Paper Abstract

In order to evaluate if an ophthalmic instrument has exempt status it shall not exceed any of the emission limits, we designed a relatively simple and inexpensive optical radiation measurement system that can be used to evaluate if an ophthalmic instrument is below the emission limits specified in the standard. The system can complete one measure of the spectral irradiance [in W/(cm*cm*nm)] from 250nm~1100nm in shortest time of 10us and the system is applicable to the instruments with continuous visible light output and pulsed light output.
