What You Need to Know About Glass
Rifle scopes enable you to specifically aim a rifle at different targets by lining up your eye with the target over a distance. They do this through zoom by using a set of lenses inside the scope. The scope’s alignment can be adapted to account for varied natural things like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes have around eleven parts which are found within and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, elevation dials, focus rings, and other components. See all eleven parts of optics.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane an optic has determines where the reticle or crosshair lies in regard to the scopes magnifying adjustments. It literally indicates the reticle is behind or in front of the magnifying lens of the optic. Deciding upon the best kind of rifle optic depends upon what kind of shooting or hunting you intend on undertaking.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are helpful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who recognize their aim point “hold over” and also “lead” relationships for their long gun
- Shooters who do not mind the reticle is enlarged and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the magnifying lens. This induces the reticle to remain at the exact same size in connection with the volume of zoom being used. The outcome is that the reticle dimensions change based on the zoom used to shoot over longer distances because the markings represent various increments which vary with the magnification. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These styles of glass are convenient for:
- Long distance types of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots take place within much shorter distances and ranges
- Shooters who would like a clearer optic picture without area used up by the enlarged FFP reticle
The quantity of zoom a scope offers is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass Details
A single power rifle optic and scope uses a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not fluctuate given that it is a fixed power optic.
Info About Variable Power Lens Optics
Variable power rifle scopes can be modified between magnified levels. The power modification is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range Correlations
Here are some recommended scope power levels and the distances where they can be efficiently used. Consider that higher power optics will not be as practical as lower powered scopes because increased zoom can be a negative thing in certain situations. The same concept relates to longer ranges where the shooter needs increased power to see exactly where to properly aim the rifle.
Details on Lens Covering
All state-of-the-art rifle optic and scope lenses are covered. Lens coating is a crucial aspect of a shooting platform when thinking about high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some rifle scope manufacturers will also use “HD” or high-definition glass coatings which use different procedures, components, chemicals, and polarizations to extract a wide range of color ranges and viewable target definition through the lens. This HD finishing is normally used with increased density glass which decreases light’s ability to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how certain colors are represented on the chroma spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration is often obvious around things with well defined shapes as light hits the item from certain angles.
Single Rifle Glass Lens Finishing Versus Multi-Coating
Different optic lenses can likewise have different coatings applied to them. All lenses typically have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less beneficial 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 covered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Hydrophobic Optic Lens Finish
Water on a scope’s lens does not support maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior surfaces of the Steiner scope lens so the water particles can not bind to it or develop surface tension. The outcome is that the water beads roll off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Rifle Optics on Firearms
Mounting options for scopes come in a couple of options. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also typically can be found in quick release versions which use manual levers which allow rifle shooters to quickly mount and remove the scopes.
Hex Key Rifle Optic Ring Mounts
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope mount is excellent for rifles which need a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Scope Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be switched out if they all use a compatible design mount. These types of mounts are handy for long guns which are carried a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles.
About Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. The majority of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Glass Gas Purging
Another element of avoiding the accumulation of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the glass is less influenced by climate changes and pressure variations from the outdoor environment which might possibly enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
