Certification of Contact Lenses as Calibration Standards

Posted May 18, 2020 by Kristin

Quality control processes can often lag behind advances in technology. For example, ultrasonic sensors that require daily cleaning and re-calibration are widely utilized despite the existence of more accurate and maintenance-free optical metrology solutions. To bridge this gap, manufacturers adopt cutting-edge technology to certify standards. These standards are used to calibrate or confirm performance of older deployed equipment.

The attached application note provides details of such a process employed by contact lens manufacturers to certify standards for calibration of ultrasonic sensors. Lumetrics has a dedicated laboratory where our proprietary light based measurement technology is used for certifying contact lens standards based on center thickness and sagittal height.
