What You Need to Know About Rifle Glass
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target using a set of lenses within the scope. The scope’s alignment can be dialed in for consideration of numerous environmental factors like wind and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern rifle scopes and optics have around 11 parts which are located within and externally on the scope body. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other components. See all eleven parts of optics.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the finest type of rifle glass is based around what type of shooting you plan on doing.
About First Focal Plane Scopes
First focal plane glass (FFP) include the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the level of magnification being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are very little
- Experienced shooters who recognize their target “hold over” and also “lead” equations for their firearms
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots take place within much shorter ranges and proximities
- Shooters who choose a clearer optic picture with less area taken up by the bigger FFP reticle
Zoom for Rifle Scopes
The quantity of zoom a scope offers is determined by the diameter, thickness, 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 Details
A single power rifle optic and scope will have a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change given that it is set from the factory.
Adjustable Power Lens Glass Info
Variable power rifle scopes can be adjusted between magnification increments. It will list the magnification amount in a configuration like 2-10×32. These numbers suggest the zoom of the scope could be set in between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power manipulation is accomplished by employing the power ring component of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some advised scope power levels and the distances where they may be efficiently used. Highly magnified glass will not be as effective as lower powered rifle scope glass because too much magnification can be a negative aspect depending on your shooting distance. The exact same idea goes for extended distances where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Lens Coating for Scopes
All contemporary rifle scope lenses are coated. There are different types and qualities of finishings. Lens finishing is an essential aspect of a rifle’s setup when considering high-end rifle optics and scope units. The glass lenses are one of the most vital components of the glass because they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface area and also improves anti glare from excess sunshine and color discernibility.
Details on Lens Coatings – HD Versus ED
Some scope brands also use “HD” or high-definition lens coatings which use various techniques, chemicals, aspects, and polarizations to draw out various colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating
Various optic lenses can also have various finishes applied to them. All lenses normally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
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 layered lens depends on the scope manufacturer 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. Being “much better” depends on the producer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Anti-water Lens Finish
Water on a lens does not help with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic covering.
Scope Installing Options
Installing options for scopes come in a couple of options. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also typically come in quick release variations which use manual levers which enable rifle operators to quickly mount and dismount the scopes.
Rifle Optic Mounting Solutions with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design 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 created for long distance accuracy shooting. This type of scope mount is perfect for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These kinds of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, multiple scopes can also be switched out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving precision. These kinds of mounts are useful and handy for shooting platforms which are transferred a lot, to take off the glass from the rifle for protection, or for optics which are used in between several rifles. An example of this mount type is the 30mm mount from the Vortex Optics brand. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle scope can mess up a day of shooting and your expensive optic by causing fogging and creating residue inside of the scope tube. Most scopes prevent wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Details on Scope Tube Gas Purging
Another component of preventing the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the glass is less altered by temp changes and pressure differences from the outside environment which may potentially allow water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
