What You Need to Know About Glass

Rifle scopes permit you to precisely aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through zoom by employing a set of lenses within the scope. The scope’s alignment can be dialed in for the consideration of different ecological things like wind and elevation decreases to make up for bullet drop.

The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes and optics have around 11 parts which are arranged internally and outside of the scope. These parts consist of the rifle scope’s body, lenses, windage and elevation turrets, objective focus rings, and other components. See all eleven parts of a rifle optical system.

Rifle Scope Varieties

Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The style of focal plane an optic has decides where the reticle or crosshair is located relative to the optic’s zoom. It actually indicates the reticle is located behind or ahead of the magnification lens of the scope. Choosing the most ideal type of rifle optic depends upon what style of shooting you plan on undertaking.

First Focal Plane Optic Details

Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the level of zoom being used. The result is that the reticle measurements are the same at the magnified range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:

  • Quick acquisition, long distance kinds of shooting
  • Shooting scenarios where calculations are very little
  • Experienced shooters who recognize their aim point “hold over” and also “lead” relationships for their rifles
  • Shooters who don’t mind the reticle is enlarged and takes up more visual sight area than a SFP reticle

Second Focal Plane Scopes

Second focal plane scopes (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.

  • Far away kinds of shooting where shooters have additional time to make ballistic calculations
  • Shooting where most shots occur within shorter spaces and ranges
  • Shooters who choose a clearer optic sight picture without space taken up by the enlarged FFP reticle

Zoom for Rifle Glass

The extent of scope zoom you need on your optic depends on the style of shooting you choose to do. Almost every style of rifle scope supplies some level of zoom. The quantity of zoom a scope gives is determined by the size, density, and curves of the lens glass within the rifle optic. The magnification of the optic is the “power” of the opic. This signifies what the shooter is checking out through the scope is magnified times the power element of what can normally be seen by human eyes.

Single Power Lens Rifle Glass

A single power rifle optic will have a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change since it is fixed.

Adjustable Power Lens Rifle Optics

Variable power rifle scopes use enhanced power. The power modification is handled by the power ring part of the scope near the back of the scope by the eye bell.

Rifle Scope Power Level and Range Correlation

Here are some recommended scope powers and the distances where they could be effectively used. Remember that high power glass will not be as effective as lower powered optics and scopes since excessive magnification can be a bad thing. The very same idea applies to longer ranges where the shooter needs to have adequate power to see precisely where to best aim the rifle.

About Lens Finishing

All top of the line rifle scope lenses are covered. Lens finish can be an essential element of a shooting system when considering high end rifle optics and scope equipment.

ED Versus HD Optics

Some scope makers likewise use “HD” or high-definition lens finishings which use various processes, aspects, chemicals, and polarizations to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.

Single Finishing Versus Multi-Coating for Scopes

Various optic lenses can even have various coverings applied to them. All lenses generally have at least some type of treatment or covering applied to them before being used in a rifle scope or optic assembly. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in many types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.

This lens treatment can safeguard the lens from scratches while lowering glare and other less beneficial 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 producers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in building the rifle scope.

Hydrophobic Lens Finish

Water on an optic’s lens doesn’t assist with retaining a clear sight picture through a scope whatsoever. Numerous top of the line or premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the exterior surfaces of the Steiner glass lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.

Rifle Glass Mounting Options

Mounting approaches for scopes can be found in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also generally come in quick release variations which use toss levers which allow rifle operators to rapidly mount and dismount the optics.

Hex Key Rifle Scope Ring Mounting Solutions

Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is excellent for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.

Glass Mounting Solutions with Quick-Release Cantilever Rings

These types of quick-release rifle scope mounts can be used to rapidly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar style mount, a number of scopes can also be switched out in the field. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving precision. These kinds of mounts are useful and handy for shooting platforms which are transported a lot, to remove the scope glass from the rifle for protection, or for optics which are used in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD

Optic Tube Sealing and Gas Purging

Wetness inside your rifle glass can mess up a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. A lot of optics protect against humidity from going into the scope tube with a series of sealing O-rings which are water resistant. Generally, these scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture prevention for common use rifles, unless you anticipate taking your rifle on your motorboat and are worried about the scope still performing if it falls overboard and you can still salvage the gun.

Rifle Scope Gas Purging

Another component of avoiding the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Since this space is already taken up by the gas, the optic is less affected by temperature changes and pressure distinctions from the outdoor environment which may potentially enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
