What You Need to Know About Optics
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target over a distance. They do this through zoom using a series of lenses inside the scope. The scope’s positioning can be adapted for consideration of numerous environmental factors like wind speed and elevation increases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the intended target. Most modern-day rifle optics have about eleven parts which are arranged internally and externally on the optic. These scope parts include the rifle scope’s body, lenses, windage dials, focus rings, and other components. See all eleven parts of a scope.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane a scope has decides where the reticle or crosshair is located relative to the scopes magnifying adjustments. It actually implies the reticle is behind or in front of the magnifying lens of the optic. Picking the best type of rifle glass depends on what kind of shooting or hunting you anticipate undertaking.
First Focal Plane Glass Facts
First focal plane optics (FFP) feature the reticle ahead of the magnification lens. This triggers the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who understand their target “hold over” and “lead” equations for their rifles
- Shooters who do not mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
Info About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle to the rear of the zoom 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.
- Long distance styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who prefer a clearer optic picture without area used up by the larger sized FFP reticle
Rifle Glass Magnification
The amount of zoom a scope provides is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Optics
A single power rifle scope comes with a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not fluctuate considering that it is fixed.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a configuration like 2-10×32. These numbers suggest the zoom of the scope could be changed between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power adaptation is accomplished by working with the power ring component of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some advised scope powers and the distances where they may be effectively used. High power glass will not be as effective as lower powered scopes considering too much magnification can be a negative aspect depending on your shooting distance. The exact same concept relates to extended distances where the shooter needs to have enough power to see precisely where to properly aim the rifle.
About Lens Coverings
All top of the line rifle optic and scope lenses are layered. Lens finishing can be a significant aspect of a rifle’s setup when considering high end rifle optics and scope setups.
HD Versus ED Scope Lens Coatings
Some scope manufacturers likewise use “HD” or high-definition lens finishings which use different techniques, chemicals, polarizations, and elements to draw out a wide range of colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Scopes
Different optic lenses can likewise have various coatings applied to them. All lenses usually have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic.
This lens treatment can offer protection to 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 coated lens depends on the scope manufacturer and how much you paid for it.
Some scope manufacturers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the maker’s lens treatment technology and the quality of products used in constructing the rifle scope.
Hydrophobic Covering for Glass
Water on a scope’s lens doesn’t help with retaining a clear sight picture through a scope at all. Numerous top of the line or high-end scope producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface area of the Steiner optic lens so the water particles can not bind to it or create surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Alternatives for Mounting Glass on Long Guns
Mounting options for scopes come in a few options. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally are made in quick release variations which use manual levers which permit rifle operators to rapidly mount and dismount the optics.
Hex Key Rifle Glass Ring Mounts
Standard, clamp type mounting optic rings use hex head screws to fix to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for long distance accuracy shooting. This type of scope mount is great for rifles which are in need of a durable, unfailing mount which will not change regardless of how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should have for a specialized optics setup on a long distance scouting or sniper competition firearm which will hardly ever need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the screws to stop the hex screws from wiggling out after they are mounted firmly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Scope 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. Multiple scopes can also be switched out if they all use a compatible style mount. These types of mounts come in handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used in between multiple rifles.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle optic can spoil a day on the range and your costly optic by resulting in fogging and making residue inside of the scope tube. The majority of optics prevent humidity from going into the optical tube with a series of sealing O-rings which are waterproof. Typically, these water-resistant optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture content prevention for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle boating and are concerned about the scope still performing if it falls overboard and you can still recover the firearm.
Glass Gas Purging
Another element of avoiding the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Since this area is already occupied by the gas, the glass is less impacted by temp alterations and pressure distinctions from the outdoor environment which may potentially permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
