    • Abstract
  • For the existing measurement system of lens center thickness based on optical confocal technology, refraction and reflection of incident light affected the measuring accuracy. In order to solve this problems, based on confocal technology, the modified measurement system of lens center thickness was designed with the method of double-side optical confocal measurement. After theoretical analysis, error analysis and experimental verification, the results show that the measurement range of the system reaches 30mm and the measurement accuracy is 2m. The system can get the high-speed untouched measurement of center thickness and satisfy the demands of actual measurement.
