What You Need to Know About Rifle Glass
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target at range. They accomplish this through magnification by making use of a set of lenses within the scope. The scope’s alignment can be dialed in for consideration of varied natural things like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle scopes and optics have about 11 parts which are arranged within and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other elements. Learn about the eleven parts of rifle optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane an optic has decides where the reticle or crosshair is located in relation to the scopes magnifying adjustments. It literally suggests the reticle is located behind or before the magnifying lens of the scope. Deciding upon the best type of rifle glass is based on what style of hunting or shooting you intend on doing.
First Focal Plane Glass Details
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are minor
- Experienced shooters who know their target “hold over” and “lead” equations for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots happen within much shorter distances and ranges
- Shooters who choose a clearer optic picture with less space used up by the larger size FFP reticle
Details on Rifle Scope Zoom
The quantity of zoom a scope supplies is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Optics
A single power rifle optic and scope uses 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 change considering that it is set from the factory.
About Variable Power Lens Glass
Variable power rifle scopes can be modified between magnified settings. The power change is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some advised scope power settings and the distances where they can be successfully used. Highly magnified optics will not be as effective as lower magnification level optics because too much zoom can be a bad thing. The exact same idea applies to longer ranges where the shooter needs adequate power to see where to properly aim the rifle at the target.
Info on Lens Covering
All contemporary rifle scope and optic lenses are coated. There are different types and qualities of finishings. Lens covering can be an essential aspect of a rifle when contemplating high-end rifle optics and targeting equipment. The glass lenses are among the most critical parts of the glass because they are what your eye looks through while sighting a rifle in on the target. The finish on the lenses shields the lens surface and assists with anti glare capabilities from refracted direct sunlight and color perception.
Details on Lens Coatings – HD Versus ED
Some rifle scope makers even use “HD” or high-definition lense finishings which apply various procedures, aspects, chemicals, and polarizations to draw out various colors and viewable definition through the lens. This high-definition coating is typically used with higher density glass which brings down light’s potential to refract by means of the lens glass. Some scope producers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around objects with well defined shapes as light hits the item from various angles.
Single Covering Versus Multi-Coating for Rifle Glass
Different scope lenses can even have different coverings applied to them. All lenses normally have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just 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 optimally functional in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope maker and the amount you paid for it. Both the make and cost are indications of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This means the lens has several treatments applied to them. If a lens gets multiple treatments, it can establish that a manufacturer is taking several actions to combat different natural factors like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also doesn’t always mean the multi-coated lens will perform much better than a single covered lens. Being “better” depends upon the producer’s lens treatment techniques and the quality of components used in creating the rifle scope.
Glass Lens Hydrophobic Coating
Water on a lens does not help with preserving a clear sight picture through a scope at all. Many top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic coating.
Rifle Scope Mounting Alternatives
Mounting options for scopes can be found in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use manual levers which enable rifle operators to rapidly mount and remove the scope.
Optic Mounting Solutions with Hex Key Rings
Basic, clamp-on style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These styles of scope mounts use double detached rings to support the optic, and are normally made from 7075 T6 billet aluminum which are made for far away accuracy shooting. This kind of scope mount is excellent for rifle systems which need to have a long lasting, rock solid mount which will not move regardless of how much the scope is moved about or abuse the rifle takes. These are the design of mounts you really want to have for a faithful optics setup on a far away scouting or tournament rifle which will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to keep the hex screw threads from wiggling out after they are mounted firmly in place. An example of these rings are the 30mm style made by the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle before reattaching 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 long guns which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used in between several rifles or are situationally focused.
About Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can spoil a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope’s tube. Many optics protect against moisture from getting in the scope tube with a series of sealing O-rings which are water resistant. Usually, these scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough wetness 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 over the side and you can still recover the gun.
Details on Optic Tube Gas Purging
Another element of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the glass is less altered by condition shifts and pressure variations from the outside environment which could possibly 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.
