What You Need to Know About Optics
Rifle scopes enable you to precisely align a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom by making use of a series of lenses inside the scope. The scope’s alignment can be adjusted for consideration of separate natural considerations like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle optics have about eleven parts which are found inside and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, elevation turrets or dials, objective focus rings, and other parts. See all eleven parts of an optic.
About Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the optimal type of rifle scope depends on what type of shooting you plan on doing.
Info on First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are minimal
- Experienced shooters who have an idea for their target “hold over” and also “lead” ratios for their firearms
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots take place within shorter spaces and ranges
- Shooters who like a clearer optic picture without space used up by the enlarged FFP reticle
Details on Scope Zoom
The extent of scope zoom you need on your optic is based on the style of shooting you plan to do. Practically every type of rifle glass supplies some degree of zoom. The amount of magnification a scope supplies is identified by the diameter, thickness, and curves of the lens glass within the rifle optic. The zoom of the optic is the “power” of the opic. This denotes what the shooter is observing through the scope is amplified times the power aspect of what can generally be seen by human eyes.
Single Power Lens Rifle Optics
A single power rifle scope comes with a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not fluctuate given that it is a set power scope.
Adjustable Power Lens Rifle Glass Info
Variable power rifle scopes use variable power levels. The power adjustment is accomplished by using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Scopes
Here are some suggested scope power settings and the distances where they may be efficiently used. Keep in mind that higher power scopes and optics will not be as effective as lower powered scope and optics because too much magnification can be a detractor. The same idea goes for extended ranges where the shooter needs sufficient power to see exactly where to best aim the rifle at the target.
Lens Covering for Scopes
All contemporary rifle scope lenses are layered. There are various types and qualities of coverings. Lens coating is an essential aspect of a rifle when considering high-end rifle optics and scope equipment. The lenses are among the most important parts of the scope considering they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses shields the lens surface area as well as assists with anti glare from excess direct sunlight and color discernibility.
HD Versus ED Lens Coatings
Some scope makers also use “HD” or high-definition lens finishes which use various methods, polarizations, aspects, and chemicals to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Various optic lenses can also have different coverings used to them. All lenses generally have at least some type of treatment or finishing used to them before being 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 covered lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are layered or “multi” covered. This suggests the lens has multiple treatments applied to the surfaces. If a lens receives several treatments, it can establish that a producer is taking numerous actions to fight various environmental elements like an anti-glare coating, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also does not necessarily imply the multi-coated lens is much better than a single covered lens. Being “much better” depends on the manufacturer’s lens treatment solutions and the quality of components used in creating the rifle scope.
Rifle Glass Lens Anti-water Finish
Water on a lens doesn’t assist with keeping a clear sight picture through a scope at all. Lots of top of the line and high-end scope makers will coat their lenses with a hydrophobic or hydrophilic anti-water coating.
Alternatives for Mounting Rifle Optics on Firearms
Installing approaches for scopes come in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also generally come in quick release versions which use throw levers which enable rifle shooters to rapidly install and dismount the scopes.
Hex Key Optic Ring Mounting Solutions
Standard, clamp style mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use a pair of independent rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This form of scope mount is very good for rifles which require a durable, unfailing mount which will not change despite just how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should get for a specialized scope setup on a long distance scouting or tournament long gun which will seldom need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to keep the hex screws from wiggling out after they are installed firmly in place. An example of these mounting rings are the 30mm style from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Several scopes can even be switched out if they all use a similar design mount. These types of mounts are convenient for long guns which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used between multiple rifles.
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by bringing about fogging and creating residue inside of the scope tube. Many scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Details on Glass Tube Gas Purging
Another component of preventing the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already occupied by the gas, the scope is less affected by temp changes and pressure variations from the external environment which may possibly permit water vapor to seep 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.
