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 magnifying the target by using a series of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of many ecological factors like wind and elevation to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the target. Most contemporary rifle optics have about 11 parts which are arranged within and externally on the optic. These parts include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other elements. Learn about the eleven parts of scopes.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has determines where the reticle or crosshair is located relative to the scopes magnifying adjustments. It actually suggests the reticle is situated behind or before the magnification lens of the scope. Choosing the most effective type of rifle optic is dependent on what form of shooting you anticipate doing.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This triggers 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 amplified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards by using 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who have an idea for their target “hold over” and also “lead” equations for their long gun
- Shooters who do not mind the reticle is enlarged and requires more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away forms of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and proximities
- Shooters who desire a clearer optic sight picture with less space taken up by the larger size FFP reticle
Zoom for Scopes
The measure of scope zoom you need on your scope depends on the style of shooting you choose to do. Nearly every style of rifle glass gives some degree of magnification. The amount of zoom a scope gives is established by the dimension, density, and curves of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the opic. This denotes what the shooter is checking out through the scope is amplified times the power aspect of what can typically be seen by human eyes.
About Single Power Lens Optics
A single power rifle scope will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not adjust because it is a set power scope.
Adjustable Power Lens Scope Facts
Variable power rifle scopes can be tweaked between magnified levels. The power change is handled by the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope powers and the ranges where they could be successfully used. Consider that high power optics will not be as practical as lower powered glass since excessive magnification can be a detractor. The same relates to extended distances where the shooter needs to have enough power to see precisely where to properly aim the rifle at the target.
Details on Lens Covering
All cutting-edge rifle optic lenses are covered. Lens coating is a crucial element of a shooting system when thinking about high end rifle optics and scope equipment.
ED Versus HD Rifle Glass
Some optic producers will also use “HD” or high-definition lens finishings which take advantage of different processes, polarizations, chemicals, and aspects to extract separate colors and viewable target definition through the lens. This high-definition coating is often used with more costly high density glass which decreases light’s potential to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious over objects with hard edges and shapes as light hits the item from various angles.
Single Glass Lens Finish Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses usually have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope maker and how much you spent on it. Both the manufacturer and amount are indications of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Lens Coatings
Water on a scope’s lens does not improve maintaining a clear sight picture through a scope in any way. Lots of top of the line and high-end optic producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface of the Steiner glass lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Rifle Scope Installation Alternatives
Installing options for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also typically come in quick release variations which use manual levers which permit rifle operators to rapidly mount and remove the scopes.
Hex Key Optic Ring Mounting Solutions
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 two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range precision shooting. This type of scope mount is fine for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Rings
These types 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. Several scopes can also be swapped out if they all use a complementary style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach securely to a flat top type Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving precision. These kinds of mounts are useful and beneficial for rifles which are shipped a lot, to remove the scope glass from the rifle for protection, or for scopes which are chosen for use between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
What to Know About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. Most scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Rifle Glass Tube Gas Purging
Another component of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the scope is less influenced by climate changes and pressure distinctions from the external environment which could potentially enable water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
