This robust static blocker offers long term precision blocking for spherical and prism lenses.

  • It requires only a single calibration at setup.
  • The four alignment axes ensure precise blocking.
  • It can be used as a prism blocker with cylinder axis layout, and it easily adjusts for button tilt and radial run-out.
  • The “smart” air-actuated, pressure controlled collet automatically adjusts to any standard 1/2 blank at consistent pressure without warping or crimping the lens.
  • The dead-length-stop provides precise thickness for high volume production.
  • A digital gauge measures to .001 mm with uninterrupted memory.
  • The durable, cast iron base offers the versatility of horizontal or vertical operation.
  • With precision arbors, less than .005mm eccentricity (prism) will routinely be achieved.
  • An optional analogue thickness gauge is available.
  • Custom models are available.
