What You Need to Know About Optics
Rifle scopes enable you to specifically align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by making use of a set of lenses within the scope. The scope’s alignment can be adapted for the consideration of separate natural aspects like wind speed and elevation increases or decreases 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 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 11 parts which are found internally and externally on the scope body. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. See all eleven parts of an optic.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Picking the best type of rifle scope is based around what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who know their aim point “hold over” and also “lead” ratios for their weapon
- Shooters who do not mind the reticle is enlarged and takes up more visual sight area than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnifying lens. This causes the reticle to remain at the exact same scale in relation to the level of zoom being used. The end result is that the reticle measurements change based upon the zoom applied to shoot over lengthier ranges due to the fact that the reticle measurements represent distinct increments which change with the magnification level. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular kinds of glass work for:
- Long distance kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within much shorter ranges and distances
- Shooters who prefer a clearer optic sight picture with less space used up by the bigger FFP reticle
Rifle Glass Magnification
The measure of scope zoom you require depends on the style of shooting you plan to do. Just about every type of rifle scope delivers some degree of zoom. The amount of zoom a scope provides is identified by the size, density, and curves of the lens glass inside of the rifle scope. The zoom of the scope is the “power” of the scope. This signifies what the shooter is looking at through the scope is amplified times the power element of what can typically be seen by human eyes.
Single Power Lens Rifle Optic Facts
A single power rifle scope will have 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 optic can not change since it is fixed.
Variable Power Lens Optic Details
Variable power rifle scopes have adjustable power. It will note the magnification amount in a configuration like 2-10×32. These numbers suggest the magnification of the scope can be set between 2x and 10x power. This always involves the powers in-between 2 and 10. The power adjustment is achieved by applying the power ring part of the scope near the back of the scope by the eye bell piece.
The Power Level and Range of Scopes
Here are some suggested scope power levels and the ranges where they can be efficiently used. Remember that high power glass will not be as effective as lower magnification level glass due to the fact that too much zoom can be a bad thing. The exact same idea applies to longer ranges where the shooter needs to have adequate power to see exactly where to properly aim the rifle.
Details on Lens Coatings
All current rifle scope lenses are coated. Lens finish is an essential element of a rifle system when buying high end rifle optics and scope equipment.
ED Versus HD Rifle Optics
Some optic companies even use “HD” or high-def lens coatings that make the most of different procedures, chemicals, components, and polarizations to extract numerous color ranges and viewable target definition through lenses. This high-definition coating is normally used with greater density lens glass which lowers light’s potential to refract through the lens glass. Some scope producers 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 difference which is similarly called color distortion or fringing. Chromatic aberration is often obvious over objects with hard outlines as light hits the object from various angles.
Rifle Glass Lens Single Finish Versus Multi-Coating
Various optic lenses can also have different finishes used to them. All lenses generally have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope maker and how much you paid for it.
Some scope producers similarly make it a point to specify if their optic lenses are layered or “multi” coated. Being “better” depends on the producer’s lens treatment technology and the quality of products used in constructing the rifle scope.
Rifle Scope Lens Anti-water Finish
Water on a scope lens does not support keeping a clear sight picture through a scope at all. Numerous top of the line or high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for 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 move off of the scope to preserve a clear, water free sight picture.
Choices for Installing Rifle Optics on Long Guns
Mounting approaches for scopes are available in a few choices. 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 typically can be found in quick release versions which use toss levers which enable rifle operators to quickly install and dismount 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 mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope install is fine for rifles which require a resilient, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Glass Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be swapped out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used between several rifles or are situationally focused.
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle optic can ruin a day of shooting and your highly-priced optic by triggering fogging and generating residue within the scope tube. The majority of optics protect against wetness from going into the scope tube with a series of sealing O-rings which are water resistant. Normally, these optics can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient humidity avoidance for conventional use rifles, unless you plan on taking your rifle aboard a watercraft and are concerned about the optic still performing if it is submerged in water and you can still retrieve the firearm.
Glass Gas Purging
Another element of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the glass is less influenced by climate shifts and pressure differences from the outside environment which might possibly allow 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 look for.
