Natural Light Mixing Technology: Natural Light Mixing Technology: Based on the conventional LED light source, the light source with four different color shades is integrated into one lamp bead and pre-mixed in the convex lens to maintain a stable white light throughout the lighting path.

Doctors can choose to focus on different tissue structures such as heart, blood vessels, fat, etc. to enhance the display effect of the key tissues and weaken the color rendering of other tissues.
