings use hex head screws to position to the flattop design Picatinny scope mounting rails on rifles. These kinds of scope mounts use double separate rings to support the scope, and are normally made from 7075 T6 billet aluminum which are created for far away accuracy shooting. This kind of scope mount is effective for rifle systems which require a durable, unfailing mount which will not change no matter how much the scope is moved about or jarring the rifle takes. These are the design of mounts you should get for a faithful scope system on a far away scouting or tournament long gun which will pretty much never need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to stop the hex screws from wiggling out after they are mounted firmly in place. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set generally costs around $200 USD
Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a comparable style mount, multiple scopes can often be switched out in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining precision. These kinds of mounts are useful and practical for shooting platforms which are transported a lot, to take off the scope from the rifle for protection, or for aiming systems which are employed in between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can mess up a day of shooting and your highly-priced optic by resulting in fogging and making residue within the scope’s tube. The majority of optics protect against wetness from entering the optical tube with a series of sealing O-rings which are water resistant. Typically, these water resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture prevention for conventional use rifles, unless you anticipate taking your rifle on a boat and are worried about the scope still performing if it goes over the side and you can still salvage the firearm.
Gas Purged Optic Tubes
Another element of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the glass is less affected by temperature changes and pressure distinctions from the outside environment which may possibly 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.
