Each binocular is 100 % inspected for optical and material quality before shipping. To attain optimal image quality, all lenses and prisms are produced in a highly precise way. If one extends the optical axes of the prisms, the deviation at the distance of 50 yds/50 m may not be more than the thickness of a sheet of paper. The patented Swarotop and Swarodur coatings on lenses and prisms reduce surface reflections - which normally absorb about 6 % of the light to as little as 0.2 %. The result: the brightest images with greatest contrast. Airtight, dustproof and watertight to a depth of 13 ft/4 m on account of the interiorfocusing system and the nitrogen filling: no internal fogging, and 100 % functional reliability from -20 to +55 C/-4 to +131 F.
Hi Caryn!Thanks so much for stopping by! I ctaree the background image using a slide from Keynote (Mac's PowerPoint if you will). There is an option in Keynote to put a stroke around an image, and there are lots and lots of options, including making
