What You Need to Know About Optics
Rifle scopes permit you to specifically aim a rifle at various targets by aligning your eye with the target at range. They do this through zoom using a series of lenses inside the scope. The scope’s alignment can be dialed in to account for varied natural elements like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle optics have around eleven parts which are located inside and outside of the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other components. Learn about the eleven parts of glass.
About Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The kind of focal plane an optic has establishes where the reticle or crosshair lies in relation to the scopes magnification. It simply suggests the reticle is situated behind or before the magnification lens of the scope. Looking for the most ideal kind of rifle scope is based upon what sort of hunting or shooting you plan on undertaking.
Info About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who recognize their aim point “hold over” and also “lead” ratios for their firearms
- Shooters who do not mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Info on Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the magnifying lens. This causes the reticle to stay at the same overall size in connection with the amount of zoom being used. The effect is that the reticle dimensions shift based upon the magnification chosen to shoot over lengthier distances due to the fact that the reticle markings represent distinct increments which vary with the zoom. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick. These types of glass work for:
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who would like a clearer optic picture without area used up by the enlarged FFP reticle
Details on Glass Magnification
The measure of scope magnification you need on your scope is based on the form of shooting you intend to do. Pretty much every style of rifle scope offers some level of magnification. The amount of zoom a scope gives is established by the diameter, density, and curves of the lenses inside of the rifle scope. The magnification level of the scope is the “power” of the opic. This means what the shooter is looking at through the scope is amplified times the power factor of what can generally be seen by human eyes.
Info About Single Power Lens Glass
A single power rifle optic comes with a zoom number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate considering that it is set from the factory.
Variable Power Lens Rifle Glass Info
Variable power rifle scopes have adjustable power. It will note the magnification degree in a format like 2-10×32. These numbers suggest the magnification of the scope could be set between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power manipulation is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell piece.
The Power Level and Range Correlation of Rifle Optics
Here are some suggested scope power settings and the distances where they can be successfully used. High power glass will not be as effective as lower magnification level optics given that too much magnification can be a negative aspect depending on your shooting distance. The same concept goes for longer distances where the shooter needs enough power to see where to properly aim the rifle.
Lens Covering for Glass
All modern rifle scope and optic lenses are covered in special coatings. There are different types and qualities of glass finishings. When researching high end rifle optical systems, Lens finish can be a crucial element of a rifle. The glass lenses are one of the most essential components of the optic as they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses offers protection to the lens surface and also assists with anti glare capabilities from refracted direct sunlight and color discernibility.
HD Versus ED Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use different procedures, components, polarizations, and chemicals to draw out various colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Glass Lens Finish Versus Multi-Coating
Different optic lenses can even have different coatings applied to them. All lenses typically have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finish put on it so that it will be optimally functional in numerous kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can safeguard 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 covered lens depends on the scope maker and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Finish for Rifle Glass
Water on a lens does not assist with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic finishing.
Choices for Installing Scopes on Long Guns
Mounting options for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release variations which use toss levers which enable rifle shooters to quickly install and remove the optics.
Rifle Optic Mounting Solutions with Hex Key Rings
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount 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 are developed for long distance accuracy shooting. This type of scope mount is fine for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Numerous scopes can also be switched out if they all use a compatible style mount. These types of mounts are handy for rifles which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used in between multiple rifles or are situationally focused.
What to Know About Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day of shooting and your pricey optic by triggering fogging and making residue inside of the scope’s tube. Most scopes prevent wetness from entering the scope tube with a series of sealing O-rings which are waterproof. Usually, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample moisture content avoidance for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still performing if it is submerged in water and you can still find the gun.
Scope Gas Purging
Another part of avoiding the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less impacted by temperature level changes and pressure differences from the outside environment which may possibly permit water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
