NumisView Triplet Loupe 10X

NumisView triplet loupes are crafted from three layers of high quality optical glass, not plastic, to provide a crisp image with minimal distortion. These lenses are corrected for spherical and chromatic aberration. The optical glass lenses are housed in a solid aluminum frame and swing away case. The case is riveted, not screwed, together and tested for 5000 opens and closes. Nylon spacers provide a smooth yet firm feel when opening and closing. Loupe comes with a metal box and lanyard.
