Rifle Glass Details
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target over a range. They accomplish this through zoom by employing a set of lenses within the scope. The scope’s alignment can be adjusted for the consideration of different environmental elements like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are viewing with the optic as you line up the scope’s crosshair or reticle with the intended target. Most modern-day rifle scopes have about eleven parts which are arranged inside and externally on the scope. These parts include the rifle scope’s body, lenses, elevation turrets, focus rings, and other components. Learn about the eleven parts of glass.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the best type of rifle scope is based on what type of shooting you plan on doing.
First Focal Plane Scope Info
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who know their aim point “hold over” as well as “lead” equations for their firearm
- Shooters who don’t mind the reticle is enlarged and requires more visual sight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle behind the zoom lens. This induces the reticle to remain at the same overall size relative to the volume of magnification being used. The effect is that the reticle measurements adapt based on the zoom chosen to shoot over greater ranges considering that the markings represent distinct increments which fluctuate with the magnification. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These sorts of glass are useful for:
- Far away styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most of the shots take place within much shorter ranges and proximities
- Shooters who select a clearer optic picture without room used up by the enlarged FFP reticle
Scope Zoom
The extent of scope zoom you need on your glass depends upon the style of shooting you would like to do. Just about every style of rifle optic gives some degree of magnification. The quantity of magnification a scope gives is identified by the size, thickness, and curvatures of the lens glass inside of the rifle optic. The magnification level of the optic is the “power” of the opic. This denotes what the shooter is checking out through the scope is amplified times the power aspect of what can typically be seen by human eyes.
Single Power Lens Scope Info
A single power rifle scope uses a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not fluctuate considering that it is fixed.
Adjustable Power Lens Glass Info
Variable power rifle scopes can be modified between magnified levels. The power change is achieved 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 suggested scope power settings and the ranges where they could be efficiently used. Always remember that higher power scopes and optics will not be as efficient as lower powered scope and optics since too much zoom can be a negative thing in certain situations. The very same idea applies to extended distances where the shooter needs to have sufficient power to see precisely where to properly aim the rifle.
Rifle Scope Lens Coating
All current rifle scope and optic lenses are coated. Lens finish is an essential aspect of a rifle’s setup when buying high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some glass manufacturers even use “HD” or high-definition lens coverings that use different procedures, components, polarizations, and chemical applications to extract numerous color ranges and viewable definition through the lens. This high-definition covering is normally used with more costly high density glass which drops light’s ability to refract through the lens glass. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration may be obvious over things with hard edges and shapes as light hits the item from particular angles.
Rifle Glass Lens Single Finish Versus Multi-Coating
Various optic lenses can also have different coverings applied to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing 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 manufacturers likewise make it a point to define if their optic lenses are layered or “multi” coated. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can establish that a producer is taking numerous steps to fight different natural factors like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This additionally doesn’t necessarily mean the multi-coated lens will perform better than a single covered lens. Being “much better” depends upon the maker’s lens treatment techniques and the quality of materials used in developing the rifle glass.
What to Know About Anti-water Finish
Water on a lens doesn’t assist with maintaining a clear sight picture through a scope at all. Lots of top of the line and high-end optic companies will coat their lenses with a hydrophobic or hydrophilic covering.
Options for Installing Scopes on Firearms
Installing solutions for scopes are available in a few choices. There are the basic scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually are made in quick release versions which use manual levers which enable rifle operators to quickly mount and remove the scope.
Scope Mounting Solutions with Hex Key Rings
Standard, clamp type mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These varieties of scope mounts use two individual rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are created for long distance accuracy shooting. This kind of scope mount is exceptional for rifles which require a long lasting, hard use mount which will not move regardless of how much the scope is moved or abuse the rifle takes. These are the style of mounts you really want to have for a faithful optics setup on a reach out and touch someone hunting or sniper competition rifle which will rarely need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to keep the hex screws from wiggling out after they are installed tightly in position. An example of these rings are the 30mm type from the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a compatible design mount. These types of mounts are handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between multiple rifles or are situationally focused.
Sealing and Gas Purging for Scope Tubes
Moisture inside your rifle glass can spoil a day of shooting and your costly optic by triggering fogging and developing residue inside of the scope’s tube. A lot of scopes protect against wetness from going into the optical tube with a system of sealing O-rings which are waterproof. Typically, these water resistant scopes can be submerged underneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture avoidance for common use rifles, unless you anticipate taking your rifle sailing and are worried about the optic still functioning if it goes over the side and you can still rescue the gun.
Rifle Scope Gas Purging
Another element of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the glass is less affected by condition shifts and pressure variations from the outside environment which might possibly allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
