What You Need to Know About Glass
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 zoom by using a series of lenses within the scope. The scope’s positioning can be adjusted for consideration of varied natural considerations like wind speed and elevation increases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle scopes and optics have about 11 parts which are found inside and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials or turrets, focus rings, and other elements. Learn about the eleven parts of scopes.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has identifies where the reticle or crosshair is located relative to the scopes zoom. It actually suggests the reticle is located behind or before the magnifying lens of the optic. Choosing the most desired type of rifle scope is based on what style of hunting or shooting you intend on undertaking.
Info About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the amount of magnification being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who recognize their target “hold over” as well as “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and requires more visual sight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle behind the magnification lens. This causes the reticle to stay at the very same overall size relative to the level of zoom being used. The end result is that the reticle measurements alter based upon the zoom applied to shoot over longer ranges considering that the reticle markings represent various increments which change with the magnification. In the FFP example with the SFP optic, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These styles of scopes are useful for:
- Far away forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within much shorter proximities and ranges
- Shooters who want a clearer optic picture without space taken up by the bigger FFP reticle
Details on Glass Zoom
The quantity of magnification a scope provides is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Rifle Optic Info
A single power rifle scope comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate since it is set from the factory.
Adjustable Power Lens Optic Facts
Variable power rifle scopes use enhanced power. The power change is performed using the power ring part of the scope near the back of the scope by the eye bell.
Optic Power and Ranges
Here are some recommended scope power settings and the distances where they may be effectively used. High power glass will not be as effective as lower magnification rifle scope glass because too much magnification can be a bad thing. The same concept applies to longer distances where the shooter needs adequate power to see exactly where to best aim the rifle at the target.
Details on Rifle Optic Lens Finish
All top of the line rifle optic lenses are covered. Lens finishing is an important element of a shooting system when considering high end rifle optics and scope systems.
HD Versus ED Rifle Scope Lens Coatings
Some scope makers also use “HD” or high-definition lens finishings which use various procedures, polarizations, elements, and chemicals to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Scopes
Different optic lenses can even have different finishings applied to them. All lenses generally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in lots of types of environments, degrees of sunshine (full light VS shaded), 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 coated lens depends on the scope producer and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This indicates the lens has had numerous treatments applied to the surfaces of the glass. If a lens receives several treatments, it can prove that a maker is taking numerous steps to fight different environmental factors like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This also does not necessarily imply the multi-coated lens will perform much better than a single coated lens. Being “much better” depends upon the manufacturer’s lens treatment solutions and the quality of components used in developing the rifle glass.
What to Know About Hydrophobic Finish
Water on a scope lens doesn’t help with keeping a clear sight picture through a scope whatsoever. Lots of top of the line and premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the surface area of the Steiner glass lens so the H2O molecules can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Choices for Mounting Rifle Scopes on Long Guns
Installing solutions for scopes come in a few options. There are the basic scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually come in quick release variations which use throw levers which enable rifle shooters to rapidly mount and dismount the glass.
Scope Mounts with Hex Key Rings
Standard, clamp type mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a pair of independent rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This form of scope mount is effective for rifle systems which are in need of a resilient, hard use mount which will not shift despite just how much the scope is moved or jarring the rifle takes. These are the type of mounts you should have for a faithful optics setup on a far away hunting or tournament rifle which will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used to protect against the hex screw threads from backing out after they are installed securely in position. An example of these rings are the 30mm type made by Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Glass Rings
These kinds of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle. If they all use a comparable style mount, a number of scopes can often be switched in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while preserving the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are transported a lot, to remove the optic from the rifle for protection, or for aiming systems which are utilized in between multiple rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and producing residue inside of the scope’s tube. Many optics protect against moisture from going into the optical tube with a system of sealing O-rings which are water resistant. Generally, these water-resistant scopes can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be plenty of wetness prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are worried about the scope still performing if it goes over the side and you can still rescue the gun.
Optic 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 currently occupied by the gas, the optic is less affected by temperature level changes and pressure variations from the external environment which may potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
