The rectangular-shaped magnifying lens "stretches" the 5" circular viewing area to 6.75". This wider viewing area allows for comfortable vision with both eyes and also reduces eyestrain and fatigue. Visual scanning speed is increased because more surface area is magnified at any given position. 3-diopter (3/4x magnification) lens is made of distortion-free, crown-optical glass and measures 6.75" x 4.25". The magnifier's powerful 18-watt compact fluorescent tube produces 130 footcandles at 15" above the work surface. Exact positioning of the light source behind the lens allows for a choice between even, shadow-free illumination or a highlighting effect. Contemporary "floating arm" with counter-balanced spring has 40" reach. Equipped with clamp-on table bracket and 3-conductor power cord. Available in an ESD-safe version that is ideal for the inspection of electronic parts and circuit boards. Color: Dove Gray.
