Claim:
An apparatus for manufacturing a lens, comprising: a frame; a plurality of workstations disposed on the frame, at least one workstation applying a coating to the lens; a rotatable carousel disposed on the frame, the carousel having a hub and a plurality of arms, each of the arms defining a proximal end attached to the hub and an opposed distal end; a drive shaft mounted in close proximity to the distal end of each of the arms; a lens holder attached to each of the drive shafts; a first magnetic clutch attached to each of the drive shafts; and at least one spin drive assembly attached to the frame and including: a second magnetic clutch; and a spin drive which is operatively connected to the second magnetic clutch to selectively impart a rotational motion thereto; the carousel being operative to selectively align any one of the first magnetic clutches with the second magnetic clutch for allowing the second magnetic clutch to magnetically engage the first magnetic clutch aligned therewith and transfer rotational motion generated by the spin drive to the drive shaft and the lens holder attached thereto.
