What You Need to Know About Glass
Rifle scopes enable you to precisely align a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnifying the target by employing a set of lenses within the scope. The scope’s alignment can be adjusted to account for separate ecological elements like wind speed and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand precisely 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. A lot of modern rifle scopes have about 11 parts which are found internally and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, elevation turrets or dials, focus rings, and other elements. Learn about the eleven parts of rifle optics.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle scope is based on what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are very little
- Experienced shooters who understand their target “hold over” and “lead” correlations for their long gun
- Shooters who don’t mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Second Focal Plane Scope Info
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter distances and ranges
- Shooters who like a clearer optic sight picture with less area used up by the larger sized FFP reticle
Magnification for Optics
The amount of zoom a scope offers is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Optic Info
A single power rifle optic comes with a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust because it is a set power scope.
Info About 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 Correlation of Rifle Optics
Here are some advised scope powers and the distances where they may be successfully used. High power scopes will not be as useful as lower powered rifle scope glass due to the fact that too much magnification can be a bad thing. The exact same concept applies to longer ranges where the shooter needs increased power to see where to best aim the rifle at the target.
About Optic Lens Finishing
All modern rifle optic lenses are layered. There are various types and qualities of glass coverings. Lens coating can be an important element of a rifle when considering high-end rifle optics and scope systems. The glass lenses are one of the most crucial parts of the scope due to the fact that they are what your eye looks through while sighting a rifle in on the target. The covering on the lenses protects the lens surface area and even improves anti glare from excess daylight and color profiles.
Details on Rifle Optic Lens Coatings – HD Versus ED
Some optic manufacturers even use “HD” or high-def glass finishings which make the most of various procedures, components, chemical substances, and polarizations to extract different color ranges and viewable target definition through lenses. This HD coating is commonly used with more costly high density glass which drops light’s opportunity to refract by means of the lens glass. Some scope producers use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chroma spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be obvious over objects with hard outlines as light hits the object from particular angles.
Single Covering Versus Multi-Coating for Rifle Scopes
Various optic lenses can also have various finishings used to them. All lenses generally have at least some type of treatment or finish applied to them before being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while lowering glare and other less beneficial 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 manufacturers also make it a point to define if their optic lenses are covered or “multi” covered. This means the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can indicate that a manufacturer is taking numerous steps to combat different environmental factors like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally doesn’t always indicate the multi-coated lens is much better than a single layered lens. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in developing the rifle glass.
Hydrophobic Covering for Rifle Scopes
Water on an optical lens does not help with retaining a clear sight picture through a scope in any way. Numerous top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior surfaces of the Steiner optic lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads slide off of the scope to keep a clear, water free sight picture.
Choices for Installing Rifle Optics on Long Guns
Mounting approaches for scopes are available in a few choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also typically come in quick release versions which use throw levers which allow rifle operators to rapidly install and remove the scope.
Glass Mounting Solutions with Hex Key Rings
Normal, 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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope install is great 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 Glass Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable design mount, a number of scopes can also be swapped out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect solidly 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 while maintaining the original sighting settings. These types of mounts are useful and beneficial for shooting platforms which are carried a lot, to take off the optic from the rifle for protection, or for sight systems which are chosen for use between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. Many scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Optic Gas Purging
Another component of avoiding the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the glass is less affected by temperature shifts and pressure differences from the outdoor environment which might potentially enable water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
