摘要

This study set up a portable measurement system for anti-blue light lens, its characteristic is using a light pulse modulator and filtering circuit technology to prevent ambient light interference and no need to used optical filters. Electronic Pulse wave signal by half-wave conversion circuit enables the microprocessor to do calculations. The system composed by the transmitter circuit, receiver circuit and signal processing circuit. The transmitter circuit use Darlington drive circuit to optimize the LED operating current, so that it can be obtain the strongest pulsed light. Through the experiment prove that transmittance measurement accuracy is up to 6%, the anti-blue lenses brown 20% (transmittance is 80%), blue film anti-blue light lenses having anti-blue light effect, and measuring obtain the object color deviation within 3%.
