The Legend Returns- Redfield to Launch American-Engineered, American-Assembled Rlflescopes
REDFIELD, a name synonymous with fine riflescopes for decades, is now offering shooters the opportunity to own the most innovative and technologically advanced riflescopes ever produced anywhere by anyone. Under the engineering leadership and innovative spirit of its parent company, Meade Instruments, Redfield will soon introduce a line of incomparable new riflescopes that will be completely designed and assembled in the United States, with component parts produced in some of the finest factories in America and offshore.
Meade Instruments, a California-based optical manufacturing company, has directed its engineers to create the finest riflescopes in the world with features and innovations never seen before. They have achieved that mission, and these scopes will proudly carry the Redfield name, while setting the standard for riflescope design for decades to come.
INNOVATIONS IN RIFLESCOPE CONSTRUCTION
A True One-Piece Main Body Tube.
Riflescope construction begins with the main tube. While other optical manufacturers have long boasted of one-piece main tubes, in traditional scopes this means one piece from the eyebell forward. Redfield engineers employ the first and only true one-piece tube in the construction of all new Redfield scopes. This new, amazingly lightweight tube is created from a magnesium alloy, then precision machined as a one-piece unit, end to end, for unquestioned strength and integrity. This is a unique method of scope tube construction that makes the new Redfield riflescope more rugged and more durable than any scope in its class.
The Patented TrueZero™ Flex Erector System.
But the new main tube is just the beginning. Redfield engineers have also incorporated its patented TrueZero Flex Erector design in the construction of the internal erector tube. The traditional gimbal/biasing spring design has been replaced by an erector tube solidly attached to the scope body, with increased flexibility at the normal gimbal point being provided by special grooves in the unique material of the erector.
Recoil has always been one of the largest contributors to a shifting point of impact within riflescopes. This technologically-advanced design greatly reduces the effects of recoil by holding the erector system solidly to the main tube and by absorbing and dissipating a portion of the recoil energy. For the shooter, this means the introduction of either parallax or point of impact shift due to recoil is dramatically reduced, if not completely eliminated. Also, because this dissipation of recoil reduces stress within the scope, and since this design eliminates many of the parts traditionally used in erector tube construction, there is a greatly decreased probability of system failure anywhere within the scope. Fewer parts mean less chance of anything going wrong.
Another large contributor to a shifting point of impact is a change in the point of aim caused by the biasing spring, which is used to apply tension and force at the end of the erector tube against the dial pads. This spring has been the cause of many errant shots for two reasons: One, the spring often weakens over time, becomes less responsive, and causes the point-of-aim to shift. Two, "drag" is created where the traditional erector contacts the spring, keeping the erector from returning to the same point after each shot, and causing a shift in the point of aim. When your point of aim shifts, so does your point of impact.
The unique design of this revolutionary new erector allows it to maintain an even pressure from end to end, eliminating the need for a biasing spring altogether, while maintaining a consistent optical path. The responses to windage and elevation adjustments are immediate and precise. No more tapping on the turret to be sure the adjustment "sets."
Unprecedented Magnification Range in Redfield's New 5X Zoom System.
All Redfield scopes will feature a new 5X zooming system that has never been accomplished in the history of commercial riflescope production. Variable-powered riflescopes typically feature a 3X or 4X zooming system. To illustrate, a 3-9X scope has a 3X system, where the lowest magnification multiplied by three gives you the higher magnification. Similarly, a 6-24X scope has a 4X system. Before now, the limitations of the design have restricted a greater range. Redfield's new scopes deliver an incredible 5X power range from low to high magnification. No line of riflescopes ever produced has featured such a broad range of magnification.
This new zoom system achieves its 5-times power range through use of a patent-pending 3-cam zooming system, a unique method of providing the extra magnification range within the scopes' erector system. As a result, these riflescopes exhibit ultra-high performance with no point of aim shift across an unprecedented range of magnification. The versatility and potential applications for these scopes is extensive; everything from hunting dangerous game at up-close and personal ranges, to long-range target or varmint shooting is possible with these new Redfield scopes.
Re-Settable, Low-Profile, TrueZero ™
Windage and Elevation Dials Redfield has long understood that to be successful in the field, you need sealed dial adjustments that are precise, repeatable, and capable of holding zero under any recoil conditions over time. To ensure that your bullet impact is right where you want it to be each and every time you pull the trigger, Redfield engineers have completely re-designed our windage and elevation adjustments using our trademarked TrueZero™ ball bearing and spring adjustment system as the base design feature. Their precise and audible clicks, reliability and accuracy over time, and waterproof construction make them the perfect basis for the premier dial design on the market today. With a low profile and target turret-style features, they are offered in both 1/4- and 1/8-MOA versions, depending on the scope model. As an added bonus, the days of breaking out a screwdriver or Alien key to reset your dials to zero are gone. To adjust the new Redfield dials, simply push down on the dial, turn the indicator to zero, and allow the dial to pop back up and lock into place.
Side-Focus, AccuClick ™ Parallax Adjustments; Power Change Ring; Diopter Adjustments
Three models in the Redfield line will feature our newly-designed side-focus parallax adjustments with AccuClick yardage stops. By changing the location of the adjustment from the objective bell to the saddle area, parallax and fine focus adjustments can be made while maintaining your target in the full field of view. All Redfield power change rings also include our new AccuClick design that features positive stops at each magnification setting. Similarly, all Redfield fast-focus eyepieces include our new AccuClick design with 1/8 diopter adjustments over the entire dioptric range.
INNOVATIONS IN OPTICAL DESIGN
With all the mechanical innovations in the new Redfield scope, it might seem that optical performance has been overlooked. Not so! Redfield's optical engineers set out to design an optical system that would stand out as the yardstick for measuring all other designs, and they have succeeded in creating a new optical system as revolutionary and innovative as the mechanical features housing it. Using exotic types of optical glass, precision optical coatings, and some of the most innovative optical designs ever conceived, these new riflescopes elevate the Redfield brand to its traditional place at the top of the pack.
Apochromatic Objective Lenses
The journey begins at the objective lens of the scope. What you see with your eye is a direct result of what passes through the objective lens, so it's important that as much light as possible makes it through the lens and equally important that the image produced is an accurate representation of the object being observed. As light passes through a lens, some of that light is lost at each surface of the lens due to reflection, so it's important to reduce the amount of lost light as much as possible. Lens coatings are the accepted means of reducing this lost light, and there are various types of coatings used throughout the industry, each achieving a certain level of lost light reduction. Most high-end riflescopes feature fully multi-coated lenses because they have the greatest amount of success in reducing lost light, Redfield and Meade optical engineers have raised the bar even higher. By using precision, broadband coatings to fully multi-coat each lens, they have reduced lost light by an extra .2% per lens surface - a full 2.8% overall -compared to other fully multi-coated lens systems, thus assuring the maximum amount of light possible passes through the objective lens.
Chromatic aberration, or "fringing," is another problem that has plagued optical designers for years, particularly at higher magnifications. Chromatic aberration occurs in a rifiescope when the objective lens bends white light towards the reticle. The white light then separates into different colors, each color bending at a slightly different angle. The result is that all the colors don't focus at the same point. This is easily recognized and most often described as a "bluish" or "yellowish" edge on the image, particularly straight black and white edges.
In most scopes, chromatic aberration is reduced by using multiple lens elements -usually two, but sometimes as many as five - composed of different types of glass. The combination of low-dispersion positive lenses and high-dispersion negative lenses results in the red and blue colors recombining. Although a cost-effective improvement, this method adds weight and does nothing to bring the green light back into focus with the blue and red light. The best it can do is to minimize the focus separation between the green light and red/blue light, causing residual color fringing in the image. This was not the result Redfield's optical engineers were looking for.
Instead, Redfield uses a more expensive, Extra-low Dispersion (ED) exotic glass in the construction of its objective lenses. This ED glass does not disperse or separate the colors as much as its higher-dispersive counterparts, thereby allowing Redfield's designers to bring the red, green, and blue light to focus. These special apochromatic lenses (APOs) eliminate the need for heavy compound lenses, and they generate a true white image, giving the user the truest achievable representation of the image.
Redfield's QTA™ Plus Quick Target Acquisition Eyepiece.
Redfield's optics designers have taken its already-impressive QTA™ eyepiece design to a new level through use of exotic optical glasses and additional lens elements. Redfield's new QTA™ Plus eyepiece still delivers a larger eyebox that allows the shooter to quickly acquire the target and places the eye at a safe and comfortable distance from the eyepiece, while allowing for increased vertical and horizontal, as well as forward and backward movement behind the scope.
This increased tolerance to up-and-down and side-to-side head movement while still maintaining a clear view of the target results in quicker target acquisition that is absolutely critical in many fast-paced hunts where a split second can make a big difference. Now, however, through use of high density Lanthanum glass and by adding a glass aspheric lens precision manufactured in its California facility, Redfield's new eyepiece delivers a constant 4 inches of eye relief throughout the entire 5X zooming range and one of the most distortion-free images available.
