Info About Rifle Optics
Rifle scopes allow you to exactly align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through zoom using a series of lenses within the scope. The scope’s alignment can be adapted for consideration of different ecological things like wind speed and elevation increases to account for bullet drop.
The scope’s function is to understand precisely where the bullet will land based upon the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended point of impact. Many contemporary rifle scopes and optics have around 11 parts which are found within and outside of the scope body. These scope parts include the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other elements. Learn about the eleven parts of glass.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the best type of rifle glass depends on what type of shooting you plan to do.
About First Focal Plane Scopes
First focal plane glass (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based upon the extent of magnification being used. The outcome is that the reticle measurements are the same at the amplified range 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 very same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting situations where calculations are minor
- Experienced shooters who know their target “hold over” and also “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and takes up more visual sight space than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane glass (SFP) feature the reticle to the rear of the zoom lens. This induces the reticle to remain at the same scale relative to the level of magnification being used. The outcome is that the reticle measurements adjust based upon the magnification used to shoot over greater distances since the reticle markings represent distinct increments which differ with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick. These particular styles of glass are handy for:
- Long distance forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots take place within shorter distances and ranges
- Shooters who like a clearer optic picture without area used up by the bigger FFP reticle
Zoom for Scopes
The quantity of scope magnification you need on your glass depends on the type of shooting you would like to do. Practically every type of rifle glass gives some degree of magnification. The level of zoom a scope gives is determined by the dimension, thickness, and curves of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope. This implies what the shooter is observing through the scope is magnified times the power factor of what can normally be seen by human eyes.
Fixed Single Power Lens Rifle Optic Info
A single power rifle scope uses a zoom 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 type of scope can not change because it is a fixed power scope.
Adjustable Power Lens Optics
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification degree in a format like 2-10×32. These numbers indicate the magnification of the scope could be changed in between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power manipulation is accomplished by operating the power ring component of the scope near the back of the scope by the eye bell.
The Power and Range of Rifle Scopes
Here are some recommended scope power levels and the distances where they could be successfully used. Highly magnified optics will not be as effective as lower magnification level optics due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The exact same idea goes for extended distances where the shooter needs sufficient power to see where to properly aim the rifle at the target.
Info on Rifle Scope Lens Finish
All current rifle optic lenses are layered. Lens coating is an essential element of a shooting system when thinking about high end rifle optics and scope equipment.
Details on Optic Lens Coatings – HD Versus ED
Some rifle glass makers even use “HD” or high-definition glass finishes that use various processes, rare earth compounds, components, and polarizations to enhance different color ranges and viewable definition through lenses. This high-definition finish is frequently used with more costly, high density lens glass which reduces light’s ability to refract through the lens glass. Some scope brands use “HD” to refer to “ED” indicating extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious around things with defined shapes as light hits the item from particular angles.
Single Coating Versus Multi-Coating
Different optic lenses can also have different finishes applied to them. All lenses typically have at least some kind of treatment or covering applied to them before being used in a rifle scope or optic assembly. Because the lens isn’t simply 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 efficiently functional in lots of kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers likewise make it a point to define if their optic lenses are layered or “multi” coated. This implies the lens has numerous treatments applied to the surfaces of the glass. If a lens gets several treatments, it can prove that a maker is taking numerous steps to combat different environmental elements like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This additionally doesn’t always indicate the multi-coated lens is better than a single coated lens. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in developing the rifle glass.
Glass Lens Anti-water Finish
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Scope Installation Choices
Installing approaches for scopes come in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also generally come in quick release variations which use manual levers which allow rifle shooters to quickly install and remove the scope.
Hex Key Glass Rings
Standard, 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 separate rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope install is wonderful for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Ring Mounting Solutions
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. Numerous scopes can even be switched out if they all use a similar design mount. These types of mounts are handy for rifles which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between several rifles.
About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day on the range and your costly optic by resulting in fogging and generating residue within the scope’s tube. Many optics protect against moisture from going into the scope tube with a system of sealing O-rings which are waterproof. Typically, these water resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for standard use rifles, unless you intend on taking your rifle boating and are worried about the optic still functioning if it is submerged in water and you can still recover the rifle.
Info Around Rifle Scope Tube Gas Purging
Another part of avoiding the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this space is already occupied by the gas, the optic is less impacted by temperature level changes and pressure variations from the outdoor environment which may potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
