This combination of a 7-1/2" diameter, distortion-free lens with a 34-watt circline fluorescent lamp is ideal for PC board inspection. Its large lens provides over 130% more working area than standard circline magnifiers. This oversized lens allows a 12" board to be viewed in its entirety, increasing production and reducing eye strain. Full spectrum, glare-free bulb reduces bounceback on solder connections or any other shiny surface. Available in 3-diopter (1.75X magnification) or 4-diopter (2X) versions, with either a screw-down or clamp-on mount. Comes with 37"-reach springbalanced arm, ESD-safe shade, on/off switch, 3-wire cord, and fluorescent tube. Color: Light Gray.
