What You Need to Know About Rifle Glass
Rifle scopes enable you to exactly aim a rifle at different targets by aligning your eye with the target over a distance. They do this through magnification by making use of a set of lenses within the scope. The scope’s positioning can be adjusted to account for numerous natural factors like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended target. A lot of modern rifle optics have around eleven parts which are found inside and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. Learn about the eleven parts of glass.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane a scope has establishes where the reticle or crosshair lies relative to the optic’s zoom. It simply means the reticle is situated behind or ahead of the magnification lens of the optic. Deciding on the most beneficial style of rifle optic is based upon what sort of shooting or hunting you intend on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This induces the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the very same tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are low
- Experienced shooters who know their target “hold over” and “lead” equations for their firearms
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane scopes (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who desire a clearer optic picture without room taken up by the larger size FFP reticle
Glass Zoom
The quantity of magnification a scope supplies is figured out 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 Single Power Lens Optic Facts
A single power rifle scope or optic uses a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust since it is set from the factory.
About Variable Power Lens Glass
Variable power rifle scopes have adjustable power. It will list the zoom level in a configuration like 2-10×32. These numbers suggest the magnification of the scope could be set in between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power shift is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell.
Rifle Glass Power and Ranges
Here are some advised scope powers and the distances where they may be efficiently used. Highly magnified optics will not be as effective as lower magnification level glass given that too much zoom can be a bad thing. The very same idea goes for longer ranges where the shooter needs adequate power to see where to best aim the rifle at the target.
Lens Finish for Optics
All modern rifle scope lenses are covered in special coatings. There are various types and qualities of glass lens coverings. When researching luxury rifle optics and scope systems, Lens finishing can be a vital element of a rifle. The lenses are one of the most critical components of the scope because they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses offers protection to the lens exterior and even helps with anti glare capabilities from excess sunrays and color exposure.
HD Versus ED Rifle Glass Lens Coatings
Some rifle glass companies additionally use “HD” or high-def glass coatings that make the most of different procedures, polarizations, chemicals, and components to extract numerous color ranges and viewable definition through lenses. This high-definition finish is typically used with increased density lens glass which brings down light’s potential to refract by means of the lens glass. Some scope manufacturers use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often visible around objects with hard outlines as light hits the object from particular angles.
Single Glass Lens Covering Versus Multi-Coating
Various optic lenses can even have various coverings applied to them. All lenses usually have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in many kinds of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less useful 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 producers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This means the lens has had multiple treatments applied to them. If a lens receives numerous treatments, it can prove that a maker is taking several actions to fight various environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also doesn’t necessarily suggest the multi-coated lens is much better than a single covered lens. Being “better” hinges on the producer’s lens treatment solutions and the quality of materials used in building the rifle optic.
Anti-water Finishing for Glass
Water on an optic’s lens does not improve maintaining a clear sight picture through a scope at all. Many 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 kind of treatment. It provides protection for the surface area of the Steiner optic lens so the water molecules 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.
Options for Installing Rifle Optics on Firearms
Mounting approaches for scopes come in a couple of options. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally are made in quick release versions which use toss levers which enable rifle operators to quickly mount and dismount the scopes.
Hex Key Rifle Glass Ring Mounting Solutions
Basic, clamp-on type mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use double independent rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This kind of scope mount is exceptional for rifles which need a durable, unfailing mount which will not move 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 dedicated optics system on a long distance hunting or sniper competition rifle which will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount screws to prevent the hex screw threads from backing out after they are mounted tightly in place. An example of these rings are the 30mm style made by the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. A wide range of scopes can also be switched out if they all use a complementary designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving accuracy. These types of mounts come in convenient for rifles which are moved a lot, to take off the scope from the rifle for protection, or for optics which are used between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. Many scopes protect against moisture from entering the scope tube with a series of sealing O-rings which are water resistant. Generally, these scopes can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content avoidance for common use rifles, unless you intend on taking your rifle sailing and are worried about the scope still functioning if it goes over the side and you can still rescue the firearm.
Gas Purged Rifle Optic Tubes
Another element of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the optic is less altered by temperature changes and pressure variations from the outdoor environment which might potentially permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
