Study And Fabrication Of Three-Dimensional Laparoscopic Face Broadband AR Coating

Three-dimensional laparoscopic consist of many group lens, it demands high transmittance and distortionless imaging. According to its practical requirement, choose the appropriate film material, adopt the method of vacuum evaporation coating and append ion assistant deposition, utilize coating design software to design and analyze, by way of adjust process parameters of coating film, put to use the technique of optical control and crystal control simultaneously, reduce the thick control error, manufacture anti-reflection film on many groups of the lens. Via testing:the average reflection of the preparation film less than 0.5% and distortionless colour, securely layers, better effect of resistant to corrosion, meet operating requirements of medical optical instrument.
