This Hastings Triplet 20x provides a very sharp and distortion free image. Three bonded lenses are highly corrected for spherical and chromatic aberrations. All metal construction; comes with leather case. End of housing has loop for attachment of a lanyard (not included). Focal length 1/2″, lens diameter 18mm. Made in China.
** Please note: We do not recommend a 20x hand lens for the beginning naturalist, due to the very small field of view and focal distance. This lens is much more difficult to use than a 10x.
