Vortex Diamondback Binoculars

The company Vortex Optics is a relative newbie in the optics world. Founded in Middleton, Wisconsin in 2004, the company is just over a dozen years old.  Without decades of long term name recognition that optics companies like Bushnell or Nikon have, it can be hard for Vortex to stand out as the quality brand that it is.

For a prime example of the quality newcomer Vortex Optics has to offer, look no further than their Diamondback Binoculars. With nine sizes to choose from, each constructed with superior quality high-performance materials, there is a pair of Vortex Diamondback Binoculars to fit every user perfectly.

Phase-Corrected Prisms

There are two types of prisms to used in modern binoculars. When considering your purchase, there are two to choose from: Porro prisms and roof prisms. Porro prisms are the original binocular technology.

In the mid-1800s, an Italian inventor named Ignazio Porro designed all new technology to create a set of prisms for his telescope. He placed the prisms at right angles to both reverse the image (reflected images are upside down) and bend the path of the light as it passes through the lenses.

The invention of this new optics technology meant that Porro could get greater magnification from a shorter instrument. Up to that point, if you had wanted the ability to see farther, you needed to build a longer telescope. Porro prisms are offset inside the binocular frame. This set up creates better contrast and more light efficiency. These binoculars have a much wider body due to the offset prisms.

Roof prisms are designed to make binoculars lighter and more streamlined. This is accomplished because the objective lens is in line with the eyepiece. The precision manufacturing needed to accomplish this made roof prism binoculars much more expensive, but also simpler and more comfortable to handle. Today, roof prisms are the gold standard in the mid to high end binocular market.

Vortex Diamondback binoculars come with phase-corrected roof prisms. Phase correction is a coating applied to the prisms to produce sharper images. The phase correction accomplishes this by eliminating interference between different phases of light. The image is brought into better focus as a result of the correction.

Without the phase correcting coating on the prisms to improves resolution, the beam of light passing through the lenses will bounce out of sync after reflecting off of the prisms.

Multi-Coated Lenses

All air-to-glass surfaces on a set of binoculars should have a coating applied to reduce reflectivity and glare. This creates a sharper and brighter image at the eye. Lenses are coated at different levels. Generally, the more lens that are coated and the more coatings each lens has, the more costly the set of binoculars will be.

Coated optics: At least one lens, usually the eyepiece, has had a coating applied.

Fully coated: All lens have had at least one coating applied.

Multi-coated: At least one lens has multiple coatings, again this is usually the eyepiece.

Fully multi-coated: All lenses have multiple coatings

Multi-coatings create clear, high contrast images. The Vortex Diamondback comes with multi-coated lenses so even though it’s not the A+ level of fully multi-coated, you know these binoculars will deliver the solid resolution and brightness along with very accurate color reproduction.

In addition to multi-coated lenses, Vortex Diamondback Binoculars are also completely waterproof and fogproof. Waterproofing takes away the worry about inclement weather when taking your binoculars into the field. Fogproof binoculars are sealed with o-rings and filled with nitrogen. This makes certain that changes in external temperature won’t cause lens to fog over because there is no air inside the lens to cause condensation to form.

Tethered objective lens covers protect these high-quality lens from impact damage as well as scratches and smudges. Tethered lens covers hang conveniently from the ends of each barrel for easy on and off. You also won’t have to worry about misplacing your lens covers or getting them lost in a coat pocket or at the bottom of a daypack.

Best-in-Class Field of View

All sizes of Vortex Diamondback binoculars offer a class-leading field of view. The 8×42 Diamondback model has a 420-foot field of view at 1,000 yards! You won’t miss an iota of visual information while hunting, bird-watching, or just taking in the landscape.

To understand the sizing of binoculars is fairly simple. The first number is the magnification and the second number (after the ‘x’) is the size of the objective lens in millimeters. Greater magnification, such as 10x versus 8x, adds size and weight to the binoculars as well as cost.

Binoculars create a wide field of view with less zoom and an intermediately-sized objective lens. Vortex Diamondback 8×42 Binoculars are right in the sweet spot to give the viewer an adequate level of zoom and enough objective lens size for the largest possible field of view.

Rubber Armor

Don’t coddle your binoculars with gentle indoor use. Go outdoors to see the best of the world in the elements through a set of binoculars like the Vortex Diamondback. Thankfully, Vortex Optics has added seriously tough rubber armor to their Diamondback binoculars.

Rubber armor protections creates a non-slip grip whether the binoculars are wet or dry. It makes these binoculars about as worry-free in the elements as anything on the market today. Sleek design and light weight protected by rubber armor provides long-lasting strength in a package you won’t tire of carrying around all day.

Don’t worry that your binoculars getting damaged from an accidental impact. Additionally, rubber armor is also simple to keep clean. With warm water and a drop of gentle soap on a soft rag, they can look as good as the day you got them for years and years.
