Rifle Glass Details
Rifle scopes enable you to exactly aim a rifle at various targets by aligning your eye with the target over a distance. They do this through magnification by utilizing a series of lenses within the scope. The scope’s alignment can be adapted for consideration of many natural aspects like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based on the sight picture you are seeing via the scope as you align the scope’s crosshair or reticle with the intended target. Most modern rifle optics have about 11 parts which are found within and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, modification dials, objective focus rings, and other components. See all eleven parts of a rifle optical system.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the optimal type of rifle optic depends on what type of shooting you plan to do.
First Focal Plane Glass
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 estimations are marginal
- Experienced shooters who know their aim point “hold over” and also “lead” correlations for their long gun
- Shooters who do not mind the reticle is bigger and uses up more visual eyesight space than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away kinds of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots happen within much shorter ranges and proximities
- Shooters who like a clearer optic sight picture with less room used up by the enlarged FFP reticle
Details on Scope Zoom
The amount of zoom a scope supplies is figured out by the size, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info About Fixed Power Lens Scopes
A single power rifle scope comes with a zoom number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not fluctuate because it is set from the factory.
About Adjustable Power Lens Optics
Variable power rifle scopes can be tweaked between magnified settings. The power change is handled using the power ring part of the scope near the back of the scope by the eye bell.
Glass Power Level and Ranges
Here are some recommended scope powers and the ranges where they can be successfully used. High power optics will not be as effective as lower magnification level scopes since too much zoom can be a negative aspect depending on your shooting distance. The exact same concept relates to longer ranges where the shooter needs adequate power to see exactly where to best aim the rifle at the target.
Lens Finish for Rifle Glass
All modern-day rifle optic and scope lenses are coated. Lens finishing can be a crucial element of a rifle’s setup when thinking about high end rifle optics and scope systems.
ED Versus HD Rifle Optics
Some scope producers also use “HD” or high-definition lens finishings which use various procedures, polarizations, chemicals, and aspects to draw out a wide range of colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Scopes
Various optic lenses can even have various finishes applied to them. All lenses normally 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 simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in lots of types of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while decreasing glare and other less advantageous 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 specify if their optic lenses are covered or “multi” covered. This implies the lens has had multiple treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can show that a company is taking multiple actions to combat various natural aspects like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally does not necessarily imply the multi-coated lens is much better than a single layered lens. Being “much better” hinges on the manufacturer’s lens treatment solutions and the quality of products used in building the rifle glass.
Glass Lens Anti-water Coating
Water on a lens doesn’t help with preserving a clear sight picture through a scope at all. Numerous top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish.
Options for Mounting Glass on Long Guns
Mounting options for scopes can be found in a couple of options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also generally can be found in quick release variations which use manual levers which permit rifle operators to quickly install and remove the glass.
Hex Key Scope Ring Mounting Solutions
Standard, clamp type mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on the tops of rifles. These kinds of scope mounts use a pair of independent rings to support the scope, and are made from 7075 T6 billet aluminum which are designed for far away precision shooting. This form of scope mount is very good for rifle systems which are in need of a long lasting, unfailing mount which will not change despite how much the scope is moved or abuse the rifle takes. These are the style of mounts you should get for a faithful optics setup on a reach out and touch someone hunting or competition rifle that will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used on the screws to keep the hex screw threads from wiggling out after they are mounted securely in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and attach 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 long guns which are transported 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 Rifle Scope Tubes
Wetness inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. The majority of optics protect against humidity from getting in the optical tube with a series of sealing O-rings which are water resistant. Generally, these water resistant scopes can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of moisture avoidance for common use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are concerned about the scope still performing if it goes over the side and you can still salvage the gun.
Scope Gas Purging
Another part of preventing the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the glass is less altered by temperature alterations and pressure differences from the outdoor environment which may possibly enable 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 seek out.
