What You Need to Know About Glass
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnification by using a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account separate ecological factors like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the target. The majority of modern-day rifle optics have about 11 parts which are located within and outside of the scope body. These parts consist of the rifle scope’s body, lenses, windage dials or turrets, objective focus rings, and other components. Learn about the eleven parts of rifle scopes.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the optimal type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who know their aim point “hold over” as well as “lead” equations for their firearms
- Shooters who don’t mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane optics (SFP) feature the reticle behind the magnification lens. This triggers the reticle to remain at the very same dimensions relative to the level of zoom being used. The effect is that the reticle measurements adjust based on the magnification used to shoot over greater ranges because the reticle measurements represent different increments which change with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These styles of scopes are beneficial for:
- Far away forms of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots happen within much shorter distances and ranges
- Shooters who select a clearer optic sight picture with less space used up by the larger sized FFP reticle
Rifle Scope Magnification
The amount of magnification a scope offers is identified 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.
About Single Power Lens Glass
A single power rifle optic comes with a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change because it is fixed.
Variable Power Lens Rifle Scope Info
Variable power rifle scopes can be tweaked between magnified levels. The power change is performed using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Optic Power and Ranges
Here are some suggested scope power settings and the ranges where they could be efficiently used. Keep in mind that higher magnification scopes and optics will not be as efficient as lower magnification level optics due to the fact that excessive zoom can be a detractor. The very same idea goes for extended distances where the shooter needs adequate power to see precisely where to best aim the rifle.
Lens Covering for Optics
All modern-day rifle optic and scope lenses are coated. There are various types and qualities of lens coatings. Lens coating can be a crucial element of a rifle when considering high-end rifle optics and scope units. The glass lenses are one of the most critical parts of the scope since they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses offers protection to the lens surface area and improves anti glare capabilities from refracted sunlight and color discernibility.
HD Versus ED Lenses
Some optic manufacturers will also use “HD” or high-def lens finishes which employ various processes, elements, polarizations, and chemical applications to extract numerous colors and viewable target visibility through lenses. This high-def covering is commonly used with more costly high density lens glass which lowers light’s opportunity to refract by means of the lens glass. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how certain colors are presented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be obvious over things with defined shapes as light hits the object from certain angles.
Single Covering Versus Multi-Coating for Glass
Various optic lenses can also have various finishes applied to them. All lenses usually have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. This is since the lens isn’t just a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a covering placed on it so that the lens will be optimally functional in numerous types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope makers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This means the lens has had several treatments applied to them. If a lens gets numerous treatments, it can prove that a company is taking several steps to combat various natural elements like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This additionally doesn’t necessarily mean the multi-coated lens will perform better than a single coated lens. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.
What to Know About Anti-water Finish
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish.
Rifle Optic Installing Choices
Installing solutions for scopes come in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release variations which use throw levers which allow rifle operators to quickly install and dismount the optics.
Rifle Glass Mounting Solutions with Hex Key Rings
Standard, clamp design 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 made from 7075 T6 billet aluminum which is designed for long distance precision shooting. This type of scope mount is fine for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect it to a different rifle. Multiple scopes can even be swapped out if they all use a similar design mount. These types of mounts are handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness 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. Many scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Optic Tubes
Another part of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less impacted by temperature level shifts and pressure distinctions from the outdoor 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.
