What You Need to Know About Glass
Rifle scopes permit you to specifically aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through zoom by utilizing a set of lenses inside the scope. The scope’s alignment can be adjusted to account for different ecological aspects like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of modern rifle optics have around eleven parts which are found inside and on the exterior of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials, objective focus rings, and other components. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane a scope has determines where the reticle or crosshair lies in regard to the optic’s zoom. It literally implies the reticle is behind or before the magnification lens of the optic. Selecting the most reliable style of rifle scope depends on what style of shooting or hunting you plan on undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This triggers the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the magnified distance as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” correlations for their long guns
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle behind the magnification lens. This causes the reticle to remain at the exact same scale relative to the level of magnification being used. The result is that the reticle measurements evolve based on the magnification chosen to shoot over greater distances due to the fact that the markings present distinct increments which change with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These varieties of glass are handy for:
- Far away types of shooting where shooters have more time to make ballistic calculations
- Shooting where most of the shots happen within shorter ranges and proximities
- Shooters who desire a clearer optic sight picture with less area taken up by the larger sized FFP reticle
Zoom for Scopes
The amount of magnification a scope provides is identified by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Scope Info
A single power rifle optic uses a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change given that it is a fixed power optic.
Adjustable Power Lens Glass Info
Variable power rifle scopes can be changed between magnification power levels. It will list the magnification degree in a format like 2-10×32. These numbers suggest the magnification of the scope could be changed between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power adaptation is accomplished by working with the power ring component of the scope near the back of the scope by the eye bell.
Rifle Glass Power Level and Range Correlation
Here are some suggested scope powers and the distances where they can be successfully used. Bear in mind that higher power optics and scopes will not be as practical as lower magnification level scopes since too much zoom can be a negative thing in certain situations. The exact same idea goes for longer distances where the shooter needs increased power to see where to best aim the rifle.
Lens Coating for Rifle Optics
All contemporary rifle optic lenses are layered. Lens covering can be a significant aspect of a rifle’s setup when looking into high end rifle optics and scope systems.
HD Versus ED Rifle Glass Lens Coatings
Some scope producers also use “HD” or high-definition glass coatings that use different procedures, elements, polarizations, and chemical applications to enhance different color ranges and viewable target definition through lenses. This high-def covering is commonly used with higher density glass which lowers light’s chance to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration may be noticeable around objects with well defined outlines as light hits the object from certain angles.
About Single Finish Versus Multi-Coating
Various optic lenses can also have various finishes applied to them. All lenses generally have at least some kind of treatment or covering applied to them before being used in a rifle scope or optic. This is since the lens isn’t simply 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 efficiently usable in many types of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less beneficial 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 makers also make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the producer’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Scope Lens Coating
Water on a scope lens doesn’t improve keeping a clear sight picture through a scope whatsoever. Lots of top of the line and premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the surface of the Steiner scope lens so the water particles can not bind to it or create surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Scope Mounting Choices
Installing solutions for scopes are available in a few options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use toss levers which enable rifle operators to quickly mount and remove the optics.
Hex Key Optic Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use a couple of separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range precision shooting. This type of scope install is wonderful for rifles which require a long lasting, rock solid 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 take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, a number of scopes can also be swapped out on the range. The quick detach mount style is CNC machined 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, taken off of the rifle, and remounted while retaining accuracy. These types of mounts are useful and convenient for rifles which are shipped a lot, to remove the glass from the rifle for protection, or for scopes which are used in between several rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Info Around Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can wreck a day on the range and your costly optic by inducing fogging and generating residue inside of the scope tube. A lot of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof. Generally, these water resistant scopes can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture content prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are worried about the scope still functioning if it goes overboard and you can still recover the gun.
What to Know About Rifle Optic Tube Gas Purging
Another part of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the optic is less influenced by condition alterations and pressure distinctions from the external environment which could potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
