What You Need to Know About Optics

Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target over a distance. They accomplish this through magnification by using a series of lenses within the scope. The scope’s alignment can be adapted to account for numerous environmental considerations like wind speed and elevation decreases to make up for bullet drop.

The scope’s purpose is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes have around eleven parts which are located within and on the exterior of the scope. These parts include the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other components. See all eleven parts of a rifle scope.

About Glass Types

Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has determines where the reticle or crosshair lies in regard to the optic’s zoom. It actually implies the reticle is situated behind or ahead of the magnification lens of the optic. Looking for the most effective type of rifle optic is dependent on what kind of hunting or shooting you plan on undertaking.

Info About First Focal Plane Glass

First focal plane glass (FFP) come with 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 outcome is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the exact same tick at 100 yards using 5x “zoom”. These kinds of scopes work for:

  • Quick acquisition, long distance kinds of shooting
  • Shooting circumstances where computations are low
  • Experienced shooters who know their aim point “hold over” and “lead” relationships for their long guns
  • Shooters who do not mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle

Second Focal Plane Scopes

Second focal plane glass (SFP) feature the reticle behind the magnifying lens. This induces the reticle to remain at the exact same size relative to the volume of magnification being used. The final result is that the reticle measurements alter based on the zoom used to shoot over greater ranges considering the reticle measurements present distinct increments which change with the magnification level. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These particular varieties of scopes are beneficial for:

  • Long distance kinds of shooting where shooters have extra time to make ballistic calculations
  • Shooting where most shots occur within shorter ranges and spaces
  • Shooters who select a clearer optic sight picture without space used up by the larger size FFP reticle

Magnification for Optics

The level of scope zoom you need depends upon the kind of shooting you want to do. Almost every type of rifle glass delivers some level of magnification. The volume of zoom a scope provides is identified by the diameter, thickness, and curves of the lenses within the rifle scope. The magnification of the optic is the “power” of the glass. This denotes what the shooter is looking at through the scope is amplified times the power aspect of what can usually be seen by human eyes.

About Single Power Lens Rifle Optics

A single power rifle optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change considering that it is a fixed power scope.

Variable Power Lens Glass Info

Variable power rifle scopes can be changed between magnification increments. It will list the magnification degree in a format like 2-10×32. These numbers indicate the magnification of the scope can be adjusted in between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power modification is accomplished using the power ring component of the scope near the back of the scope by the eye bell.

Power and Range

Here are some suggested scope powers and the distances where they could be successfully used. Highly magnified optics will not be as efficient as lower magnification level optics due to the fact that too much magnification can be a negative aspect depending on your shooting distance. The same idea goes for extended distances where the shooter needs adequate power to see where to best aim the rifle at the target.

Lens Covering for Rifle Scopes

All top teir rifle optic and scope lenses are coated. Lens finishing can be a significant aspect of a shooting platform when purchasing high end rifle optics and scope setups.

Info on Glass Lens Coatings – HD Versus ED

Some rifle glass makers will also use “HD” or high-def lense finishes that employ various processes, elements, polarizations, and chemicals to enhance different color ranges and viewable target visibility through lenses. This HD coating is often used with more costly, high density glass which drops light’s potential to refract by means of the lens glass. Some scope manufacturers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration may be noticeable over things with well defined shapes as light hits the object from certain angles.

Rifle Glass Lens Single Finishing Versus Multi-Coating

Different optic lenses can also have various finishings used to them. All lenses usually 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 safeguard the lens from scratches while reducing glare and other less useful 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 also make it a point to specify if their optic lenses are coated or “multi” coated. This indicates the lens has several treatments applied to them. If a lens gets several treatments, it can indicate that a maker is taking several steps to combat different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This also doesn’t always indicate the multi-coated lens will perform better than a single layered lens. Being “much better” depends on the producer’s lens treatment innovation and the quality of components used in building the rifle glass.

Anti-water Scope Lens Coating

Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Many top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic covering.

Glass Mounting Options

Installing solutions for scopes come in a couple of choices. There are the basic scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally come in quick release variations which use manual levers which permit rifle operators to rapidly mount and remove the scopes.

Optic 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is developed for long distance precision shooting. This type of scope install is excellent for rifles which need a resilient, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.

Optic Mounts with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for long guns which are transported a lot, to swap out the optic from the rifle for protection, or for optics which are used between multiple rifles.

Glass Tube Sealing and Gas Purging

Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by triggering fogging and creating residue inside of the scope tube. Most scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.

Info Around Scope Tube Gas Purging

Another part of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the optic is less influenced by climate shifts and pressure differences from the outside environment which may potentially 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 look for.
