Rifle Glass Info
Rifle scopes enable you to exactly align a rifle at various targets by lining up your eye with the target at range. They accomplish this through zoom by using a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of many natural aspects like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on the sight picture you are viewing using the optic as you align the scope’s crosshair or reticle with the target. Many contemporary rifle scopes have about 11 parts which are arranged inside and externally on the optic. These optic pieces include the rifle scope’s body, lenses, adjustment turrets or dials, objective focus rings, and other components. Learn about the eleven parts of glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the best type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are low
- Experienced shooters who have an idea for their aim point “hold over” and “lead” relationships for their firearm
- Shooters who don’t mind the reticle is bigger and uses up more visual sight room than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Far away forms of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots happen within shorter ranges and proximities
- Shooters who select a clearer optic picture with less room used up by the enlarged FFP reticle
Details on Rifle Glass Magnification
The quantity of zoom a scope offers is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Glass Facts
A single power rifle scope will have 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 magnification of this type of scope can not fluctuate since it is a set power scope.
About Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom amount in a format like 2-10×32. These numbers suggest the zoom of the scope could be set in between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power shift is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Glass
Here are some advised scope powers and the distances where they can be effectively used. Highly magnified scopes will not be as efficient as lower magnification glass considering that too much zoom can be a bad thing. The same concept relates to longer distances where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Lens Finishing for Rifle Optics
All state-of-the-art rifle optic lenses are coated. Lens covering can be an important aspect of a rifle’s setup when buying high end rifle optics and scope setups.
Details on Optic Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens coatings which use different processes, chemicals, aspects, and polarizations to draw out a wide range of colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Scopes
Various scope lenses can even have various coverings applied to them. All lenses generally have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many types of environments, degrees of light (full VS shade), and other shooting conditions.
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 producers also make it a point to define if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Details on Hydrophobic Finishing
Water on an optical lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line or premium optic makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the surface of the Steiner optic lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Choices for Mounting Rifle Scopes on Firearms
Mounting solutions for scopes can be found in a couple of choices. There are the basic scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also generally are made in quick release versions which use throw levers which permit rifle shooters to quickly install and dismount the scopes.
Hex Key Optic Ring Mounts
Basic, clamp-on type mounting scope rings use hex head screws to install to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use double separate rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This kind of scope mount is good for rifle systems which are in need of a resilient, hard use mount which will not shift despite just how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should get for a faithful scope system on a long distance hunting or sniper competition long gun that will pretty much never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screws from wiggling out after they are mounted safely in position. An example of these mounting rings are the 30mm type from Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach it to a different rifle. Numerous scopes can even be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifles which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle glass can wreck a day on the range and your costly optic by inducing fogging and generating residue inside of the scope’s tube. The majority of optics protect against humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Usually, these water resistant optics can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture avoidance for standard use rifles, unless you plan on taking your rifle aboard watercrafts and are concerned about the scope still performing if it is submerged in water and you can still rescue the gun.
About Rifle Scope Tube Gas Purging
Another component of preventing the accumulation of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the scope is less influenced by condition shifts and pressure differences from the external environment which could potentially allow water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
