Rifle Glass Info
Rifle scopes permit you to precisely align a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by employing a series of lenses within the scope. The scope’s alignment can be adapted to account for numerous ecological elements like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will land based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have around eleven parts which are found inside and on the exterior of the scope. These optic pieces include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. Learn about the eleven parts of glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The sort of focal plane an optic has decides where the reticle or crosshair lies relative to the optic’s magnifying adjustments. It literally suggests the reticle is behind or ahead of the magnifying lens of the scope. Choosing the most desired kind of rifle optic is based on what style of hunting or shooting you anticipate doing.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. This induces the reticle to increase in size based on the level of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non magnified distance. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are very little
- Experienced shooters who recognize their aim point “hold over” as well as “lead” ratios for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight room than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle to the rear of the zoom lens. This triggers the reticle to stay at the exact same scale relative to the quantity of zoom being used. The final result is that the reticle measurements change based on the zoom employed to shoot over longer ranges considering the markings represent different increments which vary with the zoom. In the FFP illustration with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement. These particular varieties of optics work for:
- Far away forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most of the shots happen within shorter spaces and ranges
- Shooters who like a clearer optic picture without area taken up by the larger size FFP reticle
Ins and Outs of Rifle Optic Magnification
The amount of zoom a scope supplies is identified by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Rifle Glass
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 and the objective lens is 32mm. The zoom of this kind of optic can not change considering that it is set from the factory.
Adjustable Power Lens Rifle Scopes
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 adjusted in between 2x and 10x power. This always utilizes the power levels in-between 2 and 10. The power manipulation is achieved utilizing the power ring component of the scope near the back of the scope by the eye bell piece.
Glass Power and Range Correlation
Here are some advised scope power settings and the distances where they may be efficiently used. Always remember that high magnification scopes will not be as efficient as lower magnification level scopes since excessive magnification can be a detractor. The exact same idea relates to extended ranges where the shooter needs enough power to see exactly where to best aim the rifle.
Rifle Glass Lens Finishing
All present day rifle glass lenses are covered. Lens finishing can be an essential element of a shooting system when buying high end rifle optics and scope equipment.
Info on Lens Coatings – HD Versus ED
Some scope suppliers even use “HD” or high-definition lense coverings that use various processes, chemicals, aspects, and polarizations to enhance numerous color ranges and viewable definition through the lens. This high-definition finishing is frequently used with more costly high density lens glass which decreases light’s potential to refract by means of the lens glass. Some scope vendors use “HD” to refer to “ED” meaning extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic aberration or difference which is similarly called color distortion or fringing. Chromatic aberration can be noticeable around items with hard outlines as light hits the object from certain angles.
Glass Lens Single Coating Versus Multi-Coating
Various optic lenses can even have different coatings applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic. Because the lens isn’t just 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 the lens will be optimally usable in lots of kinds of environments, degrees of sunlight (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering 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 upon the scope producer and how much money you paid for it. Both the make and cost are indications of the lens quality.
Some scope makers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This suggests the lens has had numerous treatments applied to the surfaces. If a lens gets numerous treatments, it can show that a maker is taking numerous actions to combat various natural aspects like an anti-glare covering, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This also does not necessarily imply the multi-coated lens is much better than a single coated lens. Being “better” depends upon the producer’s lens treatment techniques and the quality of glass used in building the rifle glass.
Hydrophobic Lens Covering
Water on an optical lens does not support maintaining a clear sight picture through a scope at all. Many top of the line and premium optic makers will coat their lenses with a hydrophobic or hydrophilic finishing. The Steiner Optics Nano-Protection is a good example of this type of treatment. It deals with the exterior of the Steiner optic lens so the water molecules can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Choices for Mounting Glass on Firearms
Mounting approaches for scopes come in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also usually are made in quick release variations which use throw levers which permit rifle operators to quickly install and dismount the scope.
Rifle Glass Mounting Solutions with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which is created for long distance precision shooting. This type of scope mount is wonderful for rifles which need a resilient, rock solid mount which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a compatible style mount. These types of mounts are convenient for rifle platforms which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between several rifles or are situationally focused.
About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can spoil a day on the range and your highly-priced optic by resulting in fogging and developing residue within the scope tube. Many scopes prevent moisture from going into the optical tube with a series of sealing O-rings which are water resistant. Usually, 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 sufficient wetness avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are worried about the scope still performing if it goes overboard and you can still find the firearm.
Glass Gas Purging
Another element of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the scope is less influenced by temperature alterations and pressure variations from the external environment which could potentially permit water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
