The product with the new design has good repetition and adjustable frequency, which overcomes the limitations and shortage of traditional Xenon lamps. It ensures that the glaring strength not affected by the stimulating frequency and has the monochromatic lights (red, green, blue, yellow) being sensitive to a bright and dark system of the retina.
Detailed profile
