Bare aluminum provides excellent reflectivity from the UV to the IR. Unfortunately, it also oxidizes rapidly and use of a dielectric overcoat is usually required to prevent degradation. Since no overcoat is ideal for all applications, materials best suited to the intended application should be chosen.

Aluminumreflectivity vs wavelength

If you have a hard to fit face or are looking for the most economical option, pick a spherical goggle.  If you are looking for the best optical clarity, peripheral vision and anti-fogging properties, go with the cylindrical lenses.

Spherical goggles we call “bubble” lenses. They are a more rigid, inflexible lens. They “bubble” out in the front. They have several advantages.  First, it gives you a much wider field of vision especially on the periphery.  Secondly, since the lens bubbles out in the front, it tends to sit further from the face to allow more “gap” between your face where you are generating body heat and the lens. This will help with fogging.  Lastly, the manufacturing process for bubble lenses creates less glare and distortion.  It becomes rather complicated explaining the axes on which spherical and cylindrical are built on.  But the bottom line is that the manufacturing process of the spherical lenses creates less overall distortion and glare due to the angles the light comes through the lens at.  They also look “cooler” and more futuristic. But the price point is much higher on the spherical lenses versus the cylindrical.

On our website Sporteyes.com you’ll see references to “spherical” or “cylindrical” lenses on our ski goggles.  What does this mean?

Esco Optics is a leading manufacturer of custom and catalog optics, precision optical components, and ITAR optics in the United States.

Cylindrical Goggles  have been around for decades and what you may have been familiar with if you have been skiing for a long time. These goggles have a flexible lens so they “wrap” around the face better as they flex to conform with your facial structures. They are also less expensive.

Several dielectric coatings are available as overcoats, used to enhance reflectivity, durability, and/or longevity of the underlying metal.

For most mirror applications, metallic coatings offer the best performance/cost ratio over any other reflective coating. The three most common and effective types that Esco Optics offers are aluminum, silver, and gold. Please not other specialty coatings are available by request.
