Info Rifle Optics
Rifle scopes allow you to specifically align a rifle at different targets by lining up your eye with the target over a range. They accomplish this through zoom by making use of a set of lenses within the scope. The scope’s positioning can be adjusted for consideration of separate environmental considerations like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit 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. A lot of contemporary rifle optics have around eleven parts which are found internally and on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, elevation dials, focus rings, and other parts. Learn about the eleven parts of glass.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane a scope has determines where the reticle or crosshair is located in relation to the optic’s magnifying adjustments. It literally means the reticle is located behind or in front of the magnification lens of the scope. Choosing the most suitable form of rifle glass is based upon what style of hunting or shooting you intend on doing.
Info on First Focal Plane Scopes
First focal plane optics (FFP) include the reticle in front of the magnification lens. This causes the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are small
- Experienced shooters who recognize their target “hold over” and “lead” relationships for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane glass (SFP) feature the reticle behind the zoom lens. This causes the reticle to remain at the very same overall size relative to the quantity of magnification being used. The end result is that the reticle measurements change based upon the zoom used to shoot over longer ranges since the reticle markings represent various increments which vary with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These particular types of optics work for:
- Far away styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who would like a clearer optic sight picture without area used up by the bigger FFP reticle
Rifle Scope Magnification
The amount of zoom a scope offers is figured out 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.
Fixed Single Power Lens Glass Details
A single power rifle scope or optic uses a zoom number designator like 4×32. This suggests 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 fixed.
About Variable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification levels. It will note the zoom level in a configuration like 2-10×32. These numbers imply the zoom of the scope could be adjusted between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adaptation is accomplished by working with 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 recommended scope powers and the distances where they can be successfully used. Bear in mind that high power optics will not be as practical as lower magnification level scope and optics since increased magnification can be a bad thing. The same idea applies to longer distances where the shooter needs to have enough power to see exactly where to best aim the rifle.
Lens Covering for Glass
All modern-day rifle glass lenses are covered. Lens covering can be a significant element of a rifle’s setup when thinking about high end rifle optics and scope systems.
HD Versus ED Lenses
Some scope manufacturers also use “HD” or high-definition lens coverings which use various methods, elements, polarizations, and chemicals to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Optic Lens Single Coating Versus Multi-Coating
Various optic lenses can also have different coverings applied to them. All lenses usually have at least some kind of treatment or finish applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. 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 lots of kinds of environments, degrees of light (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 safeguard the lens from scratches while reducing 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 upon the scope company and how much money you spent on it. Both the make and cost are indications of the lens quality.
Some scope producers also make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Optic Lens Hydrophobic Finishing
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic finishing.
Alternatives for Mounting Rifle Glass on Firearms
Installing options for scopes can be found in a few options. There are the standard scope rings which are individually installed to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also generally come in quick release versions which use throw levers which permit rifle shooters to rapidly mount and remove the optics.
Hex Key Optic Rings
Standard, 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope install is fine for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Several scopes can even be swapped out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between multiple rifles.
Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can wreck a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope’s tube. A lot of scopes protect against moisture from going into the optical tube with a series of sealing O-rings which are water resistant. Normally, these water-resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity avoidance for standard use rifles, unless you anticipate taking your rifle aboard watercrafts and are concerned about the scope still working if it falls overboard and you can still retrieve the rifle.
What to Know About Scope Tube Gas Purging
Another part of avoiding the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the scope is less influenced by temp alterations 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 exist. These are good qualities of a good rifle scope to look for.
