Reichert 11635B Plus Cylinder Ultramatic Phoroptor /Phoropter

PRODUCT DESCRIPTION: 

The original and best refracting instrument, Phoroptor continues to be the industry standard after more than 90 years, offering world-renown mechanical quality and craftsmanship. The Reichert Phoroptor is the only refracting instrument completely designed and manufactured in the United States. Each Phoroptor is made of nearly 1,000 pieces, assembled by hand in our Buffalo, New York factory.

Every Phoroptor has that unmistakable feel of quality. The smooth rotation of the dials. The virtual absence of play in the mechanisms. The precise, solid click of the control knobs. Constant reminders that you're using the world's finest refracting instrument. It's a fit and feel no one can duplicate, any more than they can duplicate the Phoroptor's optical quality, accuracy and reliability.
