Abstract：Objective To develop a transparency testing equipment for tissue engineering cornea so as to evaluate the transparency of tissue engineering cornea objectively.Methods Based on the optical principles,the hardware platform of the transparency testing device for tissue engineering cornea was designed and built.Meanwhile,the corresponding software platform based on LabVIEW was developed.The system error of the instrument was determined through tests.Then the transparency values of resin lens and contact lens were detected 1000 times respectively to ensure the main performance indicators of the device.Moreover,the influence of different light intensity and wavelength on transparency were also discussed.Results It was found that the system error of the instrument was 0.028,the measurement accuracy was 0.0082 in the case of 90％ sample transparency,the repeatability was 0.0038,and the stability of one month was 0.0011.If the light could penetrate the media,the light intensity had no effect on the measurement.Although different wavelengths could make different results,the evaluation of transparency was not affected for fixed wavelength.Conclusion The tissue engineering corneal transparency testing equipment developed in this paper is of precise accuracy,perfect function and a certain reliability,and with good promotional value.
