Facts About Optics
Rifle scopes enable you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by utilizing a series of lenses within the scope. The scope’s alignment can be adapted for the consideration of many environmental aspects like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based upon the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of modern rifle scopes and optics have about eleven parts which are located within and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, windage dials, objective focus rings, and other components. Learn about the eleven parts of optics.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Opting for the optimal type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Optic Details
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are very little
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” ratios for their long guns
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Optics
Second focal plane glass (SFP) feature the reticle to the rear of the magnifying lens. This causes the reticle to stay at the exact same overall size relative to the amount of zoom being used. The effect is that the reticle dimensions alter based upon the magnification used to shoot over longer ranges considering that the reticle markings present different increments which fluctuate with the zoom level. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick reticle measurement. These particular types of glass are convenient for:
- Long distance kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most shots occur within much shorter ranges and distances
- Shooters who like a clearer optic sight picture with less area used up by the larger sized FFP reticle
Rifle Glass Magnification
The amount of zoom a scope offers is figured out 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 Glass Facts
A single power rifle optic uses a magnification number designator like 4×32. This suggests the magnification 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 fixed.
Adjustable Power Lens Rifle Glass Info
Variable power rifle scopes use variable power levels. 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.
Power Levels and Range
Here are some advised scope powers and the distances where they could be successfully used. Keep in mind that high power optics will not be as practical as lower magnification level glass because too much zoom can be a negative thing in certain situations. The exact same concept relates to extended distances where the shooter needs enough power to see exactly where to properly aim the rifle at the target.
Info on Scope Lens Covering
All contemporary rifle glass lenses are layered. Lens finish can be an essential aspect of a shooting system when looking at high end rifle optics and scope equipment.
Details on Lens Coatings – HD Versus ED
Some scope producers also use “HD” or high-definition lens finishes which use different methods, polarizations, chemicals, and aspects to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Rifle Glass Lens Covering Versus Multi-Coating
Various optic lenses can also have different coverings applied to them. All lenses normally have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.
This lens treatment can protect 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 layered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.
Hydrophobic Lens Finishes
Water on an optical lens does not help with keeping a clear sight picture through an optic at all. Numerous top of the line and high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It treats the exterior of the Steiner optic lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Rifle Scope Mounting Alternatives
Mounting solutions for scopes are available in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally are made in quick release variations which use toss levers which permit rifle operators to rapidly install and remove the optics.
Hex Key Rifle Glass 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 separate rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance accuracy shooting. This type of scope install is great for rifles which need a long lasting, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle before reattaching it to a different rifle. Several scopes can even be switched out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transported a lot, to remove the optic from the rifle for protection, or for scopes which are used between several rifles or are situationally focused.
Info Around Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your pricey optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
What to Know About Rifle Glass Tube Gas Purging
Another component of preventing the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the scope is less influenced by climate shifts and pressure variations from the external environment which may potentially 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 look for.
