About Rifle Glass
Rifle scopes allow you to exactly aim a rifle at different targets by lining up your eye with the target at range. They do this through magnification by utilizing a series of lenses inside the scope. The scope’s alignment can be adapted for the consideration of many environmental elements like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have about 11 parts which are arranged internally and externally on the scope. These optic pieces include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other elements. See all eleven parts of a rifle scope.
About Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane a scope has establishes where the reticle or crosshair is located in connection with the scopes magnifying adjustments. It actually implies the reticle is behind or ahead of the magnifying lens of the scope. Deciding on the most suitable form of rifle optic depends upon what style of hunting or shooting you plan on undertaking.
First Focal Plane Optics
First focal plane optics (FFP) include the reticle ahead of the magnifying lens. This induces the reticle to increase in size based on the level of zoom being used. The outcome is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the identical tick at one hundred yards by using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who recognize their aim point “hold over” and “lead” relationships for their rifles
- Shooters who do not mind the reticle is enlarged and occupies more visual sight room than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance kinds of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who choose a clearer optic sight picture with less room taken up by the larger size FFP reticle
About Scope Magnification
The quantity of magnification a scope provides is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Optic Facts
A single power rifle scope and optic will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust given that it is a fixed power scope.
Variable Power Lens Optic Facts
Variable power rifle scopes use enhanced power. The power change is performed by 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 suggested scope powers and the distances where they could be successfully used. High power scopes will not be as effective as lower magnification level glass considering that too much magnification can be a bad thing. The same concept applies to longer distances where the shooter needs enough power to see where to properly aim the rifle.
Info on Rifle Glass Lens Coating
All contemporary rifle scope lenses are covered in special coatings. There are various types and qualities of glass coatings. When shopping for luxury rifle scope units, Lens covering can be an essential element of defining the capability of the rifle. The lenses are among the most crucial parts of the optic since they are what your eye sees through while sighting a rifle in on the target. The finishing on the lenses safeguards the lens exterior as well as helps with anti glare capabilities from excess daylight and color presence.
HD Versus ED Rifle Glass Lens Coatings
Some rifle scope producers will also use “HD” or high-def lense coverings which make the most of various procedures, rare earth compounds, elements, and polarizations to extract various color ranges and viewable target definition through the lens. This HD covering is often used with increased density glass which drops light’s chance to refract through the lens glass. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass. ED deals with how certain colors are represented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration is often noticeable around things with hard edges and shapes as light hits the item from specific angles.
Single Coating Versus Multi-Coating for Optics
Various optic lenses can likewise have various finishes used to them. All lenses usually have at least some type of treatment or covering used to them before being used in a rifle scope or optic.
This lens treatment can offer protection to 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 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 layered or “multi” covered. This implies the lens has several treatments applied to them. If a lens gets several treatments, it can prove that a maker is taking multiple steps to fight different natural elements like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also doesn’t necessarily suggest the multi-coated lens is much better than a single coated lens. Being “much better” depends on the manufacturer’s lens treatment solutions and the quality of glass used in constructing the rifle glass.
Scope Lens Hydrophobic Coating
Water on a scope lens doesn’t improve keeping a clear sight picture through an optic whatsoever. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the surface area of the Steiner glass lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Options for Mounting Rifle Glass on Long Guns
Installing options for scopes are available in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release versions which use manual levers which allow rifle operators to quickly mount and dismount the scopes.
Hex Key Rifle Scope Ring Mounting Solutions
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 different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long range precision shooting. This type of scope mount is perfect for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Multiple scopes can even be swapped out if they all use a similar style mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used between several rifles.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle scope can ruin a day of shooting and your costly optic by triggering fogging and producing residue inside of the scope tube. Most scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Optic Tubes
Another component of avoiding the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the scope is less impacted by temperature changes and pressure differences from the outdoor environment which could 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 look for.
