Abstract:
Objective To test and evaluate measurement uncertainty and relational performance parameters of the verification device for laser protective spectacles.Methods By using realtime beam-splitting surveillance,several performance parameters,including the measurement repeatability of the verification device,optical density of laser protective spectacles in different laser exposure conditions and its damage threshold,were tested.The measurement modules of the main performance parameters were built up as the experiment & technology platform for performance evaluation of laser protective spectacles and for measurement uncertainty appraisal of verification device.Results Laser wavelengths of the verification device were 1064nm and 532nm,response range of wavelength was from 0.4?m to 1.1?m,measuring range of laser energy was from 10-8 J to 0.3J,measuring range of optical density for laser protective spectacles was from 0.1 to 8.0,measuring repeatability was 0.37%,and measuring uncertainty was 5% (k =2).Conclusion The automatic verification device is steady and reliable.The achieved performance indexes accord with the designed requirement for laser protection.
