Immediately turn off the machine.

Disconnect all power and data cables from the post cure unit

Remove the fill stand set it aside

Tilt the post cure unit onto its back

Turn the machine around so that the fill stand plate is facing you

Tilt machine toward you and set the machine upside show on the fill stand plate with the drawer facing you

Tilt the unit toward you so that the drawer faces the floor

Open the drawer and gently shake the unit if necessary

The lens should fall out

 

Pack Your nanoCLEAR AR Unit Properly for Service

Posted on by

When returning your nanoCLEAR AR unit for service, always remember to follow the packing instructions correctly to prevent damage and unnecessary repairs.

Located in the back of the nanoCLEAR AR unit:

  • Remove power cord
  • Remove network data cable
  • Remove data cable from wash module
  • Remove video PC cable
  • Remove high pressure supply hose
  • Remove drain hose to wash module
  • Remove all chemistry inlet tubing and replace with white caps
  • Remove vacuum inlet
  • Remove monitor from stand
  • Remove monitor stand & push monitor plug down the tube that it is housed in

Located in side your nanoCLEAR AR system:

  • Remove black mold stages
  • Remove wash bowl ring
  • Remove chemistry ring
  • Remove chemistry bowl liner and discard
  • Remove chemistry bowl and clean all chemistry from bowl
  • Remove tips and filters and replace with red caps

Lock motion arm into position to prevent movement. If possible, place the motion arm in the chemistry bowl position and lower the arm. When the motion arm reaches the lowest point press STOP COATING BUTTON. Place bubble warp or packing material on either side of motion arm to prevent movement and install the shipping bracket provided.

Placing nanoCLEAR AR system in the special system box:

  • Place tape or the shrink wrap it came with on the front door panel to prevent door from opening during shipping

  • Gently place nanoCLEAR AR system into box making sure it rests inside the foam cut out inside of box
  • Gently place the top foam insert on top of the nanoCLEAR AR system and push into place
  • Close box and remove any labeling on the outside
  • Tape box closed and place the appropriate shipping labels on the outside

When your system has been boxed up and/or you have any questions, please call Optical Dynamics Technical Support at 8000-587-2743.

What Free-Form Is

Posted on by

At Optical Dynamics, we use digital free-from molds to produce customized lenses with improved optics and enhanced visual clarity. As published in Eyecare Business, the following six points are key to understanding the free-form process.

  1. The main difference between digital and traditional surfacing is digital surfacing’s ability to produce more complex surfaces with extreme accuracy.
  2. Digital surfacing can be used to create simple single vision or complex progressive surfaces. The ability of the lens to provide visual comfort and performance is determined by the quality of the design.
  3. Digital surfacing is referred to as direct-to-surface, CNC and free-from. All refer to basically the same process.
  4. The most significant variable involves the process used to calculate the design. Digital surfacing processes require significantly more calibration and control compared to traditional surfacing.
  5. There are two inherent benefits common to nearly all digitally surfaced PALS: reduction of marginal astigmatism and reduction of “rounding errors”.
  6. Remember: all lenses that bend light will have aberrations and spherical surfaces create aberration. Its a matter of how those aberrations are managed that provides a unique benefit to the wearer.
