Information About Rifle Glass
Rifle scopes allow you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by using a set of lenses within the scope. The scope’s positioning can be adapted to account for numerous ecological aspects like wind and elevation increases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will hit based on the sight picture you are viewing using the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle optics have about 11 parts which are arranged within and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other parts. See all eleven parts of a scope.
About Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane a scope has determines where the reticle or crosshair is located in regard to the optic’s magnification. It simply means the reticle is located behind or ahead of the magnifying lens of the scope. Considering the most ideal form of rifle optic is based on what style of shooting or hunting you intend on doing.
First Focal Plane Glass Details
First focal plane optics (FFP) include the reticle in front of the zoom lens. This causes the reticle to increase in size based on the extent of magnification being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at one hundred yards with 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who have an idea for their aim point “hold over” and “lead” correlations for their long gun
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight area than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane glass (SFP) feature the reticle to the rear of the magnification lens. This triggers the reticle to stay at the exact same scale in relation to the volume of magnification being used. The final result is that the reticle dimensions adjust based on the zoom used to shoot over greater distances since the reticle measurements represent distinct increments which fluctuate with the magnification level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These styles of optics are useful for:
- Far away kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots happen within much shorter spaces and ranges
- Shooters who want a clearer optic picture with less space taken up by the bigger FFP reticle
Magnification for Scopes
The extent of scope magnification you need on your scope is based on the type of shooting you want to do. Nearly every kind of rifle optic provides some degree of zoom. The level of zoom a scope supplies is established by the dimension, thickness, and curves of the lens glass within the rifle scope. The magnifying level of the scope is the “power” of the opic. This suggests what the shooter is looking at through the scope is amplified times the power factor of what can normally be seen by human eyes.
Single Power Lens Optics
A single power rifle scope or optic uses a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust because it is a set power scope.
Info About Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be changed between magnification levels. It will note the magnification level in a format such as 2-10×32. These numbers indicate the zoom of the scope could be adjusted between 2x and 10x power. This also involves the power levels in-between 2 and 10. The power manipulation is achieved utilizing the power ring component of the scope near the back of the scope by the eye bell piece.
Scope Power and Range Correlation
Here are some advised scope powers and the distances where they could be effectively used. High power optics will not be as beneficial as lower powered rifle scope glass because too much magnification can be a negative aspect depending on your shooting distance. The very same idea applies to longer distances where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Details on Glass Lens Covering
All modern-day rifle glass lenses are coated. Lens covering can be a crucial aspect of a rifle system when considering high end rifle optics and scope setups.
Info on Rifle Optic Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens finishings which use various methods, components, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Coating Versus Multi-Coating for Scopes
Various scope lenses can also have different finishes applied to them. All lenses usually have at least some type of treatment or finish applied to them before being used in a rifle scope or optic. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It must have a covering applied to it so that the lens will be efficiently usable in many kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much money you paid for it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in developing the rifle scope.
Rifle Glass Lens Anti-water Coating
Water on an optic’s lens doesn’t help with maintaining a clear sight picture through a scope in any way. Lots of top of the line and high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface of the Steiner glass lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Choices for Installing Rifle Optics on Long Guns
Mounting options for scopes come in a couple of choices. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use toss levers which allow rifle operators to quickly mount and dismount the glass.
Hex Key Rifle Scope Ring Mounting Solutions
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 made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope mount is fine for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. Multiple scopes can also be switched out if they all use a similar designed mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining precision. These types of mounts come in handy for shooting platforms which are moved around a lot, to remove the glass from the rifle for protection, or for aiming systems which are chosen for use in between numerous rifles. An example of this mount style is the 30mm mount from Vortex Optics. It generally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can mess up a day on the range and your costly optic by causing fogging and creating residue inside of the scope tube. Many scopes protect against humidity from going into the scope tube with a series of sealing O-rings which are water resistant. Typically, these scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle sailing and are concerned about the optic still functioning if it goes over the side and you can still salvage the gun.
Gas Purged Rifle Glass Tubes
Another part of preventing the buildup of moisture within 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 optic is less influenced by climate alterations and pressure distinctions from the outside environment which may potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
