What You Need to Know About Optics

Rifle scopes permit you to exactly align a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by using a series of lenses inside the scope. The scope’s alignment can be adapted to account for numerous natural things like wind and elevation increases to make up for bullet drop.

The scope’s function is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle optics have about eleven parts which are arranged inside and outside of the scope body. These parts consist of the rifle scope’s body, lenses, windage turrets or dials, objective focus rings, and other elements. See all eleven parts of optics.

The Styles of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has establishes where the reticle or crosshair lies relative to the scopes magnifying adjustments. It simply means the reticle is situated behind or before the magnification lens of the optic. Deciding on the most desired style of rifle optic depends on what form of hunting or shooting you anticipate undertaking.

Info on First Focal Plane Glass

Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This induces the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified range. For instance, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes work for:

  • Quick acquisition, far away types of shooting
  • Shooting scenarios where calculations are low
  • Experienced shooters who understand their aim point “hold over” and “lead” equations for their weapon
  • Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle

About Second Focal Plane Optics

Second focal plane scopes (SFP) feature the reticle behind the magnifying lens. This causes the reticle to stay at the exact same overall size in connection with the amount of magnification being used. The effect is that the reticle measurements change based on the zoom chosen to shoot over greater ranges given that the markings present various increments which fluctuate with the magnification. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular kinds of scopes work for:

  • Long distance styles of shooting where shooters have additional time to make ballistic calculations
  • Shooting where most shots occur within shorter spaces and ranges
  • Shooters who like a clearer optic picture without room used up by the larger sized FFP reticle

Details on Rifle Optic Magnification

The amount of zoom a scope offers is determined 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.

Single Power Lens Rifle Scopes

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

Adjustable Power Lens Rifle Optics

Variable power rifle scopes can be modified between magnified settings. The power change is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.

Optic Power Level and Ranges

Here are some recommended scope power settings and the distances where they can be effectively used. Consider that higher power scopes and optics will not be as efficient as lower magnification level scope and optics due to the fact that increased zoom can be a detractor. The exact same concept applies to extended distances where the shooter needs adequate power to see precisely where to properly aim the rifle at the target.

Details on Optic Lens Finishing

All current rifle optic and scope lenses are layered. Lens covering is a crucial aspect of a shooting platform when thinking about high end rifle optics and scope systems.

HD Versus ED Rifle Glass Lens Coatings

Some scope makers also use “HD” or high-def lense finishes which use various processes, polarizations, aspects, and chemicals to draw out numerous color ranges and viewable target definition through the lens. This high-def covering is normally used with higher density lens glass which brings down light’s ability to refract through the lens glass. Some scope manufacturers use “HD” to describe “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often noticeable around items with defined outlines as light hits the object from certain angles.

Single Finishing Versus Multi-Coating

Various optic lenses can even have different finishes applied to them. All lenses usually have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the finely tuned optic. It must have a covering put on it so that it will be optimally functional in many kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.

This lens treatment can offer protection to the lens from scratches while lowering glare and other less helpful 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 producers also make it a point to define if their optic lenses are covered or “multi” coated. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in building the rifle scope.

Hydrophobic Lens Finishing

Water on a scope lens does not help with keeping a clear sight picture through an optic in any way. Lots of top of the line or premium scope makers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It deals with the exterior of the Steiner glass lens so the H2O particles can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.

Alternatives for Mounting Rifle Optics on Long Guns

Mounting solutions for scopes are available in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also usually can be found in quick release variations which use manual levers which allow rifle operators to rapidly install and dismount the glass.

Scope Mounting Solutions with Hex Key Rings

Basic, clamp-on style mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on rifles. These varieties of scope mounts use double individual rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are made for long distance precision shooting. This type of scope mount is very good for rifles which need to have a long lasting, rock solid mount which will not change despite how much the scope is moved or jarring the rifle takes. These are the style of mounts you should get for a specialized scope setup on a reach out and touch someone hunting or interdiction rifle that will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screws from backing out after they are mounted tightly in place. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set generally costs around $200 USD

Quick-Release Cantilever Rifle Scope Ring Mounts

These types of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be switched out if they all use a similar style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach solidly to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving accuracy. These types of mounts are useful and handy for shooting platforms which are carried a lot, to remove the scope from the rifle for protection, or for scopes which are adopted in between multiple rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD

About Rifle Scope Tube Sealing and Gas Purging

Moisture inside your rifle optic can ruin a day on the range and your expensive optic by inducing fogging and producing residue inside of the scope’s tube. Most optics protect against humidity from going into the optical tube with a series of sealing O-rings which are waterproof. Typically, these optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness prevention for conventional use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are worried about the scope still performing if it is submerged in water and you can still rescue the rifle.

Gas Purged Glass Tubes

Another part of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less affected by temp changes and pressure differences from the outside environment which may possibly enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
