Inspection and blocking unit for Rx lenses

You are here

The Inspection and Blocking Unit for Prescription Lenses is for use in laboratories that edge and mount lenses into frames.  This machine inspects the optical and dimensional characteristics and
measures progressive, multifocal, and single vision lenses. The progressive lenses can then be oriented and blocked according to the ink marks or according to the semi-visible marks on the lens.  Its simplicity, autonomy, and its throughput of 250 lenses per hour make this an invaluable addition to your process.
