  • According to the requirements of a three-dimensional laparoscope consisting of many group lenses for the high transmittance and distortionless imaging, the appropriate film materials were chosen. Then, a coating design softwave was taken to realize the nonperiod coating system design of the anti-reflective coating by using the vacuum evaporation method and an ion assistant deposition system. By adjusting parameters of coating film and using the technique of optical control and crystal control simultaneously, the thick control error was reduced and the anti-reflection coating was coated on the lenses that were used in the laparoscopy successfully. The test results demonstrate that the average reflectance of the preparated coating is less than 0.5% and it shows color distortionless, securely layers and better effects of resistant to corrosion. These results meet operating requirements of medical optical instruments.
