A handlens (loupe) is a critical item for all field biologists, geologists, gardeners, anyone interested in natural history or in observing the small things in the world that surrounds us. The Academy is now offering the Bausch & Lomb 14x Coddington lens (w/ lanyard); named after its British inventor, Henry Coddington. This is an excellent lens, and with proper care will last a lifetime. "In terms of performance, second to none."
