Engineering

The DAC International Engineering Department is headed by Rod Keller, Vice President, Engineering. In 1993, Rod received the Contact Lens Manufacturers Association (CLMA)
Trailblazer Award. He is credited with design of the world's first computer-controlled contact lens lathe.
   The Engineering Department includes mechanical engineers, electrical/electronic engineers, software engineers, and support staff. Designs are produced on modern CAD systems that are integrated into the company's in-house network. Among our many proprietary developments is the Digital Motion Control (DMC) which is installed in the on-board dual computer. DMC is the interface that controls the motion and functions of the lathe. The two computers, on a single backplane - one for input from the outside world, the other to handle complex calculations - provide typical resolution of 10 nanometers. DMC utilizes FIR filter technology to ensure exact control of the fast tool servo system.

   DAC International Software Engineering has developed and writes all the operating files in DAC Script Language (DSL). This interpreted language is open for competent engineers to create their own algorithms.
   

Applications Engineering

   The DAC International Applications Engineering Department has a Contact Lens/IOL Laboratory and a Spectacle Lens Surfacing System Laboratory. In the contact lens area, special designs are developed for customers using DAC Script Language.

   The Spectacle Lens Laboratory is used to turn and polish Rx and PAL lenses to ensure quality, accuracy, tool life and production time.  The DAC Specialty Lens Menu of the RxD has been developed and offers several lens designs for low vision and difficult to fit patients such as balanced slab-offs, blended lenticular, and more.
