Information Rifle Optics
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target over a range. They do this through zoom by using a set of lenses within the scope. The scope’s positioning can be adjusted for consideration of varied natural aspects like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to understand exactly where the bullet will land based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the target. Many modern rifle scopes and optics have about eleven parts which are arranged internally and on the exterior of the scope body. 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 optical system.
About Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has identifies where the reticle or crosshair is located relative to the scopes magnifying adjustments. It simply suggests the reticle is situated behind or before the magnification lens of the optic. Deciding on the most effective sort of rifle glass is dependent on what type of shooting you intend on doing.
First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who have an idea for their target “hold over” and also “lead” ratios for their long gun
- Shooters who don’t mind the reticle is enlarged and requires more visual sight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) include 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.
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots happen within much shorter proximities and ranges
- Shooters who desire a clearer optic picture with less area used up by the larger size FFP reticle
Zoom for Glass
The quantity of zoom a scope offers 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 Optic Info
A single power rifle scope and optic uses a magnification number designator like 4×32. This implies 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 considering that it is fixed.
About Variable Power Lens Glass
Variable power rifle scopes can be tweaked between magnified levels. The power modification is accomplished using the power ring part of the scope near the rear of the scope by the eye bell.
Scope Power and Ranges
Here are some suggested scope powers and the ranges where they can be efficiently used. High power optics will not be as beneficial as lower magnification optics since too much magnification can be a bad thing. The same idea goes for longer ranges where the shooter needs adequate power to see precisely where to best aim the rifle at the target.
Lens Coating for Rifle Optics
All modern-day rifle optic lenses are coated. There are various types and qualities of glass lens coatings. When shopping for high end rifle optics and scope devices, Lens finish can be a significant aspect of a rifle. The glass lenses are one of the most crucial parts of the scope considering they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses shields the lens exterior and improves anti glare capabilities from refracted direct sunlight and color profiles.
Info on Optic Lens Coatings – HD Versus ED
Some scope manufacturers also use “HD” or high-definition lens coverings which use different processes, polarizations, components, and chemicals to draw out different 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.
Optic Lens Single Finishing Versus Multi-Coating
Different optic lenses can also have various coverings 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 since the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It needs to have a finish put on it so that it will be efficiently functional in many kinds of environments, degrees of sunshine (full VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends upon the scope developer and just how much you spent paying for it. The scope’s maker and cost are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” covered. This suggests the lens has had multiple treatments applied to the surfaces. If a lens receives several treatments, it can indicate that a manufacturer is taking numerous actions to fight different environmental aspects like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally doesn’t always suggest the multi-coated lens is much better than a single coated lens. Being “much better” depends upon the manufacturer’s lens treatment technology and the quality of products used in creating the rifle glass.
Hydrophobic Covering for Rifle Glass
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Many top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finishing.
Rifle Glass Installation Options
Mounting approaches for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also normally can be found in quick release versions which use toss levers which allow rifle shooters to quickly install and dismount the glass.
Rifle Glass Mounts with Hex Key Rings
Basic, clamp-on type mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These forms of scope mounts use two independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are designed for long distance precision shooting. This kind of scope mount is good for rifles which need a resilient, unfailing mount which will not shift no matter just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should have for a faithful optics setup on a long distance hunting or competitors long gun which will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to protect against the hex screws from wiggling out after they are installed firmly in position. An example of these mounting rings are the 30mm style from the Vortex Optics brand. The set usually costs around $200 USD
Quick-Release Cantilever Optic Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle. If they all use a similar style mount, a number of scopes can often be swapped out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining accuracy. These types of mounts come in beneficial for rifles which are hauled around a lot, to remove the optic from the rifle for protection, or for sight systems which are employed between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another component of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the scope is less affected by temp shifts and pressure differences from the external environment which could possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
