What You Need to Know About Rifle Glass
Rifle scopes allow you to exactly align a rifle at different targets by aligning your eye with the target over a range. They do this through zoom using a series of lenses inside the scope. The scope’s alignment can be adjusted for consideration of various natural considerations like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing via the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern rifle optics have about eleven parts which are located inside and on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other components. See all eleven parts of an optic.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane a scope has decides where the reticle or crosshair lies in connection with the scopes magnifying adjustments. It simply indicates the reticle is behind or ahead of the magnifying lens of the optic. Deciding on the most effective style of rifle scope is based on what variety of shooting you plan on doing.
Info About First Focal Plane Scopes
First focal plane scopes (FFP) feature the reticle in front of the zoom lens. This causes the reticle to increase in size based on the extent of magnification being used. The result is that the reticle measurements are the same at the enhanced range 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 types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who understand their target “hold over” and also “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter ranges and distances
- Shooters who select a clearer optic picture without space used up by the bigger FFP reticle
Optic Magnification
The amount of magnification a scope offers is determined 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 Rifle Scope Details
A single power rifle scope or optic will have a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust since it is a fixed power scope.
Variable Power Lens Rifle Scopes
Variable power rifle scopes use variable power levels. The power modification is accomplished by the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range
Here are some suggested scope power settings and the distances where they can be efficiently used. Remember that high power optics and scopes will not be as effective as lower magnification level optics and scopes because too much magnification can be a detractor. The same goes for longer ranges where the shooter needs to have sufficient power to see where to best aim the rifle at the target.
Optic Lens Finish
All modern-day rifle optic lenses are coated. There are different types and qualities of finishings. When shopping for luxury rifle targeting units, Lens coating can be a very important aspect of defining the capability of the rifle. The glass lenses are among the most significant pieces of the optic because they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface and helps with anti glare capabilities from refracted direct sunlight and color presence.
HD Versus ED Lenses
Some scope manufacturers will also use “HD” or high-def glass finishes that use various procedures, rare earth compounds, polarizations, and elements to extract different color ranges and viewable target definition through the lens. This HD covering is often used with higher density glass which reduces light’s chance to refract through the lens glass. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass. ED handles how colors are represented on the chroma spectrum and the chromatic difference or aberration which is similarly called color distortion or fringing. Chromatic aberration can be noticeable over items with hard edges and shapes as light hits the object from particular angles.
Single Covering Versus Multi-Coating
Different scope lenses can also have different coatings applied to them. All lenses normally have at least some kind of treatment or covering applied to them before being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It becomes part of the finely tuned optic. It needs to have a finishing put on it so that it will be efficiently functional in lots of types of environments, degrees of sunlight (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing 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 producer and how much you paid for it.
Some scope makers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in building the rifle scope.
Rifle Optic Lens Anti-water Finish
Water on a lens does not help with preserving a clear sight picture through a scope at all. Many top of the line or high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface area 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 sheet off of the scope to preserve a clear, water free sight picture.
Rifle Optic Installation Options
Mounting solutions for scopes can be found in a few options. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use toss levers which permit rifle shooters to quickly install and remove the scopes.
Glass Mounting Solutions with Hex Key Rings
Normal, 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 designed for long distance precision shooting. This type of scope mount is fine for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used in between numerous rifles.
Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope tube. A lot of scopes avoid wetness from going into the scope tube with a system of sealing O-rings which are waterproof.
Rifle Scope Gas Purging
Another part of avoiding the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less influenced by climate changes and pressure distinctions from the external environment which could possibly allow 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.
