Keeler Instruments Inc, Broomall, Penn, introduces its new Mini Loupes. The loupes provide high resolution 2.5x magnification and weigh 34 grams. They use anti-reflective, coated  Schott glass. The loupes are designed to provide clear  visualization at a working distance of 34-50 cm while minimizing edge  distortion, and also feature a "flip up" hinge system that allows the  user to change viewing and posture angles. The loupes are attached to a metal mounting bar to help keep them stable during use. All Keeler loupes are available on the Keeler Sport frame (pictured) in a range of colors. The Keeler Sport frame can be worn over glasses, or a prescription can be incorporated into the holder.
