What You Need to Know About Optics
Rifle scopes permit you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through zoom using a set of lenses inside the scope. The scope’s alignment can be adjusted for consideration of various natural aspects like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have about eleven parts which are arranged internally and outside of the optic. These optic pieces include the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the finest type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who recognize their aim point “hold over” and “lead” relationships for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Second Focal Plane Optic Details
Second focal plane optics (SFP) feature the reticle to the rear of the magnification 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.
- Long distance forms of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots take place within shorter distances and ranges
- Shooters who like a clearer optic picture with less area used up by the enlarged FFP reticle
Rifle Optic Zoom
The measure of scope magnification you need on your optic depends on the form of shooting you want to do. Almost every type of rifle scope supplies some level of zoom. The level of magnification a scope delivers is established by the dimension, density, and curvatures of the lens glass inside of the rifle optic. The magnifying level of the scope is the “power” of the scope. This indicates what the shooter is checking out through the scope is amplified times the power element of what can normally be seen by human eyes.
About Single Power Lens Rifle Optics
A single power rifle scope uses a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of optic can not fluctuate because it is set from the factory.
Adjustable Power Lens Scopes
Variable power rifle scopes can be tweaked between magnified levels. The power modification is handled by the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power and Ranges
Here are some advised scope power settings and the ranges where they can be efficiently used. High power optics will not be as efficient as lower magnification optics due to the fact that too much magnification can be a bad thing. The same idea applies to longer distances where the shooter needs to have increased power to see precisely where to properly aim the rifle at the target.
Optic Lens Coating
All contemporary rifle scope and optic lenses are covered. Lens coating can be a vital element of a rifle when considering high end rifle optics and scope equipment.
HD Versus ED Lenses
Some glass makers additionally use “HD” or high-definition lens coatings which take advantage of various processes, elements, polarizations, and chemical applications to draw out different color ranges and viewable target visibility through lenses. This HD covering is normally used with higher density lens glass which lowers light’s potential to refract by means of the lens glass. Some scope suppliers use “HD” to describe “ED” signifying extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration is often obvious around objects with hard edges and shapes as light hits the item from particular angles.
Single Finishing Versus Multi-Coating for Scopes
Various optic lenses can likewise have various finishings applied to them. All lenses usually have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while lowering 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 producer and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are covered or “multi” covered. This means the lens has had several treatments applied to the surfaces of the glass. If a lens receives several treatments, it can show that a producer is taking multiple steps to fight various environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This additionally doesn’t necessarily imply the multi-coated lens will perform better than a single layered lens. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of materials used in developing the rifle glass.
Optic Lens Hydrophobic Finishing
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic finish.
Choices for Installing Rifle Scopes on Long Guns
Installing approaches for scopes come in a couple of choices. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally can be found in quick release versions which use manual levers which enable rifle operators to quickly mount and remove the glass.
Glass Mounting Solutions with Hex Key Rings
Standard, clamp style 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 made from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope mount is fine for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle. If they all use a similar style mount, multiple scopes can also be switched out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are moved around a lot, to remove the glass from the rifle for protection, or for optics which are employed between a number of rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can ruin a day of shooting and your highly-priced optic by inducing fogging and making residue inside of the scope’s tube. The majority of scopes prevent wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Generally, these water-resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample wetness prevention for conventional use rifles, unless you anticipate taking your rifle sailing and are worried about the scope still functioning if it falls overboard and you can still find the gun.
Gas Purged Rifle Glass Tubes
Another part of avoiding the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is currently occupied by the gas, the glass is less affected by temp alterations and pressure distinctions from the outside environment which may possibly permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
