What You Need to Know About Rifle Glass
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnification by making use of a set of lenses within the scope. The scope’s alignment can be dialed in to take into account varied natural factors like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based upon the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern rifle optics have about eleven parts which are located within and on the exterior of the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane a scope has identifies where the reticle or crosshair lies in regard to the scopes magnifying adjustments. It actually means the reticle is located behind or before the magnification lens of the scope. Deciding upon the most reliable kind of rifle optic is based on what kind of hunting or shooting you anticipate doing.
Info on First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based on the amount of zoom being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the identical tick at 100 yards by using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are minor
- Experienced shooters who recognize their target “hold over” and “lead” ratios for their firearm
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
Second Focal Plane Optic Details
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots take place within shorter ranges and proximities
- Shooters who want a clearer optic picture without space used up by the larger sized FFP reticle
Scope Magnification
The quantity of zoom a scope offers is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Info on Fixed Single Power Lens Scopes
A single power rifle scope comes with a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not change since it is a set power scope.
Info About Variable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom level in a format like 2-10×32. These numbers imply the zoom of the scope can be adjusted between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power adaptation is accomplished by applying the power ring component of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Scopes
Here are some advised scope power settings and the ranges where they can be efficiently used. High power glass will not be as effective as lower magnification level glass because too much magnification can be a negative aspect depending on your shooting distance. The same concept applies to extended ranges where the shooter needs to have adequate power to see where to best aim the rifle.
Optic Lens Finish
All state-of-the-art rifle scope lenses are coated. Lens covering is an essential aspect of a rifle’s setup when purchasing high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope suppliers even use “HD” or high-definition lens coatings that employ different processes, components, chemical substances, and polarizations to draw out numerous color ranges and viewable definition through lenses. This high-def finishing is often used with greater density lens glass which decreases light’s opportunity to refract by means of the lens glass. Some scope corporations use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often noticeable over items with defined outlines as light hits the item from various angles.
Single Coating Versus Multi-Coating
Different optic lenses can also have different coverings applied to them. All lenses usually have at least some kind of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. This is because 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 it will be optimally functional in many kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing 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 manufacturer and the amount you spent paying for it. Both the make and cost are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. This suggests the lens has numerous treatments applied to them. If a lens gets several treatments, it can establish that a producer is taking numerous steps to combat different natural factors like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally doesn’t always suggest the multi-coated lens will perform much better than a single coated lens. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in building the rifle optic.
Anti-water Scope Lens Finish
Water on a scope’s lens does not improve preserving a clear sight picture through an optic at all. Numerous top of the line or high-end scope manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior of the Steiner scope lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Optic Mounting Choices
Mounting solutions for scopes come in a few options. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use toss levers which permit rifle shooters to rapidly install and remove the scopes.
Hex Key Optic Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope install is great for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts are handy for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between multiple rifles or are situationally focused.
About Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. A lot of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Scope Tubes
Another part of preventing the accumulation of moisture within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the scope is less influenced by temp shifts and pressure differences from the outside environment which may potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
