Rifle Glass Information
Rifle scopes permit you to precisely align a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target by employing a series of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of different environmental considerations like wind and elevation to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended target. Most contemporary rifle scopes have about eleven parts which are found within and on the exterior of the scope body. These scope parts include the rifle scope’s body, lenses, windage dials, focus rings, and other parts. Learn about the eleven parts of optics.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the perfect type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optic Info
First focal plane optics (FFP) come with the reticle before the magnification lens. This causes the reticle to increase in size based upon the level of zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified range. For instance, one tick on a mil-dot reticle at one hundred yards without having “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 circumstances where estimations are marginal
- Experienced shooters who recognize their target “hold over” and “lead” correlations for their weapon
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) come with 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 increased time to make ballistic estimations
- Shooting where most shots take place within much shorter spaces and ranges
- Shooters who like a clearer optic picture without area taken up by the enlarged FFP reticle
About Rifle Optic Magnification
The quantity of zoom a scope provides is figured out by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Glass
A single power rifle optic comes with a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not fluctuate given that it is fixed.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power adjustment is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Glass
Here are some recommended scope powers and the ranges where they may be effectively used. Consider that higher power optics will not be as practical as lower powered scope and optics due to the fact that too much magnification can be a detractor. The same concept goes for extended distances where the shooter needs adequate power to see exactly where to properly aim the rifle at the target.
Lens Covering for Rifle Glass
All contemporary rifle optic and scope lenses are covered in special coatings. There are different types and qualities of lens finishes. When considering high end rifle optical units, Lens finish can be a critical element of defining the capability of the rifle. The glass lenses are among the most key pieces of the optic considering that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses offers protection to the lens surface and even helps with anti glare capabilities from refracted sunlight and color presence.
HD Versus ED Scope Lens Coatings
Some scope producers also use “HD” or high-def lens coatings that make the most of various processes, polarizations, chemicals, and elements to enhance separate colors and viewable target definition through lenses. This high-definition covering is frequently used with more costly high density glass which lowers light’s potential to refract through the lens glass. Some scope makers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are represented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be obvious over objects with defined outlines as light hits the object from particular angles.
Rifle Glass Lens Single Coating Versus Multi-Coating
Different optic lenses can also have various finishes applied to them. All lenses normally have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. This is since 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 it will be efficiently usable in numerous types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is usually a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and just how much you paid for it. Both are indicators of the lens quality.
Some scope makers likewise make it a point to define if their optic lenses are layered or “multi” coated. This means the lens has numerous treatments applied to the surfaces of the glass. If a lens gets several treatments, it can establish that a manufacturer is taking multiple actions to combat different natural elements like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally does not necessarily indicate the multi-coated lens is much better than a single coated lens. Being “much better” hinges on the maker’s lens treatment techniques and the quality of components used in creating the rifle glass.
Scope Lens Anti-water Finishing
Water on an optic’s lens does not help with retaining a clear sight picture through an optic whatsoever. Numerous top of the line and premium scope producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this type of treatment. It treats the exterior of the Steiner scope lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Choices for Installing Glass on Firearms
Mounting solutions for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally can be found in quick release variations which use throw levers which enable rifle shooters to quickly install and dismount the scope.
Hex Key Rifle Optic Rings
Normal, 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 two separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long range precision shooting. This type of scope mount is perfect for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle. If they all use a comparable style mount, a number of scopes can often be swapped out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining accuracy. These types of mounts are useful and handy for rifles which are transferred a lot, to remove the glass from the rifle for protection, or for optics which are utilized in between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
What to Know About Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. A lot of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Info on Optic Tube Gas Purging
Another component of preventing the buildup 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 scope is less influenced by condition alterations and pressure distinctions from the outside environment which might 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.
