All About Rifle Glass
Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target over a range. They do this through magnifying the target using a series of lenses within the scope. The scope’s alignment can be dialed in to take into account different ecological elements like wind speed and elevation to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes have about 11 parts which are found internally and on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials, focus rings, and other elements. See all eleven parts of a scope.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the perfect type of rifle glass is based on what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are marginal
- Experienced shooters who recognize their target “hold over” as well as “lead” equations for their long guns
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind the zoom 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.
- Long distance kinds of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who select a clearer optic sight picture with less area used up by the enlarged FFP reticle
About Glass Magnification
The quantity of scope magnification you need on your scope depends upon the form of shooting you desire to do. Practically every type of rifle scope delivers some amount of magnification. The level of magnification a scope delivers is determined by the dimension, thickness, and curvatures of the lens glass inside of the rifle scope. The magnification of the optic is the “power” of the glass. This denotes what the shooter is looking at through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Single Power Lens Scopes
A single power rifle scope and optic will have a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is set from the factory.
About Adjustable Power Lens Rifle Optics
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 Correlations
Here are some recommended scope power settings and the ranges where they could be efficiently used. Keep in mind that higher magnification glass will not be as efficient as lower magnification level optics because increased magnification can be a negative thing in certain situations. The exact same concept applies to longer distances where the shooter needs sufficient power to see where to best aim the rifle at the target.
Details on Rifle Scope Lens Finish
All modern rifle optic lenses are covered. Lens finish can be a significant element of a shooting system when purchasing high end rifle optics and scope setups.
HD Versus ED Lenses
Some rifle scope makers will also use “HD” or high-def glass finishings which apply various processes, polarizations, chemicals, and elements to enhance separate colors and viewable target visibility through lenses. This HD finish is often used with more costly high density glass which drops light’s opportunity to refract by means of the lens glass. Some scope suppliers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be visible around objects with hard shapes as light hits the object from specific angles.
Rifle Optic Lens Single Finish Versus Multi-Coating
Different scope lenses can even have different finishings applied to them. All lenses normally have at least some kind of treatment or coating applied to them before they are 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 finely tuned optic. It must have a covering put on it so that it will be efficiently functional in many kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope developer and how much you spent for it. Both the manufacturer and amount are indications of the lens quality.
Some scope makers likewise make it a point to define if their optic lenses are covered or “multi” covered. This indicates the lens has had numerous treatments applied to the surfaces. If a lens gets multiple treatments, it can establish that a company is taking several steps to fight different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This also doesn’t necessarily imply the multi-coated lens is better than a single coated lens. Being “better” hinges on the maker’s lens treatment technology and the quality of products used in creating the rifle glass.
Scope Lens Hydrophobic Finishing
Water on a scope’s lens does not assist with retaining a clear sight picture through a scope whatsoever. Lots of top of the line and high-end scope producers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this kind 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 outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Rifle Scope Installation Choices
Installing options for scopes come in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally come in quick release variations which use throw levers which allow rifle shooters to quickly mount and remove the glass.
Hex Key Scope Ring Mounting Solutions
Basic, clamp design mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These types of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This form of scope mount is good for rifles which are in need of a durable, unfailing mount which will not shift no matter how much the scope is moved or jarring the rifle takes. These are the design of mounts you should get for a faithful optics setup on a far away hunting or competition long gun that will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to keep the hex screws from wiggling out after they are installed securely in position. An example of these rings are the 30mm type made by the Vortex Optics company. The set usually costs around $200 USD
Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. If they all use a similar design mount, several scopes can also be swapped on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining accuracy. These types of mounts are useful and practical for rifles which are carried a lot, to take off the scope glass from the rifle for protection, or for sight systems which are used in between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Details on Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes avoid moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another part of preventing the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the optic is less affected by condition shifts and pressure distinctions from the outdoor environment which might potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
