Certification of Contact Lenses as Calibration Standards

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.
