All About Glass
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target over a distance. They do this through magnifying the target using a set of lenses inside the scope. The scope’s alignment can be dialed in to take into account varied natural factors like wind and elevation to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based upon the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the intended target. The majority of modern-day rifle optics have around 11 parts which are found inside and externally on the scope body. These scope parts include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other elements. Learn about the eleven parts of rifle optics.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Choosing the finest type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Optics
First focal plane glass (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards by using 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who have an idea for their target “hold over” as well as “lead” correlations for their firearms
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight space than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the magnification lens. 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.
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most of the shots take place within much shorter spaces and ranges
- Shooters who want a clearer optic picture with less room taken up by the larger sized FFP reticle
Rifle Scope Magnification
The quantity of zoom a scope offers is identified 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.
Fixed Single Power Lens Rifle Glass
A single power rifle optic and scope will have a zoom number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not change given that it is a set power scope.
Adjustable Power Lens Optic Info
Variable power rifle scopes can be changed between magnification levels. These types of scopes will list the zoom degree in a format such as 2-10×32. These numbers suggest the magnification of the scope can be set in between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power modification is achieved utilizing the power ring part of the scope near the back of the scope by the eye bell piece.
Optic Power and Ranges
Here are some recommended scope power levels and the distances where they could be efficiently used. Keep in mind that higher power scopes will not be as practical as lower powered scopes because too much magnification can be a negative thing in certain situations. The exact same concept goes for longer distances where the shooter needs enough power to see where to best aim the rifle.
About Rifle Scope Lens Finishes
All contemporary rifle optic and scope lenses are coated. There are various types and qualities of glass lens coverings. Lens finishing can be a crucial element of a rifle when looking at luxury rifle optics and targeting units. The glass lenses are one of the most significant pieces of the glass due to the fact that they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens surface and even improves anti glare from refracted direct sunlight and color presence.
HD Versus ED Rifle Scope Lens Coatings
Some optic producers will also use “HD” or high-def lens finishes that apply different processes, chemicals, aspects, and polarizations to draw out numerous color ranges and viewable target definition through the lens. This HD covering is commonly used with more costly, high density glass which decreases light’s opportunity to refract by means of the lens glass. Some scope vendors use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration is often obvious over things with well defined shapes as light hits the object from specific angles.
Rifle Scope Lens Single Coating Versus Multi-Coating
Different optic lenses can also have various coatings used to them. All lenses normally have at least some type of treatment or finishing used to them before being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is typically a protective and boosting multi-purpose treatment. This lens treatment can protect the lens from scratches while reducing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope designer and the amount you spent on it. The scope’s maker and cost are indicators of the lens quality.
Some scope makers similarly make it a point to specify if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Info on Hydrophobic Finishing
Water on a scope lens does not improve preserving a clear sight picture through an optic whatsoever. Numerous top of the line and premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the exterior of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to keep a clear, water free sight picture.
Scope Mounting Options
Installing approaches for scopes come in a couple of choices. There are the standard scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally come in quick release variations which use throw levers which permit rifle operators to rapidly install and dismount the optics.
Hex Key Scope Ring Mounting Solutions
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation 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 developed for long distance accuracy shooting. This type of scope install is great for rifles which need a durable, sound mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly take off a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, multiple scopes can also be swapped out in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten firmly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining precision. These types of mounts are useful and handy for shooting platforms which are transferred a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are used between numerous rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle glass can destroy a day of shooting and your pricey optic by resulting in fogging and making residue within the scope tube. The majority of scopes protect against humidity from entering the optical tube with a series of sealing O-rings which are waterproof. Generally, these 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 ample moisture prevention for common use rifles, unless you plan on taking your rifle on a boat and are worried about the scope still functioning if it is submerged in water and you can still recover the firearm.
Details on Rifle Glass Tube Gas Purging
Another component of avoiding the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the optic is less affected by climate changes and pressure variations from the outdoor environment which could 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 look for.
