Laser classification and hazard evaluation require certain laser beam parameters to perform the required measurements and calculations. When parameters are provided to one performing a laser safety evaluation, the evaluator is often given from the manufacturer’s specifications which are based on performance of a laser or laser system. While the performance numbers are not incorrect, they often are not what a laser safety evaluator really needs to do their measurements or calculations to perform a reasonable, realistic laser hazard evaluation.

激光危害评估的性能数字与安全数字

激光分类和危害评估需要特定的激光束参数来执行所需的测量和计算。当向执行激光安全评估的人员提供参数时，评估人员通常根据制造商的规格提供，这些规格基于激光器或激光系统的性能。虽然性能数字并非不正确，但它们通常不是激光安全评估员真正需要进行测量或计算以执行合理、现实的激光危害评估。
