Glass Info
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target at range. They do this through magnifying the target by making use of a series of lenses within the scope. The scope’s positioning can be dialed in to account for varied natural things like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the target. Most contemporary rifle optics have about eleven parts which are found inside and outside of the scope. These optic pieces include the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other components. Learn about the eleven parts of glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the perfect type of rifle glass is based around what type of shooting you plan on doing.
Info on First Focal Plane Scopes
First focal plane scopes (FFP) include the reticle in front of the zoom lens. This induces the reticle to increase in size based upon the level of zoom being used. The outcome 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 100 yards without “zoom” is still the same tick at 100 yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are very little
- Experienced shooters who have an idea for their target “hold over” as well as “lead” correlations for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. This triggers the reticle to stay at the same dimensions relative to the level of magnification being used. The effect is that the reticle measurements shift based on the magnification applied to shoot over lengthier distances considering the reticle markings represent different increments which can vary with the zoom. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These sorts of glass are handy for:
- Far away types of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots occur within shorter distances and ranges
- Shooters who prefer a clearer optic picture without space used up by the enlarged FFP reticle
Zoom for Rifle Optics
The amount of magnification a scope offers is identified 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 Rifle Glass Details
A single power rifle scope comes with a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not fluctuate considering that it is fixed.
Variable Power Lens Rifle Glass
Variable power rifle scopes use variable power levels. The power adjustment is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Rifle Scopes
Here are some recommended scope power settings and the ranges where they can be successfully used. Remember that higher magnification optics will not be as practical as lower magnification level optics because increased magnification can be a detractor. The same goes for extended distances where the shooter needs to have enough power to see exactly where to properly aim the rifle at the target.
About Lens Finishes
All top teir rifle scope and optic lenses are coated. Lens covering is an important aspect of a rifle system when looking into high end rifle optics and scope setups.
ED Versus HD Scopes
Some scope manufacturers likewise use “HD” or high-definition lens finishings which use different methods, polarizations, chemicals, and elements to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Scope Lens Single Coating Versus Multi-Coating
Different scope lenses can even have various coatings applied to them. All lenses generally have at least some type of treatment or coating applied to them before being 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 carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally usable in many types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
Single covered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope company and just how much you spent on it. Both the manufacturer and amount are indications of the lens quality.
Some scope producers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in developing the rifle scope.
Anti-water Rifle Scope Lens Finish
Water on an optic’s lens does not support preserving a clear sight picture through a scope in any way. Numerous top of the line or high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the exterior surfaces of the Steiner optic 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 preserve a clear, water free sight picture.
Choices for Mounting Scopes on Firearms
Mounting solutions for scopes come in a couple of options. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually come in quick release versions which use manual levers which permit rifle shooters to quickly mount and remove the scope.
Hex Key Rifle Scope Rings
Standard, 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 different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope mount is excellent for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a similar style mount. These types of mounts are handy for long guns which are transported a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles or are situationally focused.
Info on Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. Most scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
What to Know About Rifle Glass Tube Gas Purging
Another component of avoiding the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the scope is less influenced by temperature level alterations and pressure differences from the outside environment which might potentially permit water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to look for.
